O uso de sistemas agroflorestais traz benefícios ambientais e socioeconômicos, sendo uma ferramenta fundamental para o fortalecimento da agricultura familiar. O plantio de cacau nesse sistema de cultivo encontra no baixo sul da Bahia, condições edafoclimáticas ideais para o seu desenvolvimento. A pesquisa avaliou a viabilidade econômica da implantação de um sistema agroflorestal, com ênfase na produção de cacau, na região do Baixo Sul da Bahia. O trabalho foi conduzido em uma área de um hectare na propriedade do Sr. Valdo Veiga, agricultor familiar de Nilo Peçanha-BA, no período de março de 2021 a fevereiro de 2025. O consórcio do agroecossistema incluiu além do cacau as espécies de açaí, banana-da-terra, gliricídia e mandioca. Numa perspectiva de cinco anos, a pesquisa analisou os custos de implantação e manutenção do sistema, mas também a previsão de receitas e o fluxo de caixa para uma projeção de 20 anos. As análises dos dados usaram indicadores econômicos como o Valor Presente Líquido (VPL), a Taxa Interna de Retorno (TIR) e a relação Benefício Custo (B/C). Os resultados obtidos mostram o custo total do projeto no valor de R$ 95.020,00, e a recuperação do dinheiro investido já no ano 3, totalizando um valor de R$ 101.400,00, demostrando a sua viabilidade financeira. Quando analisado o fluxo de caixa, o sistema agroflorestal pode atingir um lucro de até R$ 87.368,00 /ano, com o cacau e açaí em seu máximo potencial produtivo. Assim, o presente trabalho proporciona informações valiosas para o planejamento e a gestão de sistemas agroflorestais sustentáveis na região, contribuindo para a segurança alimentar, a redução da pobreza rural e a conservação dos recursos naturais.

Brazil is extremely rich in natural resources, being the cradle of plant species of forage interest. As national animal production occurs almost entirely in pastoral systems, which is the cheapest form of animal feed, it is necessary to study forage species adapted to different edaphoclimatic conditions, as well as persistent ones to contribute to the sustainability of production systems animals to pasture. Desmanthus spp and Stylosanthes spp are legumes that occur spontaneously in Northeastern Brazil, with desirable characteristics for cultivation and feeding of ruminants. The objective was to evaluate the morphological and productive characteristics of accessions of Stylosanthes spp and Desmanthus spp from different locations, which make up the Active Germplasm Bank (BAG) of the Federal Rural University of Pernambuco (UFRPE). The plants were cultivated in a greenhouse at the Department of Animal Science and transferred to the BAG / UFRPE, located in the Experimental Station of Sugarcane do Carpina, North wood zone of the state at latitude 7º, 51 '04' 'S, longitude 35º, 14 '27' 'The altitude of 180m in 2017. Variance was observed in all morphological and productive characteristics studied, both for Desmanthus genotypes and for Stylosanthes genotypes, showing the variability between materials and the possibility of being selected superior to the future.

Project coordination is an essential step in the planning of a construction project. This phase will shape all the projects, making the execution more efficient and the planning more aligned with reality. In other words, by coordinating the projects with each other, the budget becomes more aligned with reality, and the timeline and planning proceed as anticipated before the construction begins. This makes the construction more productive, eficiente and with fewer unforeseen events that could interfere with the timeline and budget. This paper presents an analysis conducted on a construction project that was executed with some of its projects coordinated. The budgets were analyzed and compared with the assessment after the project was completed. The productivity of skilled labor was also examined and compared with the data provided by SINAPI (National System of Research and Indices for Civil Construction), revealing significant differences. Additionally, extension studies related to the topic were recommended. It can be concluded from this work that project coordination during the planning phase has a significant influence on the project's final timeline and budget. Moreover, the productivity forecasted by SINAPI cannot be relied upon for planning, as it diverges from the reality of the project.

