“…The fact that nitrogen did not affect the mass of 100 grains was also verified by Kolling and Ozelame (2017), who, using doses of 0 kg ha -1 , 25 kg ha -1 , 50 kg ha -1 , and 75 kg ha -1 of nitrogen, found no effect on seed mass. Other authors also found no differences in the effect of the nitrogen dose on the mass of 100 grains, such as Moreira et al (2013); Guimarães et al (2017), and Sabundijian et al (2016).…”

“…Some authors, such as Guimarães et al (2017) and Sabundijian (2013), found no statistical differences in nitrogen doses for bean grain yield. Kolling and Ozelame (2017) found that for every 10 kg of nitrogen applied; there was an increase in crop productivity of 14 kg ha -1 . Amaral et al (2016), in an experiment conducted in the city of Jaboticabal, SP, evaluated five doses of nitrogen (0 kg ha -1 , 40 kg ha -1 , 80 kg ha -1 , 120 kg ha -1 , and 160 kg ha -1 ) and observed that the doses influenced bean grain yield, in which the application of 136 kg ha -1 provided 2565 kg ha -1 of productivity.…”

Irrigation makes it possible to increase productivity in bean crops, but if mishandled, it can increase production costs and promote the leaching of nutrients, especially nitrogen, a nutrient that is fundamental for the development of the crop. Given the above, the objective of this study was to evaluate the yield of common beans subjected to different doses of nitrogen and water depths in the region of Uberaba – MG, Brazil. The experiment was conducted at IFTM – Campus Uberaba, in randomized blocks, consisting of four levels of irrigation (deficits of 15 %, 30 %, and 45 % and a factor without water deficit) and four doses of nitrogen (50 kg ha-1, 100 kg ha-1, 150 kg ha-1, and 200 kg ha-1) applied in stage V4 of beans. The cultivar used was BRSMG Majestoso. There was no interaction between irrigation levels and nitrogen doses for the variables studied. Nitrogen doses influenced linearly only leaf nitrogen content. The water deficit of 9.72 % was favorable to achieve maximum grain yields and favors the number of pods per plant. The plant mass in R6, a mass of 100 grains, hydration, and thermal sum declined linearly with increased water deficit.

“…The authors also concluded that genetic variability makes it possible to select more efficient cultivars for cultivation under conditions of low sulfur availability. Kolling and Ozelame (2017), when studying different combinations of nitrogen and sulfur dozen in off-season black beans, found that the combined use of nitrogen and sulfur resulted in higher grain yield, a higher number of grains per pod and longer pod length, increasing the yield of these components, in addition to the higher yield of grains per area. Pereira et al (2021), when studying the application of different sulfur dozens in the BRS Guariba and BRS Tumucumaque cowpea varieties under optimal irrigation conditions, found that the vegetative characteristics of these varieties were not influenced by the treatments, and the nutrient content available in the soil (32 mg dm-3) was sufficient for normal plant development.…”

RESUMOO feijão-caupi é uma cultura que se destaca pelo alto valor proteico, baixo custo de produção e grande importância socioeconômica para os núcleos familiares das regiões Norte e Nordeste do Brasil. Apesar da sua capacidade de tolerância à seca, ainda sofre com a baixa disponibilidade hídrica em seu cultivo, sendo um dos fatores limitantes para expressão do potencial produtivo da cultura. Alguns estudos reportam estratégias de cultivo e/ou métodos capazes de intensificar a defesa em plantas, a fim de amenizar os efeitos deletérios do déficit hídrico. Nesse contexto, a suplementação com enxofre (S) surge como uma alternativa para auxiliar as plantas nesse processo. O presente estudo teve como objetivo investigar a incorporação do enxofre nos tecidos das plantas e no solo após adubação com diferentes doses de S como tentativa de induzir a tolerância ao déficit hídrico em plantas de feijão-caupi [Vigna unguiculata (L.) Walp.]. Os experimentos foram conduzidos em dois ambientes de cultivo, casa de vegetação e campo experimental, utilizando duas cultivares de feijão-caupi (Xique-xique e Novaera) submetidas a dois níveis hídricos [controle (75% da capacidade de campo -CC) e estresse hídrico (45% CC)] e três doses de S (S-40, S-80 e S-120 kg ha -1 ). O estresse foi aplicado quando as plantas atingiram o estágio V4 , com duração de 21 dias em casa de vegetação e 28 dias no campo, e as coletas foram realizadas no final do estádio vegetativo. Plantas crescidas em casa de vegetação mostraram maiores valores absolutos de S nas folhas, caules e parte aérea quando comparadas àquelas cultivadas no campo.

A adubação nitrogenada e a irrigação são manejos necessários determinantes para uma boa produtividade. É necessário evitar o uso indiscriminado de adubos e dos recursos hídricos, utilizando técnicas agronômicas que diminuem os impactos socioeconômicos e ambientais. O estudo sobre a viabilidade econômica do feijoeiro é importante para definir gastos futuros, minimizar utilização de recursos naturais e aumentar a produção. O objetivo deste estudo foi avaliar economicamente a produção de feijão (cultivar BRSMG Majestoso) sob diferentes lâminas de irrigação e doses de adubação nitrogenada. O experimento foi conduzido no Instituto Federal do Triângulo Mineiro – Campus Uberaba. Foram utilizados quatro níveis de déficits de água no solo (15, 30, 45% e um fator sem déficit hídrico) e quatro doses de nitrogênio (50, 100, 150 e 200 kg ha-1), com quatro repetições, em blocos casualizados. Foram realizadas análises da eficiência econômica da lâmina de água e do custo de produção de feijão em função da adubação nitrogenada. Após estudo dos déficits, tanto a lâmina ótima econômica (446,6 mm) quanto a lâmina física (448,9 mm) encontradas, foram semelhantes e proporcionaram produtividades similares. O maior rendimento bruto foi de R$ 7.653,99 quando aplicado 100 kg ha-1 de nitrogênio. Palavras-chave: água; déficit; adubação; Phaseolus vulgaris L.; economia. Economic viability of bean, under irrigation blades and nitrogen doses ABSTRACT: Nitrogen fertilization and irrigation are necessary management determinants for good productivity. It is necessary to avoid the indiscriminate use of fertilizers and water resources, using agronomic techniques that reduce socioeconomic and environmental impacts. The study on the economic viability of beans is important to define future spending, minimize the use of natural resources and increase production. The objective of this study was to economically evaluate the production of beans (cultivar BRSMG Majestoso) under different irrigation depths and nitrogen fertilization doses. The experiment was conducted at the Federal Institute of Triângulo Mineiro - Campus Uberaba. Four levels of soil water deficits (15, 30, 45% and one without water deficit) and four nitrogen doses (50, 100, 150 and 200 kg ha-1) were used, with four replications, in randomized blocks. Analyzes of the economic efficiency of the water depth and the cost of bean production were carried out as a function of nitrogen fertilization. After studying the deficits, both the economic optimum blade (446.6 mm) and the physical blade (448.9 mm) found were similar and provided similar productivity. The highest gross yield was R$ 7,653.99 when 100 kg ha-1 of nitrogen was applied. Keywords: water; deficit; fertilizing; Phaseolus vulgaris L.; economy.
