Ácido giberélico na conservação pós-colheita de frutos de umbuzeiro (Spondias tuberosa Arruda Câmara) em condição refrigerada
(2019-07-09) Oliveira, Francisco Jardel Moreira de; Ataíde, Elma Machado; http://lattes.cnpq.br/2422663252620574; http://lattes.cnpq.br/7543700066092948
The umbuzeiro is a native species of Caatinga, it has as fruit the umbu, with great social and economic importance for the Northeastern region of Brazil. The umbu has great acceptance in the market for in natura consumption and of products such as popsicles, jellies and sweets, however, the absence of post-harvest technologies to preserve this fruit causes that much of the harvest is lost. An alternative to increasing the shelf life of umbu is the use of refrigeration associated with regulators such as gibberellic acid (GA3), which acts to reduce the rate of respiration and inhibit the synthesis of ethylene in post-harvest. In this sense, the objective of this study was to evaluate different concentrations of GA3 in the post-harvest conservation of umbu in refrigerated conditions, based on the attributes of fruit quality. The fruits were harvested manually at maturation stage " for once", immediately washed and sanitized in 2% (w/v) sodium hypochlorite solution, dried in ambient condition and selected for size, appearance and physical damage. Then, the following treatments were performed: T1: 0 mgL-1 (Witness), T2: 10 mgL-1 of GA3, T3: 20 mgL-1 of GA3 and T4: 30 mgL-1 of GA3. The fruits were immersed for 60 seconds, dried in ambient condition and conditioned in refrigerated condition. The experimental design was completely randomized, with plots subdivided in time, the plots consisted of the four concentrations of GA3 and the subplots for storage time (0, 5, 10 and 15 days), except for mass loss, with evaluation three days. Five replicates with 5 fruits were used for each subplot, totaling 100 fruits per plot. The data were submitted to analysis of variance and when significant, the Tukey test was applied at 5% for the concentrations of GA3 and the regression analysis to the subplots. The attributes of quality evaluated were: length, diameter and shape of the fruit; weight loss; weight and yield of pulp; fruit mass, bark and seed; yield of pulp and seed; soluble solids, titratable acidity; pH; ratio and technological index. The concentrations of gibberellic acid did not present significant interference with the physical attributes of umbuzeiro fruits in refrigerated conditions, except for pulp mass and pulp yield, which presented the best results for GA3 20 and 30 mgL-1 concentrations. The weight loss of the fruits did not differ from the control among the applied treatments, being the highest loss obtained in the concentration of 30 mgL-1 of GA3. The storage time was the factor of greater interference on the physical-chemical attributes, however, for the ratio, there is interference of GA3 concentrations up to the 10th day of storage. There is a need for further investigation regarding the use of GA3 in the post-harvest conservation of umbu, with test of other concentrations and immersion time in order to prove the efficiency of this regulator in the maintenance of post-harvest life of umbu in refrigerated condition.

Adubação nitrogenada como atenuador do estresse salino em algodão colorido: uma revisão de literatura.
(2021-11-29) Souza, Jamiles Carvalho Gonçalves de; Oliveira, Alexandre Campelo de; http://lattes.cnpq.br/8164135937542569; http://lattes.cnpq.br/8445795289858316
Cotton is a crop of great economic prominence on the world stage. The commercialization of its fiber in the textile industries, the use of its seeds as raw material in the production of animal feed and vegetable oil, highlights it as one of the most profitable annual crops in the agricultural environment. In Brazil, the Northeast region is one of the largest producers of this crop, with emphasis on the production of colored cotton, where its cultivation is of paramount importance mainly for family farming, and these are the main producers of this fiber. However, the semiarid region has high temperatures and low rainfall concentrated in three months of the year, as a result of which droughts end up occurring more frequently, thus limiting agricultural and livestock activities in the region. The use of irrigation systems helps to increase productivity, however, due to the low quality of water from a high content of salts present in it, there is a metabolic stress that ends up harming the growth and development of crops. In an attempt to alleviate the damage caused by saline water, producers and farmers opt for the use of crops that are more resistant to salinity and even for fertilization techniques, with nitrogen being one of the most used nutrients, as it is required by most agricultural crops. In this sense, the objective was to carry out a literature review to evaluate the effect of different doses of nitrogen and saline water irrigation during the production of colored cotton in the Brazilian semiarid region. Data collection took place on websites of journals and scientific communities, with articles published in Portuguese, English andSpanish, in the areas of plant production and plant nutrition. The deleterious effects caused by the salinity of the irrigation water in the culture of colored cotton for the semiarid region were analyzed, and which nitrogen doses provide a better cotton production under these conditions. Therefore, it is of paramount importance to propagate research information, in the form of articles,on this subject.