(2025-03-13) Oliveira, Eduardo Eraldo Alves de; Santos, Mércia Virgínia Ferreira dos; Damas, Luciana Pereira; http://lattes.cnpq.br/1935877952205692; http://lattes.cnpq.br/9565465836878202; http://lattes.cnpq.br/5835511624505718
O capim-elefante [Cenchrus purpureus (Schum.) Morrone] é uma forrageira de alta produção de matéria seca e cultivado em distintas regiões do Brasil. A escolha criteriosa de genótipos para cada sistema de produção resulta na maior eficiência do sistema. O estudo visa avaliar genótipos de diferentes portes para otimizar a produção de forragem, avaliou-se o estabelecimento e desempenho de seis genótipos de capim-elefante sob condições de sequeiro na Zona da Mata Seca de Pernambuco, visando identificar características morfológicas, morfogênicas e produtivas que otimizem a produção forrageira. Foram testados três genótipos de porte alto (BRS Capiaçu, Elefante B e IRI-381) e três de porte baixo (BRS Kurumi, Mott e Taiwan A-146 2.37) durante os 100 dias de período de estabelecimento. O delineamento experimental foi em blocos casualizados, com quatro repetições. Utilizou-se colmos de tamanhos variados a depender do genótipo, 50 cm para os genótipos de porte baixo e 100 cm para os genótipos de porte alto, fracionados, estabelecidos em uma área de 25 m2 com espaçamento de 1 metro entre linhas. A correção de solo foi realizada através de calagem com 2 t ha-1. A adubação de fundação foi realizada com cloreto de potássio e superfosfato simples (120 e 100 kg ha-1). As avaliações morfológicas foram realizadas a cada quinze dias ao longo de um período de 90 dias, enquanto as avaliações morfogênicas foram conduzidas ao final do experimento, após as plantas completarem os 90 dias. As plantas foram colhidas aos 100 dias de estabelecimento, a 5 cm do solo. Foram avaliados altura (cm), comprimento (cm) e diâmetro do colmo (mm), taxa de perfilhamento, taxa de alongamento foliar e do colmo, além da produção de matéria seca (t/ha). A análise estatística incluiu testes de normalidade dos resíduos e homocedasticidade, seguidos de ANOVA utilizando o PROC MIXED do SAS. Os genótipos de capim-elefante foram tratados como efeitos fixos, e os blocos, como aleatórios. Quando o teste F foi significativo (P < 0,05), as médias foram comparadas pelo teste de Tukey, garantindo uma avaliação robusta das diferenças entre os genótipos. Observou-se diferenças significativas entre os genótipos para as variáveis mensuradas. O BRS Capiaçu destacou-se pelo maior crescimento vegetativo, atingindo altura média de 189 cm e maior produção de matéria seca (88,2 t/ha). O Elefante B e o IRI-381 apresentaram valores intermediários, enquanto os genótipos de porte baixo demonstraram maior perfilhamento e maior relação folha/colmo, as quais são características desejáveis para sistemas de pastejo. O Taiwan A-146 2.37 exibiu a maior densidade populacional 15,56 perfilhos/m2, mas apresentou menor vigor e produtividade total de 17,22 t/ha. De acordo com os resultados obtidos, recomenda-se o BRS Capiaçu para sistemas de corte, enquanto os genótipos de porte baixo são mais indicados para o pastejo. Esses dados fornecem suporte técnico para produtores e pesquisadores na seleção de cultivares mais eficientes, contribuindo para o aumento da produtividade forrageira e contribuindo para sustentabilidade da pecuária na região.

(2018-08-24) Vilela, Ávilo Renan Rodrigues; Moura, Mácio Farias de; http://lattes.cnpq.br/1759384860173972; http://lattes.cnpq.br/2393229060826745
Macassar bean is a crop of great socioeconomic importance for farmers in the North and Northeast, where it stands out for its rusticity and adaptation to edaphoclimatic conditions. In its nutritional management aimed at raising productivity, mineral fertilizers of high solubility are used that cause environmental problems such as acidification of the soil and contamination of water courses. The use of organic fertilizers as a source of nutrients, allows to meet the nutritional requirements of plants in a slow and lasting, and use residues that released into the environment would cause strong impacts to it. The objective of this work was to evaluate the effect of the application of the dairy effluent, biofertilizer and inoculant on macassar bean yield. The experiment was installed and conducted at the Experimental Farm of the Federal Rural University of Pernambuco / Garanhuns Academic Unit (UFRPE / UAG). The experimental design was a randomized block design, consisting of nine treatments and three replicates. The treatments were: - T - Absolute Witness; EF - Dairy Effluent; B - Biofertilizer; I - Inoculant; EFI - Dairy Effluent + Inoculant; BI - Biofertilizer + Inoculant; EFB - Dairy Effluent + Biofertilizer; EFBI - Dairy Effluent + Biofertilizer + Inoculant; AM - Mineral Fertilization. The following variables were evaluated: leaf number per plant (NFP), stem diameter (DC), chlorophyll (CLOR), biological yield (RB), dry matter (DM), productivity (PROD), length of pod (CV). The data were submitted to analysis of variance and the means of treatment analyzed by the Dunnett test. Macassar bean yield was higher using mineral fertilizer, organic fertilizers did not favor the increase in macassar bean production.

