Item Qualidade sanitária de sementes de capim buffel (Cenchrus ciliaris l.) comercializadas nos municípios de Afogados da Ingazeira, Flores e Calumbi no Sertão do Pajeú(2022-05-23) Araujo, Rafael Pereira de; Albuquerque, Neilza Reis Castro de; http://lattes.cnpq.br/5706869625614564; Não localizadoThe seed is the main disseminator of diseases and the lack of knowledge of the sanitary state of the lot can bring several losses in the establishment of the crop. For buffel grass there is a scarcity of works that inform the sanitary quality of plots sold in Sertão do Pajeú. Thus, the objective was to evaluate the phytosanitary quality of Cenchrus ciliaris seeds commercialized in Sertão do Pajeú. The grass buffel seeds were acquired from the trade and directly from the producer in three municipalities in the region. The batches of seeds sold at home farming were acquired from the municipalities of Afogados da Ingazeira and Flores, harvested in the 2021 crop, the seeds purchased directly with the product came from the municipality of Calumbi, harvested in the 2022 crop, from each municipality it was obtained a batch containing 1 kg of seed, followed by a sanity and germination test. To evaluate the health of the seeds, the filter paper method was used. A total of 200 seeds were used from each randomly chosen lot and arranged in a completely randomized design. Prior to the test, the seeds were disinfected in sodium hypochlorite solution (1.5%) for 2 minutes and 30 seconds in 70% alcohol, the 200 seeds were divided into 10 petri dishes containing a sterile and moistened filter paper (20 seeds / board). The seeds were incubated for eight days at room temperature and under alternating light (12h light/12h dark). At eight days of incubation, they were analyzed for fungal incidence through visual analysis and plating, germination with counting the number of germinable seedlings. The data obtained on fungal incidence and germination were transformed into √(x+0.01), the means of the lots were statistically compared by the Scott-Knott test at 5% probability by the SISVAR program. It was observed that the seeds sold in the municipalities of Afogados da Ingazeira and Flores presented fungal contaminants. The batch from Calubim did not show the presence of contaminants, the presence of bacteria was also observed in the test performed. In the batch of seeds of Afogados da Ingazeira the genera Fusarium, Penicillium, Mucor and Trichoderma were detected in high incidence, for the batch from the municipality of Flores the genera Penicillium and Alternaria were detected in high incidence. The fungal incidence was higher in the batch of Afogados da Ingazeira with 50% of the seeds contaminated. Regarding germination, there was no significant difference at 0.5% probability by the ScottKnott test for three cities studied.Item Produtividade, estresse e proteção oxidativa em feijão-caupi inoculado com estirpes de Alfa e Beta-Rizóbios(2022-05-27) Martim, Mayara Bernardo Tavares; Simões, Adriano do Nascimento; http://lattes.cnpq.br/1895049701533568; http://lattes.cnpq.br/1861408621908918Item 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/4530134000429562The 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.Item Perfil dos consumidores da Feira da Agricultura Familiar de Triunfo – PE(2022-05-24) Oliveira, Jéssica Patrícia de; Almeida, Rosa Honorato de; http://lattes.cnpq.br/4319299572657528; http://lattes.cnpq.br/4377561093655050Agroecological Fairs have an indispensable role in safe and healthy food as they provide the supply of different types of products for consumers while guaranteeing the family income of several farmers. The present study aimed to identify the profile of consumers of agroecological products in the city of Triunfo-PE, as well as their satisfaction with the products sold. Data collection was carried out using forms available at the Feira da Agricultura Familiar de Triunfo. The data obtained were tabulated and processed in a Microsoft Excel 2010 spreadsheet. Through the results, the consumer profile was identified and, based on the Net Promoter Score (NPS) methodology, the consumer satisfaction and preference index. Through this study it was possible to identify the profile of people who usually attend the fair, which is mostly composed of women and young people. Through the NPS it was identified that the fair is located in the improvement zone, an area close to the quality one, which indicates a good performance of the agroecological fair in the city. With the application of a form containing open questions, information was collected, which are of paramount importance for the development of possible improvement plans for the fair. Such results proved to be effective in identifying positive and negative points and, therefore, actions that can increase consumer satisfaction, as well as their quantity, are appropriate.Item Trocas gasosas, massa fresca e qualidade de água no cultivo do gergelim associando cinzas do bagaço de cana-de-açúcar e água salina(2022-05-25) Ramos, David Gleidson Moreira; Lira, Raquele Mendes de; http://lattes.cnpq.br/7303795378184706; http://lattes.cnpq.br/3746280840837783Irrigated perimeters are intended to minimize problems related to drought. In the Northeast, in line with the availability of water, some factors affect the quality of irrigation, such as