(2018) Souza, Cintya Mikaelly Pereira Gaia; Rocha Júnior, Cláudio Jorge Gomes da; http://lattes.cnpq.br/5767471085192721; http://lattes.cnpq.br/3531454440394612
The human being seeks to always choose the best product or service in the course of life. Therefore, only making a quality item available is no longer sufficient. Consumers want to have their expectations surpassed. The present work is about a research whose main objective was to measure the degree of consumer satisfaction of the AgroecologicalFair and the Free Fair of the city of Serra Talhada, in order to identify criteria that lead to satisfaction, to describe their expectations according to with the reality evaluating from the point of view of the same the quality of the products. Data collection was done through the application of forms and the Net Promoter Score to analyze and quantify customer satisfaction. Among all the criteria evaluated the worst variable analyzed by the consumers of the Agroecological Fair was the price and this result is due to not all information from the buyers, and the Free Fair was the hygiene of the place that is due to the size of the fair and the lack of awareness of those who attend and those who try to maintain the order of the place. Through this study the level of consumer satisfaction was obtained on the products of the fairs analyzed in order to make a significant contribution to the improvement of the infrastructure and the socioeconomic conditions of the farmers and merchants and to help in the conquest of new consumers.

(2018) Vieira, Domingos Sávio Marques de Menezes; Evangelista Júnior, Walter Santos; http://lattes.cnpq.br/6728342264331935; http://lattes.cnpq.br/7384301568742851
The extracts of plants are recommended in family agriculture, characterized by small and medium producers, mainly related to the organic production. One way of obtaining compounds or plant substances is through the isolation of active principles or specific chemical group with insecticidal action, among them the alkaloids. The Prosopis juliflora algarobeira presents several substances with insecticidal and antifungal properties. Thus, the objective of this research was to evaluate the insecticidal effect of the alcoholic and aqueous extracts of algarobeira leaves on the black aphid of the common bean Aphis craccivora (Hemiptera: Aphididae). The experiment was carried out in the UAST experimental area. Statistical analyzes were performed by analysis of variance, using the Tukey test with significance level at 5% probability, using the Sisvar 5.6 (2011) computational package. It was observed that the dosages of FAT (100, 50, 25 and 10 mL / L) did not present significant toxicity, where there was no mortality of A. craccivora. Using the aqueous extract of the algaroba, a mortality ranging from 5.94% and 30.12% of the black aphid was observed. It is concluded that the algaroba extract presented low efficiency on the mortality of A. craccivora.

One of the problems related to water resources in Brazil, beyond the unconscious use of the water and overused by population, it’s your irregular geographical distribuition, so that only 3% of these resources are located in the Norteast, region that owns 27,3% of the population of the country and is characterized by high annual evaporations and low precipitation rates, which are even smaller in the Semiaridregion.In this context, one of the most important rivers of the state of Pernambuco and that constitutes the greater hydrographic basin is the Pajeú, which is born in the city of Brejinho -PE and flowsinto the Itaparica dam, with a river mouth located between the cities of Floresta and Itacuruba. Because it’s an intermittent river, one of the main initiatives of the public power to increase the water supply over time has been and continues to be the construction of large hydraulic works such as dams, whose purpose it’s to store water for supplying the cities and for the cultivation of land and animal breeding. Along the Pajeú River there are 30 reservoirs with a capacity of more than 1 million m³ of water, and the Serrinha dam has the highest storage potential with 311 million m³. Due to the lack of information on the current state of these water structures, the present work proposed to raise, between august and december of the 2018, the state of conservation and the operating dynamics of sixof the main water bodies of the Pajeú River and its tributaries.Therefore were done surveys in locoof the structural and operational aspectsof this dams, as well as approaches were taken with the managers of eachone.It was found that most of the structures shows a worrying derelictionscenario, with Brotas and Jazigo dams being the most serious cases and Saco I, which has the best condition among all of them, however all can be classified as high associated potential harm and high category therefore, prone to disruption if they remain without the short-term contemplation of a preventive management and maintenance plan.