(2019) Cirino Júnior, Baltazar; Leite, Maurício Luiz de Mello Vieira; Oliveira, Alexandre Campelo de; http://lattes.cnpq.br/8164135937542569; http://lattes.cnpq.br/4204641633941814; http://lattes.cnpq.br/4245406622322251
The objective of this study was to evaluate the agronomic performance of Nopalea cochenillifera clones under different levels of potassium. Cladodes of forage palm were selected and collected (in the middle third of the plant), which was three years old, in the UAST experimental area. These cladodes went through a healing period of 10 days. They were then placed in pots (larger diameter) = 24 cm (smaller diameter) = 17 and 23 cm deep), with a capacity of 7 kg of soil, presenting deep drains, covering the bottom of the vessel with gravel to facilitate drainage. The experiment was arranged in a randomized block design in a 5x2 factorial scheme, using five levels of potassium (0, 250, 500, 750 and 1000 Kg.ha-1) and two forage palm clones (Giant Sweet and Sweet Child), with four replicates. Five biometric campaigns were carried out in August, September, October, November and December / 2018 to measure the plant height, length, width and thickness of cladodium, as well as the number of cladodes in order and totals . For the comparison test of means, only the data of the last campaign were used. The clones presented a similar response to potassium fertilization, presenting non significant results for fertilization levels. When comparing the two clones, there was no significant difference for all studied variables: plant height, number of cladodes, length, width and thickness of cladodes. Potassium fertilization does not influencethe morphological, productive and potassium parameters of plant tissues during the initial growth of the genus Nopalea. The software used was R-project version 3.5.0 and SigmaPlot 10.0.

Colored cotton has great social and economic importance for the Northeast region. It is important socially to favor the permanence of the man in the field, reducing the rural and economic exodus, due to the greater appreciation of the naturally colored fiber, around 39 to 78% more than the white fiber, leading to greater profitability. The objective of this study was to evaluate the behavior of the BRS Verde colored cotton cultivar to the use of different doses of mepiquat chloride. The experimentwas conducted in a greenhouse between August and December 2018 at UFRPE / UAST, PE. The statistical design was completely randomized, where the treatments resulted in the application of 5 doses of growth regulator based on mepiquat chloride -0,0; 0.07; 0.14; 0.21; 0.28 Lha-1 and 4 replicates. The obtained data were submitted to analysis of variance and when verified the significant effect they were submitted to the analysis of polinomial regression through the Sivar software. Variations of plant height, distance between nodes, number of nodes, stem diameter, leaf area, dry shoot mass, root dry weight and total dry mass, height of first flower bud, height of first flower insertion , number of flowers, number of apples, number of beaks per plant, beet mass, fiber production and seed cotton production. The use of mepiquat chloride in BRS Verde colored cotton provided similar behavior in the plants that received application of the product, however when compared to the control plants there was a difference between them. The productive parameters of the BRS Green cotton are reduced with the use of mepiquat chloride from the dose of 0.07 L.ha-1 and tend to decrease simultaneously as the doses of the growth regulator are intensified. With regard to the analyzes of phytomass of shoot and root, with the application of mepiquat chloride in the BRS Verde cotton cultivar, the average values obtained were obtained, resulting in larger masses for the treatments used.