salinization, which commonly occurs in water from wells located in sedimentary soil in the semi-arid region. Due to the climate and the characteristics of the aquifers, brackish or saline waters affect not only the physical and chemical parts of the soil but also the growth and development of the plant, its nutritional and physiological aspects. Therefore, it is necessary to introduce innovative management techniques aiming to maximize agricultural production and simultaneously reduce the effects of salinization. However, the use of organometallic fertilizers such as vegetable ash can reduce acidity and provide better soil fertility. Sesame is considered a salinitysensitive crop, on the other hand, the climate of the semi-arid region favors its production, making it a source of income for farmers. In this sense, the objective was to evaluate the effects of different dosages of ash from sugarcane bagasse and irrigation with saline water, evaluating gas exchange, dry matter, and water quality of sesame in the semi-arid region of Pernambuco. The study was conducted at the Federal Rural University of Pernambuco at the Serra Talhada Academic Unit (UFRPE/UAST), using the experimental design in randomized blocks in a factorial scheme ((5 x 2) +2), with 4 replications totaling 48 experimental units. The treatments consisted of five doses of sugarcane bagasse ash (0, 30, 60, 90 and 120 g.plant-1), two water qualities (A1= Public supply water (0.5 dS m -1); A2 = Artesian well water (4.1 dS m-1) and two additional controls (T1 = Recommended fertilization + public supply water; and T2 = Recommended fertilization + artesian well water. The experimental unit was represented by nine plants, but for physiological analysis, only one plant was used. The net assimilation of CO2(A), stomatal conductance (gs), the internal concentration of CO2 (Ci), and transpiration (E) were analyzed, and the readings were carried out 70 days after sowing. In addition, the water use efficiency (USA) and carboxylation efficiency were determined. At 90 DAS, the harvest was carried out and the fresh plant matter was measured. pH and electrical conductivity of the soil saturation extract. The data were submitted for analysis of variance by site F at 1 and 5% probability. Due to the rains during the experiment, it was not possible to state whether the ash dosages could affect the effects of salinization on gas exchange in sesame. The highest ECs were found in soil irrigated with brackish water and the use of mineral fertilizer provided a higher yield of fresh matter than treatments that received only ash from sugarcane bagasse as a source of fertilization.Item Diagnóstico ambiental por índices de vegetação no Parque Estadual Mata da Pimenteira no período chuvoso e seco(2022-05-23) Rocha, Alessandro Higor Gomes da; Bezerra, Alan Cézar; http://lattes.cnpq.br/3690303625468223; http://lattes.cnpq.br/1372320248183121Due to the monitoring needs, as well as the understanding of the vegetation conditions of the Mata da Pimenteira State Park, it was aimed to analyze vegetation indices generated with red and infrared bands, with Sentinel-2 images to verify the land cover in the rainy and dry period from 2016 to 2021. The study site is located in the municipality of Serra Talhada, Pernambuco. The images were processed in Google Earth Engine to obtain a composition of the two periods studied, then, in QGIS software version 3.18.3 (Zurich), the vegetation indices (NDVI and VCI) were determined by raster calculator, a calculation tool available in Qgis that uses as a basis the values of the pixels of the layers. After obtaining the indices, the descriptive statistics of the images were obtained and classified using the r.recode tool, with subsequent counting of the vegetation classes by r.report, so that from this, the thematic map for the analysis and diagnosis of the study area was made. The results indicate higher average NDVI for 2016 and 2017 with 0.7 in the rainy period, and 0.36 in the dry one. The VCI had its highest average in 2016 with 86.04 and lowest in 2018 with 63.63. In the rainy period more than 90% of the area was composed of the high vegetation density with the NDVI and VCI of the very light class. In the dry period, most of the area was of the class "low vegetation density" by NDVI and "severe" by VCI.Item Levantamento fitossociológico de plantas invasoras em cultivos de palma forrageira e milho(2022-05-27) Gomes, Victor Henrique de Lima; Almeida, Rosa Honorato de; http://lattes.cnpq.br/431929957265752; http://lattes.cnpq.br/3972659364735180Research related to the identification of invasive plants is so far unknown for the culture of cactus in the semi-arid northeast. Therefore, the present study aimed to evaluate the weed community under different cultivation conditions through a phytosociological survey. The experiment was carried out in an experimental area located at the Universidade Federal Rural de Pernambuco, which has been cultivated with forage cactus (Orelha de Elefante Mexicana) and vip ferocious hybrid son, distributed in six treatments: exclusive cactus with and without mulch; palm intercropped with corn with and without mulch; and the condition of exclusive corn with and without mulch. Based on the data obtained, the following phytosociological parameters were calculated: frequency; relative frequency; density; relative