(2018) Cruz, Aloísio dos Santos; Simplício, Josimar Bento; Vieira, Maurício Luiz de Mello; http://lattes.cnpq.br/4204641633941814; http://lattes.cnpq.br/1876691945804390
In the Semi-arid region of the Northeast, goat breeding and sheep farming are relevant activities in socioeconomic aspects for rural families. However, the inadequate management of chemical fertilization in this region has added serious environmental problems, and consequently, forage production has been hampered by misapplication of mineral fertilization in production systems. Thus, the objective of this research was to evaluate the response of two genotypes of forage sorghum submitted to different doses of manipueira.The experiment was carried out in the Statistical Unit of Serra Talhada, installed in randomized blocks, in a 4x2x4 factorial scheme, composed of four blocks of two sorghum cultivars and four doses of manipueira (0.0, 12.0, 24.0 and 48, 0 m3ha-1), totaling 32 experimental units. The evaluated characteristics were stem diameter (DC); plant height (AP); number of live leaves (NFV); number of dead leaves (NFM); weight of the green mass (PMV) and weight of the dry mass (PMS). In the interactions obtained by the ANOVA of the data, it can be observed that, of the growth parameters evaluated were significantly altered by the use of manipueira doses, for these variables we observed a quadratic behavior as a function of plant height (AP), the evaluation period (mL / pot) for the two sorghum cultivars IPA 2502 and BRS Ponta Negra, at the height of the IPA 2502 plant the dose of 168.34 mL / pot provided a maximum height of 67cm at 62.51 days , and for BRS Ponta Negra it reached a maximum height of 85 cm, with a dosage of 104.76 mL / pot at 68.65 days, in Figure 2 (a) and (b). For the variable diameter of the stem (DC) Figures 3 (a)and (b), the dose of 168.06 mL / vessel provided the IPA 2502 maximum diameter of 11.82 mm at 49 days, while for the BRS Tip The dose of 101.71 mL / pot provided a maximum diameter of 13.69 mm at 64.29 days. There was no influence of the different dosagesof manipulation for the number of live and dead leaves, total green mass and total dry mass of the leaves. cultivars IPA 2502 and BRS Ponta Negra. The use of manipueira in the conditions established in this research did not promote increases in the production of sorghum forage, however, further evaluations are necessary with new studies on the influence of this fertilizer, since the plants were conditioned to water stress.

(2018) Saraiva, Maria Monique Tavares; Silva, Luzia Ferreira da; http://lattes.cnpq.br/6320449537171549; http://lattes.cnpq.br/7157708100841122
This study analyzed the occurrence of restoration in two areas of the Federal Rural University of Pernambuco, Serra TalhadaAcademic Unit(UFRPE/UAST) with seed Bank of the State Park Mata da Pimenteira(PEMP) by means of Nucleadoras techniques and evaluated its potential when subjected to Controlled conditions. The work is organized in two chapters. The first refers to a study developed in the field in two degraded areas of UFRPE/UAST and were evaluated the seed banks of burlap and soil and burlap of two environments of the French, in the years 2016/2017 and 2017/2018, respectively. In the first year, twenty samples of burlap were collected at a depth of 5 cm and area of 1m ², constituted ten in each area of natural environment (Serra Branca and Pimenteira) of the French and transplanted to ten parcels in two areas. In the second year, five samples of more burlap soil were collected in a 10 cm layer, distributed to ten experimental units in each degraded area. The design used in both experiments was in random blocks, in the 2 x 2 factorial model with two seed bank environments and two degraded areas with five repetitions each. They were obtained in the experiment of the burlap 49 individuals, distributed in 12 families and 25 species and, in the soil and burlap experiment, 144 individuals distributed in 37 species and 18 families, with nine species in common. There was predominance of herbaceous and greater floristic diversity in the material coming from the area of natural environment two, of the park. The second chapter consisted in the evaluation of the seed bank contained in four points of the PEMP, two in each area of natural environment (Serra Branca and Pimenteira), subjected to irrigation and conditioning in two different environments of luminosity (shading and Full sun), it was also carried out tests to distinguish the soils of the studied points, by means of tests of infiltration and determination of the density and porosity. It was verified 114 individuals distributed in 31 species and 21 botanical families, with an emergency prevalence in the portions of the material from the natural environment Zone two and under shading conditions. It was concluded that the more soiled burlap transposition presents greater viability in ecological restoration, with better results when associated with soil conservation management techniques; And under controlled conditions the seed bank of the point near the water course in the Pimenteirapresented better potential restorative, optimized by shading of 70%.