Soils are the result of the action of factors and processes that operate at different intensities and cause various changes in their characteristics, so a systematic study of these changes is important to understand soil genesis. Soil surveys are an inventory of their characteristics, as well as their geographic distribution within the area and their taxonomic classification. In the Sertão of Pernambuco, the basic studies of soils, carried out by the Ministry of Agriculture(MA), began in 1957. This survey aimed at identifying and studying the soils existing in the State, however new nomenclatures for Brazilian soils were adopted and published by Embrapa through the edition of the Brazilian Soil Classification System (SiBCS), the last version of which was published in 2018, so the objective of this research was to identify alterations and to reclassify soils located in the backlands of Pernambuco described in the Exploratory Survey -State Soil Reconnaissance of Pernambuco, using the updated Brazilian Soil Classification System. Three profiles described in the above survey were selected for analysis. A comparison of the information described in the survey with those obtained in the field was carried out, as well as an evaluation of the relationship between the physical and chemical characteristics of the soils surveyed with the source materials of these soils (rocks) collected in the field together with the samples of ground. For the physical (granulometry) and chemical analysis of the soils, the Embrapa methodologies were adopted and in parallel the minimololites were made with the soils studied. It was verified that the small changes are due to the variation of the original material, to the handling, the relief and the location of the final profiles not to be exactly the same as the initial profiles. In spite of the variation, the three final soils met the prerequisites to remain in the same Order of the initial soils, classified as NEOSSOLO QUARTZARENICO, LUVISSOLO and LATOSOLO.

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.
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.

Aspectos do crescimento da Baraúna (Schinopsis brasiliensis Engel.), em diferentes contextos de intervenções antrópicas, na comunidade da Mata Redonda em Triunfo – PE.
(2022-05-27) Santos, Natália Alves; Barros Júnior, Genival; http://lattes.cnpq.br/4379675294862211; http://lattes.cnpq.br/4530134000429562
The Caatinga vegetation has a very peculiar characteristic, which makes it unique and, unfortunately, due to anthropic actions, a considerable portion of this biome is in extinction and another portion is threatened with extinction. Among the endangered plant species is the Baraúna (Schinopsis brasiliensis Engl.), one of the most important trees in the Caatinga, considered a noble tree due to the characteristics present in its wood. Given this situation, research actions aimed at preventing the extinction of the Baraúna species are shown to be of great importance for the preservation of biodiversity in the Caatinga Biome. However, there are still few studies aimed at rescuing and protecting the dynamics of this important species in the Caatinga vegetation. Thus, the objective of the present work was to study the initial behavior and to relate the growth rates of Baraúna plants introduced in areas under different impacts arising from agricultural management over time in environmental conditions of high-altitude swamp. 10 The experiment was carried out in a Random Block Design - DBC, in an 11 x 3 arrangement (11 baraúna plants in 3 different areas of human intervention) area 1- degraded soil; area 2- arable soil; area 3- agroforestry system, carried out from October 2021 to March 2022. Soils were collected for analysis, rainfall data, luminosity data, soil cover and monthly biometric readings. In area 1, the soil was classified as sandy clay, compacted, low rate of living and dead cover, accentuated presence of erosive processes, high presence of luminosity and average growth of baraúnas when compared to the other areas; area 2- clay soil, compacted, high presence of living cover, medium presence of mulch, presence of erosive processes, high level of luminosity and it was the area in which the plants showed the highest growth in terms of stem diameter as in vertical growth; and in area 3 soil classified as sandy clay loam, not compacted, high index of living and dead cover, punctual erosion processes, low luminosity and slow growth of baraúnas. The baraúna plants are demanding in light, requiring full exposure of the canopy of their canopy to solar radiation to ensure a satisfactory development of the individuals of their species. The reintroduction of the species Schinopsis brasiliensis in the ecosystem of highland swamps is recommended due to its ecological, environmental and anthropological importance for the enrichment of local biodiversity.
Aspectos fisiológicos de sementes de Piptadenia moniliformis Benth
(2019) Silva, Joyce Naiara da; Silva, Monalisa Alves Diniz da; http://lattes.cnpq.br/0446410743186066; http://lattes.cnpq.br/3432689640499564
With the increasing demand for seeds of high quality native forest species, mainly to support the work of mixed reforestation, it is fundamental that the methods of quality evaluation of the seeds are efficient, so the present work aimed to evaluate aspects pertinent to the physiological quality of seeds of Piptadenia moniliformis Benth. (calico angus). Two experiments were carried out: experiment 1 -Use of seed dormancy overcoming treatments, where they were immersed in concentrated sulfuric acid by (zero -intact seeds, 5, 10, 15, 20 and 25 minutes). The design was a completely randomized design, with six treatments and five replicates of 20 seeds per treatment. Experiment 2 -Evaluation of the methodology of the accelerated aging test, that is, traditional methodology and that employing the use of saturated NaCl solution at 41ºC with periods of zero exposure; 24; 48; 72 and 96 h. Before and after each aging period, regardless of the method, the water content of the seeds was determined. After each treatment the seeds were submitted to electrical conductivity and germination tests. The design was completely randomized, in a 2x5 factorial scheme (methodology x exposure times), with four replicates of 25 seeds per treatment. To overcome seed dormancy there was no statistical difference between the times of 5; 10; 15; 20 and 25 minutes of immersion in sulfuric acid, but the time of 20 minutes provided a larger number of seeds with protrusion of the primary root. The different methods of accelerated aging, conventional and saturated solution, affected the physiological quality of seeds of Piptadenia moniliformis Benth., With the reduction of the germinative potential after 24 hours of exposure. Regarding the methodology employed, the use of the saturated solution generally gave the best results, as the water content of the seeds was lower, thus reducing fungal growth. The results obtained in the biochemical test of electrical conductivity showed that the increase of the aging period, independent of the methodology, caused the increase of the deterioration of the seeds. It is soon concluded that the seeds of P. moniliformis Benth. had their dormancy overcome when immersed in concentrated sulfuric acid for periods of 5; 10; 15; 20 or 25 minutes; and that the different methodologies of accelerated aging, traditional and saturated solution, affected the physiological quality of the seeds.

