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.

“…Irrigation frequency and planting density significantly influence the biometric and physiological traits of plants [26] and the grain's quality [25]. Usually, water deficit greatly affects the biometric traits of beans [12]. With mechanized harvesting, the traits related to the architecture of the plants are essential to reduce losses.…”

“…The state of Minas Gerais is the second-largest producer in the country, with 554.039 tons produced per hectare [8]. The potential yield of beans can be impaired in conditions of water stress due to the lag in the processes of transpiration and absorption as a result of the low water availability [9][10][11][12].…”

The correct irrigation frequency relies on the plant population density to increase yield and efficiency in water use. A field experiment was carried out in 2019 to study the effect of three irrigation frequencies, one (F1), four (F2), and eight (F3) days, and four planting densities, 20 (D1), 24 (D2), 28 (D3), and 30 (D4) plants per m2, on the variables: soil moisture, actual water consumption, growth, grain yield, and water productivity of beans (Phaseolus vulgaris L.). The soil water balance was calculated based on the soil moisture, which was measured by tensiometers. The irrigation was done by a drip tape. The variation in soil moisture was greatly influenced by irrigation frequencies and planting densities in F3. Plant growth was not affected by treatments. Irrigation frequencies and planting densities have deeply affected the biometric and chlorophyll synthesis traits of beans. The highest yields were found in the treatments F1D3 (2968 kg ha−1), F1D4 (2997 kg ha−1), and F3D3 (2946 kg ha−1). For water productivity, treatments with F1 irrigation frequency and the higher planting densities were more efficient in water use. Overall, the results are useful for technicians and farmers who work with irrigation management on beans.

“…Além da questão nutricional que é fornecida pelos substratos, e de acordo com Morais (2012), uma das etapas mais importantes na produção de mudas de qualidade é a irrigação, um fator que influência no crescimento e desenvolvimento da muda. A quantidade de água necessária para o cultivo de uma determinada espécie é um dado necessário e fundamental para se planejar e praticar um manejo adequado (Silva et al, 2017). Com a falta de água, a muda pode desenvolver deficiência de absorção de nutrientes e estresse hídrico; já o excesso, pode ocasionar lixiviação dos nutrientes e proporcionar microclimas, favorecendo o aparecimento de doenças.…”

O lodo de esgoto é um resíduo rico em matéria orgânica e nutrientes que pode ser incinerado ou depositado em aterros sanitários. Quando compostado, o lodo pode ser utilizado como substrato para a produção de mudas em viveiros. O objetivo desse trabalho foi avaliar o comportamento do mulungu (Erythrina speciosa), em relação ao uso de lodo de esgoto compostado (LEC), substrato comercial (SC) e diferentes lâminas de irrigação (L1, L2 e L3). Avaliou-se a altura, diâmetro do coleto e número de folhas bem como a produção de matéria seca. Para os parâmetros morfométricos analisados, altura e diâmetro do coleto, os maiores valores foram de plântulas que receberam 100% e 75% de LEC com L1. Para a produção de mudas de E. speciosa, é indicada a utilização da combinação de 75% de LEC e 25% de SC, podendo assim reduzir os custos de viveiro e o aproveitamento de um resíduo.