(2018) Xavier, Tâmela Larissa Silva; Silva, Luzia Ferreira da; http://lattes.cnpq.br/6320449537171549; http://lattes.cnpq.br/8832131021527249
The gladiolus stands out among the cut flowers cultivated in Brazil, as soon as it presents ease of cultivation and rapid financial return. However, its growth and productivity can be altered as a result of changes in the meteorological elements. This study investigated the vegetative growth of the gladiolus submitted to different shading environments in Serra Talhada -PE. The experiment was conducted at the Academic Unit of Serra Talhada \UFRPE, from June 28 to September 1, in a completely randomized design in three cultivation environments, full sun (control), under black shading 70% (sombrite) and 70% thermo-reflector(aluminet). The Amsterdam variety (Gladiolus x hortullanus L), cultivated in polyethylene containers with a volume of nine liters, was filledwith soil, sand and vermiculite (2: 1: 1) and three bulbs per container. Biometric parameters were evaluated: plant height, number of leaves, neck diameter, and biomass: leaf dry mass, dry mass of the bulb and dry mass of the root. In addition, meteorological elements were monitored: air temperature, relative air humidity, radiation and wind speed. The highest values in relation to plant height occurred in the treatment with 70% shade. There was no influence of the use of the shading screens for the number of leaves, neck diameter and root dry mass. The use of the thermo -reflector provided a greater accumulation of dry mass of the leaves at the end of the experimental period and favored the process of releasing the nutritional demand of the bulbs to theaerial part, more efficiently than the other growing environments. The screens provided reduced temperature, increased relative humidity, marked reduction in global solar radiation, and reduced wind speed. RFA values were higher in the thermo-reflector environment when compared to the sombrite environment.

(2018) Alves, Hygor Kristoph Muniz Nunes; Silva, Thieres George Freire da; Jardim, Alexandre Maniçoba da Rosa Ferraz; http://lattes.cnpq.br/9981205244282499; http://lattes.cnpq.br/0213450385240546; http://lattes.cnpq.br/4208743875293068
Due to long periods of drought and the effects of climatic changes in the Brazilian semi-arid region, it is of great importance to use management that will circumvent these impacts in the rural environment. The use of plants tolerant to water deficit and the use of supplementary irrigation may be an alternative, where for good irrigation water management practice it is necessary to know the water requirement of the crop, evapotranspiration and the crop coefficient for conditions. Soil water balance is a technique that helps in the measurement of these components. Thus, the objective of this study is to quantify the evapotranspiration and the forage cactus cultivation coefficient in crops without and with the use of mulch in the semi-arid region of Pernambuco. The experiment was carried out at the Experimental Station Lauro Ramos Bezerra, belonging to the Agronomic Institute of Pernambuco - IPA, municipality of Serra Talhada-PE, from November 2014 to November 2015. The clone used was Opuntiastricta, submitted to four slides of irrigation (25, 50, 75 and 100%) based on reference evapotranspiration plus rainfed condition, and two cropping systems (without and with mulch). The experimental design was arranged in randomized blocks, in the factorial arrangement 5x2, in four replications, where the slices represented the plots, and the cropping systems, the subplots. Over time the soil moisture was monitored. The water balance method was applied in 14-day intervals, totalizing 21 periods, which was composed of evapotranspiration (ET), precipitation (P), irrigation (I), runoff (R), vertical flow of water in the soil (Q) and variation of soil water storage (Δh). The components of the water balance were integrated and compared between the treatments within each period, applying them to the tests of normality and homoscedasticity, and once significant, the analysis of variance, if necessary, the Tukey test (5%). The irrigation events added to precipitation during the 21 periods was 764.76 mm, with the months between August and November 2015 presenting the highest values of ETo (6.18 mm). There was no difference in the components of the vertical flow of water in the soil, capillary ascension and deep drainage (CA and DP, in this order) when compared to the systems of cultivation without and with mulch over the soil. When the crop evapotranspiration (ETc) was evaluated, a significant difference was observed only for periods 10, 18, 20 and 21. The ETc accumulated for both systems was -782.01 and -771.19 (SC and CC, in this order). The highest mean ETc value corresponded to periods 6 (10-Apr-2015) for the two SC and CC systems, with averages of (-5.06 and -4.75, respectively). For the crop coefficient (kc) only the periods 10,18, 20 and 21 were significant (p <0.05), the mean values of kc for the two systems were 0.57 and 0.56 (SC and CC, in this order). The use of mulching improved the conditions of forage cactus cultivation, although it did not present a difference in water consumption, providing close kc values.