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.

Cowpea (Vigna unguiculata (L.) Walp.) has its center of origin located in the African continent, being introduced in Brazil around the 16th century and is still recognized today as one of the most consumed legumes in the North and Northeast regions. Its cultivation is expressive by irrigating farmers, however, the water used is of poor quality and extremely saline. This salinity can affect the absorption of nitrogen, an important macronutrient for the growth and development of the legume and associating with this condition the deficiency of molybdenum, an important micronutrient in nitrogen metabolism, which together can be an important nutritional management strategy to provide the expression of maximum productive potential of cowpea. The objective of this work was to evaluate the behavior of cowpea cv. IPA 207, when subjected to increasing doses of molybdenum associated with nitrogen doses, aiming to establish the treatment that would enable the best increment of the studied variables. The experimental design used was in randomized blocks, generating a factorial scheme, 5x2x4, totaling 40 experimental units, with the following treatments: 5 doses of molybdenum (0, 40, 80, 120 and 160 g/ha) and two doses of nitrogen ( 0, 80 kg/ha) and 4 repetitions. The molybdenum source used was sodium molybdate, and urea was nitrogen. Treatments were applied 23 days after seedling emergence. The variables studied were: plant height (cm), stem diameter (mm), number of pods per plant, number of grains per pod, mass of one hundred grains (g), fresh and dry mass of shoot (g), fresh and dry root mass (g) and the activity of the nitrate reductase enzyme. The data obtained were submitted to analysis of variance and then to polynomial regression analysis. The increasing doses of molybdenum applied via the leaves in association with nitrogen fertilization positively influenced the activity of the nitrate reductase enzyme, as well as the accumulation of fresh and dry matter of cowpea, in addition to the significant increase in the variables number of grains per pod and number of pods per plant.

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.

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.