As an alternative to remedy the impacts caused by the oil shocks of the 1970s, PROALCOOL was a program that was successful in promoting the biofuel ethanol, however, since deregulation, the sugar and alcohol sector has gone through several phases of growth and declines in production, influenced due to various political and market factors. The general objective of this work is to understand and analyze the gross production of ethanol in Pernambuco between 2000 and 2022. To this end, the specific objectives were to describe the historical context of ethanol production in Pernambuco and Brazil, to identify the main factors that influenced production throughout throughout the analyzed series and understand the relationship between price, sales and productivity with ethanol production. As a methodology used, a bibliographical review, graphical analyzes and descriptive statistics were carried out. The research results showed that ethanol production in Pernambuco over the last few decades has been influenced by several factors and that despite the measures adopted by the government to stimulate the sector in recent years, it still faces challenges in ensuring continuous and competitive growth. to consumers. Justifying that it is essential to understand the policies adopted for ethanol and their impact on the market and society. The historical analysis of these policies and their results can contribute to the development of new strategies for the future.

(2023-04-13) Batista, Arthus Douglas; Mélo, Ralini Ferreira de; http://lattes.cnpq.br/4296426234246190; http://lattes.cnpq.br/2013424295271323
Water is one of the main factors for agricultural production and one of the most used parameters to evaluate the irrigation system is the uniformity of the application of the water layer over the irrigated area. This work was carried out with the objective of evaluating the productivity of the common bean (Phaseolus vulgaris L.) cv. Carioca due to different levels of uniformity simulated using Solver, which is a software for mathematical programming integrated into an electronic spreadsheet (Excel). The Keller & Karmeli (1975) model was used as a reference for simulations of the water depths of a system with drip irrigation and the productivity was estimated according to the methodology proposed by Figueredo et al. (2008). As a result, the highest mean depth value (568.1 mm) and lowest productivity (1991.3 kg ha-1) of the common bean crop were obtained for the system that presented a CUC of 65%. On the other hand, the lowest mean depth value (416.4 mm) and highest productivity (2981.1 kg ha-1) were obtained for a system with 95% CUC. In a direct comparison, a 26.7% reduction in the mean blade value and a 49.71% increase in productivity were noted, thus confirming that a system with greater uniformity is more efficient.

(2022-06-06) Silva Júnior, José Santino da; Silva, Manassés Mesquita da; http://lattes.cnpq.br/2249840331584869; http://lattes.cnpq.br/7667530223951004
Given the importance of irrigating agricultural crops, it is necessary to determine the uniformity of water distribution to ensure the quality of irrigation, frequent monitoring of irrigated areas must be carried out in order to observe the dynamics and conditions of cultivation. In view of this, the present work was developed with the objective of evaluating the quality of irrigation of sugarcane at Usina Vale Verde - Baia Formosa. The study was carried out between February 2021 and February 2022, at Fazenda Pedrosa, belonging to Usina Vale Verde and located in the municipality of Bahia Formosa-RN. A total area of 15 ha was used, subdivided into five sectors of 3 ha each. At the end of the sugarcane cycle, for each of the sectors, the irrigation system flow uniformity coefficient (CUD) and crop productivity were determined. In addition, in six seasons throughout the crop development, the mapping of the Normalized Difference Vegetation Index (NDVI) of the soil cover was carried out, through the QGIS software, using Sentinel-2 satellite images made available by the spatial database of the United States Geological Survey (USGS). The NDVI determination was performed by the ratio between the reflectance difference of the near infrared (band 04) and red (band 08) bands, under their sum, the NDVI images were classified according to the vegetation cover density in phytophysiognomies. After evaluating the data obtained in the present study, it was found that the CUD values have a direct correlation with the productivity of the place, as well as the NDVI images showed higher values in the areas of greater CUD and productivity, thus, the CUD and NDVI are important variables as a source of information in decision making in improving irrigation quality.