Fracionamento físico do carbono no solo em função da irrigação e adubação nitrogenada
(2019) Espindola, Vitor Augusto Silva; Oliveira, Alexandre Campelo de; http://lattes.cnpq.br/8164135937542569; http://lattes.cnpq.br/4334208597286391
Variations in the carbon stock are not individual risk factors, these are natural and anthropic, as the natural islands are associated as characteristics of the region, such as climate and temperature of the region, the characteristics of textures, soil C concentrations. The anthropological factor is related to the performance standards of a strategy of changing characteristics of a business that is not before, such as the process of doing its initial business, the struggle for machines and leaching through an irrigation action. Such classes can be occasioned in reducing C concentrations in soil as a problem of soil quality, since this is a resource as a non-renewable resource. Because of this, a number of studies are focused on measuring stock concentrations through practical actions in a way that can lead to loss of inventory. From the total zero hours, from the total hours, from the zero. in the semi-arid region of Pernambuco. The experiment was conducted at the Serra Talhada Academic Unit (UAST) under field conditions, with a randomized block design, evaluation of forage sorghum and millet in consecutive cycles, applied to 4 irrigation slides (28, 36, 44 and 52 %). and 4 levels of nitrogen fertilization (0, 100, 200, 300 kg ha-1). In terms of results, the analysis of the needs of all cycles was made during the first year, showing the potential of applying the local experimental impact in its dynamics. There is a relationship between the COAM and the nitrogen so that an increase of its bases by the provision of soil N alone in the first cycle. There is a reduction in COP concentrations as a first time when doing a man's action when he does not interfere in the other. So, a dynamics of C not having alone in contact with the fact of being under the effect of nitrogen fertilization and irrigation, does not offer significant effects of the interaction between the two on TOC, but rather the action of both managements isolated form. Studies on the higher depths may also be needed because of soil characteristics.

The cultivation of guava (Psidium guajavaL.) is widespread throughout the world, [being a kind of reality with high economic and market potential, which, with this, still presents great possibilities of expansion around the world.]In Brazil, São Paulo and Pernambuco lead production, accounting for 36.3% and 31%, accounting for 67.3% of national production. However,diseases in guavain Brazil directly influence the productivityof this culture. Among the diseases, meloidoginose is one of the main causes of damage to guava producers. In this context, the work was evaluated as the aerial biomass problem and root portion of guava seedlings of cv. Paloma for two soil conditions leading to the three biological products. Soils were grown in areas of guiding guava in nematodes under two management, soil 1 with remnant characteristics and soil 2 in full culture, deposited in 10 L volume vessels that are projected with three products formulated with Bacilluspumilus, B. subtilis, B. amyloliquefaciens, Azospirillum sp., Pseudomonas sp., Rhizobium sp., Saccharomyces sp., B. licheniformis. With the end of the 90 days, with the measurement of the first planes, the fresh mass and the dry and dry mass, the diameter of the stem, pair of leaves, number of leaves and number of branches. The experiment was carried out without a randomized complete block design (DBC) with eighttreatments and four replications where the treatments, arranged in a factorial scheme 4 x 2. The results were those biological products tested in this experiment, not having as parameter the biomass differences in question relation to the two types of cultivated soils.