density; abundance; relative abundance; and the importance value index. There was a need for greater attention in the area for the management of the poaia-rasteira (Richardia grandiflora (Cham. & Schltdl.) Steud.), which obtained the highest frequencies and importance value index in most conditions of cultivationItem Contribuição da condutância estomática de grupos funcionais de plantas lenhosas na condutância do dossel em vegetação de Caatinga(2022-05-23) Jesus, Angela Lucena Nascimento de; Lima, André Luiz Alves de; http://lattes.cnpq.br/3425654823765293; http://lattes.cnpq.br/3432981548836565The arboreal species of semiarid regions contribute in different ways to the cooling of the canopy, considering the diversity of species and functional groups of plants. Although the vegetation-atmosphere relationship is important from the point of view of climate change, studies evaluating the contribution of caatinga functional groups to the canopy conductance are still scarce. The objective of this study was to evaluate the relation of the stomatic conductance of different functional groups of plants with the conductance of the canopy in Caatinga vegetation. The work was carried out in an area of the Caatinga, located in Fazenda Buenos Aires, Serra Talhada- PE. Two species of high wood density (WMD) and two species of low wood density (WDL) were evaluated. The meteorological data were obtained from a micrometeorological station installed in the study area and the canopy conductance was calculated. The stomatic conductance, leaf temperature and hydrous potential of xylem were evaluated. Stem samples were collected and anatomical structures of the xylem were measured. Analysis of variance of repeated measures and Tukey test with p < 0.05 were performed. Functional groups contributed differently to the canopy conductance. There was a positive relation of the canopy conductance and stomatal conductance (0.761). In the initial rainy season, the canopy conductance was 0.003 m s-1 , with the largest contribution to the canopy conductance occurring by the WMD species (150 mmol m-2 s -1 ). In the rainy season the species' stomatal conductance increased for WMD (100 to 300 mmol m-2 s -1 ) and WDL (200 to 300 mmol m-2 s -1 ). The canopy conductance also increased during the rainy season (0.02 and 0.05 m s-1 ). The water potential was higher for WDL (-1.2 MPa) and lower in WMD (-2.5 MPa) species. The WMD species presented greater amount of xylem vessels (58 mm-2 ) and wall thickness (16 ), and smaller diameter of the lumen of the xylem vessels (140 ). The WDL presented thin wall (9 ) and smaller amount of vessels (5 mm-2 ). These results show that, WMD species have strategies that favor the canopy conductance, even in the dry season, while WDL are more conservative and contribute to the canopy conductance in the rainy season. This study clarifies the importance of functional diversity for maintaining water and environmental balance in semi-arid regions, such as the Caatinga.Item Modificação do uso da terra e seus impactos sobre o fósforo e carbono orgânico do solo no semiárido de Pernambuco(2021-11-26) Silva, Luiz Filipe dos Santos; Pessoa, Luiz Guilherme Medeiros; http://lattes.cnpq.br/1540664578909440; http://lattes.cnpq.br/5391115086399833In the Pajeú sertão, a semiarid region of Pernambuco, the deforested areas of caatinga are intensively used for agricultural cultivation until they deplete soil nutrients such as phosphorus and carbon. until exhausted, and after intensive use of the soil, these areas are abandoned and/or used for grazing animals. Thus, this work aimed to evaluate the dynamics of phosphorus and soil organic carbon under different conditions of land use, in the semiarid region of Pernambuco. Samples were taken in layers of 0-5, 5-10, 10-15 and 15-20 cm of soil under different land use situations: degraded pasture, regenerating caatinga and preserved caatinga. To characterize the chemical attributes of the soils, pH in water (1:2.5), exchangeable cations (Ca2+, Mg2+, Na+ and K+ ) were analyzed, in addition to available phosphorus and organic carbon. The evaluations showed a decrease in the phosphorus content of the surface layer, which was due to the processes of soil degradation generating a lack of nutrients, and the phosphorus content is being made available in the soil as there is a decrease in the levels of Na+ , Mg2+, pH and CTC. Therefore, the degradation of the area and land use without proper management provided an increase in Ca2+ and Mg2+, interfering with the availability of organic carbon, with a high CTC in the three areas. The pH and sodium showed a negative correlation, thus showing an increase in organic carbon as the area is preserved and a decrease with degradation. So, we warn that inadequate soil management can contribute to the loss of important nutrients to the soil such as phosphorus making it unavailable to plants and organic carbon, so it is important to emphasize that many years are needed for the recovery of phosphorus and organic carbon contents, this highlights the importance of preserving native vegetation in the semiarid region of Pernambuco and other northeastern states that belong to the caatinga biome.Item 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/8445795289858316Cotton 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.
