This study evaluated the production and physiological quality of seeds from six lima bean genotypes, cultivated in São Luís – MA, as a function of seed inoculation with Bradyrhizobium japonicum and the application of different levels of organomineral and foliar nutrition. The study was designed in a factorial scheme, using five management treatments (T1: Control without inoculation/without fertilization; T2: Not inoculated + Organomineral Fertilization; T3: Inoculated + Organomineral Fertilization; T4: Inoculated + Foliar Fertilizer; and T5: Inoculated + Organomineral Fertilization + Foliar Fertilizer) applied to different genotypes, cultivated in intercropping with maize. The treatments aimed to maximize biological nitrogen fixation (BNF) and provide essential micronutrients (boron, manganese, molybdenum), optimizing plant physiology. After harvest, the produced seeds were subjected to productivity analyses (kg/ha), thousand-seed weight, and physiological potential tests (germination, first count, and germination speed index). The results demonstrated that nutritional management and inoculation with Bradyrhizobium positively impacted productivity, especially in genotypes that showed a greater symbiotic and nutritional response, surpassing the performance of the control. The combination of inoculation with organomineral fertilization (T4) tended to result in seeds with greater vigor and mass, indicating better translocation of photoassimilates to storage organs. The evaluated P. lunatus genotypes showed uniformity regarding the physiological quality of seed germination, regardless of the treatment. The "orelha de vó" and "fava cearense" genotypes show greater vigor, according to the seedling germination speed index and an increase in the mass of one thousand seeds when subjected to inoculation with Bradyrhizobium associated with organomineral fertilization Thu, 18 Dec 2025 00:00:00 GMT https://repositorio.uema.br/jspui/handle/123456789/5865 2025-12-18T00:00:00Z https://repositorio.uema.br/jspui/handle/123456789/4631 Título: Uso de organominerais na severidade de mancha alvo e ferrugem asiática em soja Abstact: Soybeans (Glycine max L. Merrill) feature prominently in Brazilian grain production, playing an important socioeconomic role in the country. However, its productivity is affected by several diseases, with target spot and Asian rust being among the main ones. The objective was to evaluate the use of organominerals on the severity of diseases. The experiment was conducted in the field in the municipality of Balsas (MA). Two soybean cultivars were used (BRASMAX Bônus IPRO and BRASMAX Olimpo IPRO). A randomized block design was adopted, arranged in a subdivided plot scheme, in the subplot there were three phosphate fertilizers [two of which were organominerals, and one phosphate fertilizer (simple superphosphate)]. And, in the subplot, doses of 0 (control), 50 and 100 kg of P2O5 per ha-1 containing 7 treatments. Disease severity assessments took place 7 days after the first, second and third application and 7, 14 and 21 after the fourth. At stage R6, defoliation was assessed and at the end of the cycle, harvesting was carried out to determine productivity. The variables analyzed in the soybean cultivars were not influenced by the doses of organominerals. However, the BMX Bônus cultivar, when receiving the treatment, 100 kg of P2O5 per ha-1 of ORG1 presented higher PMG values than the other treatments. Soils with high phosphorus levels, the absence of fertilization, control treatment, or the use of fertilization with organominerals, promoted higher productivity in the BMX Bônus cultivar, in which the treatment, with doses of 50 kg of P2O5 per ha-1 of ORG1, resulted in greater productivity.

The aim of this study was to evaluate the effect of the application of doses of the amino acid-based biostimulant (Stopping Go®) applied at different stages of vegetative development of cowpea on the yield and lodging components. The study was conducted in an irrigated field at the ACCERT Experimental Station - Piquizeiro Farm, in Balsas/MA. The experimental design used was randomized blocks, in a 5x2 factorial scheme, using 5 doses of the products (Stopping Go® at doses of 0; 125; 250; 500 and 750 mL ha-1) and 2 development stages (V2 and V4), with 4 replicates, totaling 40 plots. The applications occurred at the study stages of the cowpea cultivar BRS Guariba. Plant height, lodging, and injury (phytotoxicity) were assessed at 7, 14, 21, and 28 days after each application (DAA) of Stopping Go®. At harvest, branching, number of pods per plant, number of grains per pod, thousand-grain weight (PMG), and productivity were assessed. After obtaining the data, they were subjected to Statistical Analysis of Variance (ANOVA), and for variables that presented significant differences, the F test was performed at a 5% probability level. The data were analyzed using R Software (Version 4.3.2). The use of Stopping Go® does not interfere with the architecture, yield, and productivity components Mon, 18 Nov 2024 00:00:00 GMT https://repositorio.uema.br/jspui/handle/123456789/4629 2024-11-18T00:00:00Z https://repositorio.uema.br/jspui/handle/123456789/2350 Título: Abobrinha (cucurbita pepo l). Sob adubação potássica na ausência e presença de mulching plástico Autor(es): Santos, Luísa Quitéria Bento dos Abstact: O aumento do cultivo da abobrinha italiana (Cucurbita pepo L.) tem impulsionado o desenvolvimento de tecnologias para o manejo eficiente dessa cultura, visando garantir altas produtividades. Assim práticas como o uso de cobertura do solo e adubação são opções eficazes para melhorar a produção das culturas, entre elas a abobrinha. Nesse contexto, objetivou-se com o presente trabalho, avaliar o cultivo da abobrinha italiana submetida a presença e ausência de cobertura com mulching. O experimento foi conduzido em fatorial 2×5, referentes a presença e ausência de cobertura com mulching e cinco doses de potássio (0, 50, 100, 150 e 200 kg ha1) em blocos casualizados, com quatro repetições e duas plantas por parcela. As variáveis analisadas foram altura da planta, diâmetro do caule, teor de clorofila, número de folhas, número de flores masculinas e femininas e número de frutos. Pelos resultados obtidos doses de potássio em torno de 100 kg ha-1 foram as que promoveram melhor resultado nas variáveis estudadas. As plantas dos tratamentos com mulching plástico mostraram-se superior em todos os parâmetros avaliados. Descrição: Santos, Luísa Quitéria Bento dos. Abobrinha (cucurbita pepo l).