Urban trees provide numerous benefits to the population. However, the lack of planning for the implantation of tree plants results in recurrent problems in the urban environment. Thus, this work had as objective to elaborate the Municipal Plan of Urban Arborization in the Serra Talhada /PE city. For this, initially, a survey was made on the history of the urban arborization of the city so that, later, make a diagnosis of a neighborhood as a sample. The diagnosis of the trees was performed using a technical assessment sheet, with the following data: location, species identification, plant size, types and identification of the site, interferences, relationships and diagnosis, and diseases or pests. Still, the general assessment and actions with some immediate management when necessary. The development and behavior in the urban environment of three native species: pajeú (Triplaris garderiana Wedd.), tamboril (Enterolobium contortisiliquum (vell.) Morong) and amendoim bravo (Pterogyne nitens Tul) were also evaluated. According to information collected on the history of the urban arborization of Serra Talhada / PE, they were introduced to the city for aesthetic reasons. In the inventory of the Alto da Conceição neighborhood, there were 202 trees, among them, the most frequent species was Ficus beijamina L., an exotic tree plant, considered unsuitable for planting in urban areas. In addition, it was possible to identify conflicts with electric wiring, with 19.80% and damages of pavements, with 17.82% of the plants. The growth of pajeú, tamboriland amendoim bravo species was satisfactory and indicated for urban planting. In this way, this collected information will help in the elaboration of the Municipal Plan of Urban Arborization, to avoid future.

(2019) Bezerra, Raul Caco Alves; Leite, Maurício Luiz de Mello Vieira; http://lattes.cnpq.br/4204641633941814; http://lattes.cnpq.br/7402898770018256
Ptarmigan grass (Digitaria pentzii Stent.) is a perennial, stoloniferous, drought-tolerant and intense grazing grass, and has reached high dry mass under semi-arid conditions. The objective of this study was to evaluate the management of cuttings in the morphogenetic and structural characteristics of pangolão grass. The experiment was conducted from July to November, 2018, in the experimental area of the Group of Studies in Forragicultura, Federal Rural University of Pernambuco, Academic Unit of Serra Talhada, micro region of Sertão do Pajeú. The experimental design was a randomized complete block design with 3 x 3 factorial design, with three pre-grazing heights (30, 40 and 50 cm) and three post-grazing (10, 15 and 20 cm) heights, with four replicates. The foliar leaf length, leaf blade width, stem length, stalk diameter, number of tillers, number of leaves: expanded, growing, senescent and leafy, were monitored every seven days withmonitoring of the growth of pangolon grass. dead Weighed fresh and dry mass of leaf blade, stem and panicle. The percentages of the morphological components were determined. The leaf area was estimated in a non-destructive manner, based on the linear length and width dimensions of the leaf blade. The data of the evaluations were submitted to normality test, homoscedasticity and to the analysis of variance by Test F. When the F was significant, the means of the treatments were compared by the Tukey test at 5% of probability. The pre-grazing height 30 cm gives higher dry mass values. The pre-grazing height of 50 cm presents a larger number of tillers and senescent leaves. The post-grazing at 10 cm of height presents higher phytomass values of the pangolão grass, independently of the pre-grazing height. The post-grazing at 15 and 20 cm associated with the pre-grazing of 50 cm provides a greater number of dead leaves. The pre-grazing height of 30 cm and post-grazing of 10 cm is presented as the best cut management for the pangolão grass. The product of the maximum leaf width length is a suitable parameter for use as an independent variable in the prediction of the leaf area of the pangolão grass, through regression models. The power model, Y = CL1,007, can be used to determine the leaf area of the pangolão grass, independently of the cutting height, with bases on the leaf blade length and width values of thisspecies.

The onion Allium cepa highlights-like vegetable important socioeconomic for the country, the predominance of culture medium, small producers and the family nature, generating about 250 thousand direct jobs in production. How the culture has its phytopatological problems, the decision has been made for the economics made from the production of the largest production in production. In order to control the problems, the tests are being studied and the biological control of the main focus is the use of nematological bacteria and fungi that promote the protection of the roots of the growth, besides promoting an increase in the biomass of the plants. The use of the microorganisms may have had an important relation with the potential of soil management, cleaning of the ecosystem of systems and the suppressive. The objective of this study was to evaluate the biomass of hybrid 1205 and Serengeti crop plants grown on soils with three biological products. Three bioproducts will be tested: product 1 containing bacteria: Bacillus pumilus 1.0x10¹¹ (endospores / L), Bacillus subtilis1.0x10¹¹ (endospores / L) and Bacillus amyloliquefaciens 1.0x10¹¹ (endospores / L), Product 2 have the bacteria Azospirillum sp. 1.0x109 (UFC / dose), Pseudomonas sp. 1.0x109 (CFU / dose), Rhizobium sp. 1.0x109 (CFU / dose) and the fungus Saccharomyces sp. 1.0x109 (CFU / dose) and product 3 is a base of Bacillus subtilis1.0x10¹¹ (CFU / g) and Bacillus licheniformis 1.0x10¹¹ (CFU / g). After 60 days, morphological variables were identified as buyer of aerial and root parts, diameter of pseudocaule and bulb, weight of fresh matter and dry material and finally determined the index of galls formed not root system. The results obtained showed that the biomass concentrations between the plants cultivated in soils and with the bioproducts were concluded in comparison with the biomass among the hybrid cultivars of onion cv. 1205 and cv. Serengeti.

About twenty (20) years ago, since graduating in agronomy, the owner of the company Mr. Newton Matsumoto had a purpose when completing the agronomy course at ESALQ, SP, intended to settle in a region to work in the field of fruit growing., becoming a promising agricultural frontier, with a view to improving the region, while also meeting internal and external demands with quality fruits. With this purpose in mind, and the potential for irrigated fruit growing in the sub-region of the São Francisco Valley, mainly due to favorable climatic conditions for the cultivation of various fruit trees. In view of the above, he moved from Paraná State his hometown to Vale São Francisco, Petrolina, PE, with the purpose of operating in this area and growing along with the region. Initially he acquired a seven-hectare property in Senador Nilo Coelho Project, Nucleus 09, in Petrolina-PE, after two years, his father moved to the region to assist him with the vineyards. In early 2001, with the help of his parent, Mr. Newton set up Fazenda Área Nova, with an area of 10 hectares in the Senador Nilo Coelho Nucleo10 Project, in Petrolina-PE. This farm employs about 150 permanent employees in the first semester and in the second semester a larger number of employees, considering that this property has 31 hectares of Palmer mango cultivar and 44.58 hectares of vine, being six grape varieties: Arra 12, Arra 15, Cotton Candy, Midnight, Sugar Crisp and Vitória, with production of approximately 25 tons of grapes per hectare. 80% of grape production is exported to countries such as England, the United States, the Netherlands, Germany, Chile, and serves the domestic market such as the states of Sao Paulo, Rio de Janeiro, Minas Gerais, Paraná, Goiás, among others. The Northeast and North regions stand out for having tropical fruit poles that have shown significant results in recent years, such as those located in the northeastern semiarid, especially in Juazeiro, Bahia and Petrolina, Pernambuco, located in the São Francisco Valley, besides the Mossoró, Rio Grande do Norte, whose main fruits are mango, grape, banana and pineapple and also melon. Irrigated fruit farming is an economic activity of great expression in this city, making it stand out in the whole Northeast region, where grapes and mango are their main productions, besides the fruit growing pole, this region also stands out for its production. of wine and juices.
Análise espaço-temporal da precipitação pluviométrica por Índice de Anomalia de Chuva (IAC) no Sertão de Pernambuco
(2019) Costa, Sidney Anderson Teixeira da; Bezerra, Alan Cezar; http://lattes.cnpq.br/3690303625468223; http://lattes.cnpq.br/3437135530105879
Extreme weather events assume great social and economic relevance, especially in the semiarid regions. The analysis of the rainfall regime of a given region can be done by the Rain Anomaly Index (IAC), which allows understanding and classifying the rainfall regime as to the severity of dry and rainy cycles. The objective of this study was to study the spatio-temporal variability of precipitation in the Sertão de Pernambuco, using the Rain Anomaly Index (IAC) for the climatological normal (1987-2017). For this, rainfall data were obtained from the municipalities of Afogados da Ingazeira, Araripina, Arcoverde, Cedro, Flores, Inajá, Ipubi, Mirandiba, Serra Talhada, Serrita and Sertânia. Annual and interannual precipitation analyzes were performed, negative and positive anomalies were determined throughout the climatological normal and precipitation spatial distribution maps were elaborated in the different annual classifications based on the IAC. The results reveal that in ten of the eleven municipalities studied the rainy season corresponds to the months from January to April. It was found that the years 1993, 1998 and 2012 were the driest in the series, while 1988, 2004 and 2009 were the driest. The number of negative anomalies in the analyzed period was 54.8%, thus showing greater numbers of dry than wet years. It was also found that the Sertão mesoregion has a certain degree of homogeneity in relation to extreme events, i.e., rainy or dry years, when they occur, tend to affect most of the territory. In this work, it was shown that the IAC can be used as a tool to assist climate monitoring and rainfall variability of a given region.

Controlling agricultural pests is a practice that has been undergoing innovations constantly. The use of plant extracts appears as an alternative of pest control and is recommended mainly in family agriculture, and in fields of production mainly in organic agriculture, being a low cost product, easy to obtain and high effectiveness in pest control. The extracts of the plants of MamoneiraRicinuscommunisand CoitéCrescentiacujeteL. are promising in the natural control of pests, as they have toxic substances such as ricin, phenolic compounds and flavonoids, respectively. The objective of this work was to evaluate the effect of the extracts of these plants on the black aphid mortality of the common bean Aphis craccivora(Hemiptera: Aphididae). Mamona and Coité extracts caused a high mortality on black bean aphid with rates of 74.69% and 70.23%, respectively. Comparing the black aphid mortality in the different extracts per day after the application of the extracts, it was verified that the Mamona extract had a higher mortality rate (84.86%) on the first day of evaluation and the second day had a coefficient of 81.3%. However, there was no difference between the plant extracts during the five days of evaluation and they differed from the control throughout the evaluation period, which reinforces the efficiency of the use of these extracts in the control of this pest, as well as the necessity of use of control methods. It is concluded that the plant extracts of Mamona and Coité are efficient in controlling the mortality of black aphid A. craccivoraand contribute to the management of this pest in family agriculture, organic and agroecologicalcrops.

Rice (Oryza sativa L.) is one of the most produced cereals in the world, together with maize and wheat, and when exposed to various adverse conditions, with water deficit, have its productivity compromised. Therefore, the present work aimed to characterize mechanisms indicating damage and oxidative protection that may be present in rice varieties São Francisco, BRS Sertaneja, BRS Primavera and BRS Pepita, when subjected to water deficit conditions. The experiment under greenhouse conditions is divided into three stages. The seeds of the varieties (BRS Sertaneja, BRS Primavera, BRS Pepita and São Francisco in the first phase and BRS Sertaneja and São Francisco varieties in the second and third phase) were disinfected with 5% sodium hypochlorite and sown in four liter pots. . A few days after seedling emergence, nutrient solution applications and biometric analyzes were started. After a certain time, the analysis of gas exchange, physiological and biochemical, as well as grain yield were made. The experiment was conducted in IHD in all stages, except for the first one, arranged in 2 x 2 factorial treatments, consisting of two water treatments (control treatment and water stress). The data of the analyzed variables were submitted to the F test at 0.05 probability and the means compared by the Tukey test at the same significance level. Different behaviors were obtained under optimal conditions due to the different genotypes showing that BRS Sertaneja and São Francisco are more efficient in the use of resources than the others under optimal conditions. In response to water stress, we obtained differences between varieties and between treatments in the same variety, since each one presents degree of sensitivity and response to external stimuli, so that the BRS Sertaneja variety was more resistant to drought and as a better option for use in semiarid region.
Verificação dos tratos culturais para a produção de Macaxeira VAR. Recife e o retorno financeiro do investimento em campos de produção na Aldeia Lama, Cabrobó Pernambuco
(2019) Santos, Fernando Augusto Nascimento; Simplício, Josimar Bento; http://lattes.cnpq.br/1876691945804390; http://lattes.cnpq.br/0250060059047749
Macaxeira is one of the most cultivated crops in Brazil and in the world, it has characteristics that give it a good ease of management, being very resistant to the attack of pests and phytopathological agents. Also not very demanding in relation to the supply of water and high soil fertility rates, all these characteristics make this crop considered one of the most rustic agricultural crops cultivated for food purposes. Knowing how to manage an agricultural crop is not the only factor of importance for success in the agricultural market, another factor that should be taken into account by producers is the issue of production costs, because if there is an investment expected to be profit Satisfactory. The objective was to analyze the production costs and what management adopted in the production process of Macaxeira var. Recife, in Aldeia Lama, Cabrobó-PE. For this purpose, visits were made to the production fields where the stages of preparation, planting, management of infestants, management of insect pests, disease management, harvesting and marketing were carried out. A questionnaire was also applied to the producers, the questionnaire was applied individually, and thus it was possible to carry out a concrete survey of all the costs that had been made from soil till harvest. It is concluded that the cultivation of macaxeira (Manihot Esculenta Crantz var. Recife) in the Aldeia Lama community is a financially viable alternative because it provides good profit margin, even with low technological level of management, productions can be obtained Acceptable. Another important fact is production costs will always vary according to several aspects such as: amount of labor used for planting, infestant plants present on site, amount of labor used in the harvest.

This paper aims to analyze the quality criteria that the backcountry of Moxotó food industry uses for guava production, following the production process from the arrival of the raw material at the industry reception until the guava shipment to the table consumer. The candy goes through several stages until its final product is called: harvest the raw material in the field, clean the guava, send it to the breaker, then pass to the enzymatic inactivator, soon after being sent to the pulp machine and finally is sent to the lung tank. From the lung tank the product goes to the premix, the resulting mixture is sent to the vacuum concentrator. After that, the candy is ready to be filled, which is made by the industry itself with materials that also undergo cleaning and sanitization processes. Products that are not approved for further processing have corrective measures also taken by quality control. Analyzes are performed at company laboratories and other laboratories may be used for other purposes. At the end of guava processing, with all tests signaling product approval, the candy can be safely marketed to the outside consumer.

Information related to reference evapotranspiration (ET0) is very important for irrigation management, especially in regions dependent on agriculture. To determine it several methods can be used, among which are the alternative methods, which are used of few data. This work hypothesized that new models for estimating evapotranspiration and those developed locally better represent ET0 of the Submedio São Francisco. In order to investigate the adequacy of historical and contemporary models for the estimation of ET0 and to develop a new method for its estimation in the region of the Vale do São Francisco. The work was carried out in Juazeiro, Ba, using data referring to a meteorological station belonging to EMBRAPA Semiarid, using data of temperature, relative humidity, wind speed, precipitation and global solar radiation, for the year 2017 and 2018, and for validation of the poposed odel, data from 2016. The data were used in the determination of evapotranspiration using the Penman-Monteith methods and the alternative ones, subdivided into two groups: historical,those developed before theyear 2000with the methods of Hargreaves-Samani, Camargo, Jensen-Haise, Makkink, Solar radiation FAO 24 and Benevides-Lopes, and contemporary, developed afterthe year 2000, with Irmak, Castaneda-Rao, Moretti-Jerszurki-Silva, Silva-Souza, additionally, the information was used in the development of a simple model for ET0 estimation. This information was compared using the indices for which Pearson's correlation coefficient (r), coefficient of determination (r²) and Willmont's concordance index were considered. Based on these results, it was possible to observe that contemporary methods, with the exception of Moretti-Jerszurki-Silva, tended to reduce errors in the estimation of reference evapotranspiration.The most appropriate method to estimate ET0 was the FAO-24 Solar Radiation. The alternative model obtained in the present work was based only on temperature and humidity data and was classified as very good.
