“…SANTANA et al (2008) found that the cultivar BRSMG Talismã when subjected to the water depths considered deficient as well as excessive, reduced most of its evaluated variables. LOPES et al (2011) evaluated the productivity of bean crop under different methods of irrigation management, verified that the highest yields were 3031.11 kg ha -1 and 3005.02 kg ha -1 with management performed by Class A pan and Hargreaves-Samani equation (to obtain the reference evapotranspiration). FARINELLE & LEMOS (2010) found an average yield of 4157 kg ha -1 and 4564 kg ha -1 of growing bean in the dry season in two years of production, when evaluating different genotypes in the city of Botucatu, SP.…”

“…Faced the technological advances and socioeconomic characteristics, the bean cultivation has been practiced by farmers who have the most varied levels of technology, in which are highlighted irrigation and nitrogen fertilizer (LOPES et al, 2011). The participation of irrigation in the production costs of beans ranged from 26.6 to 37.6% in experiment conducted by OLIVEIRA & ZOCOLER (2010).…”

The current study intended to determine the optimum water depth, yield and evapotranspiration (ETc) for bean cultivars. The experiment was conducted in the Campus of Unit I of the Triângulo Mineiro Federal Education and Technology Institute in Uberaba, MG, in a completely randomized design with three replications. The treatments consisted of four water-replacing levels in the soil (70, 100, 130 and 160% of the crop evapotranspiration) and four bean cultivars (Pérola, BRSMG Madrepérola, BRSMG Majestoso and IAC Alvorada). The average values of ETc obtained for soil water balance for the cultivars Pérola, BRSMG Madrepérola, BRSMG Majestoso and IAC Alvorada were, respectively, of 5.25 mm day-1, 4.59 mm day-1, 4.54 mm day-1 and 4.77 mm day-1. The water depths which provided the highest yields were for the cultivars Pérola, BRSMG Madrepérola, BRSMG Majestoso and IAC Alvorada of 451.61 mm, 454.41 mm, 504.71 mm and 344.30 mm, respectively. The maximum yields found were 4597.87 kg ha-1 (Pérola), 4546.27 kg ha-1 (BRSMG Madrepérola), 4253.39 kg ha-1 (BRSMG Majestoso) and 3958.50kg ha-1 (IAC Alvorada).

“…Conforme colocado por Doorenbos & Kassam (1994) e em razão do curto período do ciclo do feijoeiro, pequenos períodos de deficiência hídrica podem afetá-lo severamente. Os resultados obtidos se assemelham aos de Pavani et al (2008) e Lopes et al (2011); esses autores também observaram maiores produtividades no feijoeiro irrigado manejado com base na evapotranspiração estimada pelo método do tanque Classe A em comparação com manejo por tensiometria; apesar disto, resultados diferentes foram obtidos por Lopes et al (2004), que compararam o desempenho dos métodos da tensiometria, balanço hídrico e tanque e obtiveram economia de 15% na água de irrigação aplicada com manejo por tensiometria, sem afetar a produtividade de grãos do feijoeiro. Tabela 2.…”

RESUMOEste trabalho foi desenvolvido com objetivo de se avaliar três formas de manejar a irrigação do feijoeiro. A cultivar de feijão preto BRS Supremo foi submetida ao manejo da irrigação por tensiometria, tanque Classe A e Penman-Monteith. Avaliaram-se a produtividade de grãos, número de vagens por planta, número de grãos por vagem, massa de 100 grãos, altura da planta, lâmina total e eficiência de uso da água. O método do tanque propiciou a maior lâmina acumulada e a maior frequência de irrigação. A lâmina total estimada por tensiometria foi 29,7 e 17,8% menor que a estimada pelos métodos do tanque e de Penman-Monteith, respectivamente. Houve diferenças significativas quanto à produtividade de grãos, número de grãos por vagem e altura da planta. O método do tanque propiciou a obtenção de maiores produtividades enquanto o método da tensiometria levou à economia de água de irrigação ocorrendo, no entanto, redução da produtividade. Plantas de feijoeiro submetidas a déficit hídrico de 21 e 37%, respectivamente, nas fases vegetativa e reprodutiva tiveram sua produtividade reduzida em 29%. Déficit hídrico de 22% na fase reprodutiva reduziu a produtividade do feijoeiro em 15%. Não foram observadas diferenças significativas na eficiência do uso da água. Palavras-chave:Phaseolus vulgaris L., necessidades hídricas, tanque Classe A, Penman-Monteith Irrigation management in bean crop cultivated in no-tillage system ABSTRACT The objective of this research was to evaluate three methods of irrigation management in the bean crop. The variety of black bean BRS Supremo was submitted to irrigation management by tensiometry, Class A pan method, and Penman-Monteith. The productivity of grains, number of grains per plant, grains per berry, weight of 100 grains, height of plants, total water depth and water use efficiency were evaluated. The method of the Class A pan promoted the largest accumulated water depth and the largest irrigation frequency. The tensiometry underestimated in 29.7 and 17.8% the total water depth estimated by the Class A pan method, and Penman-Monteith, respectively. The results demonstrated that there were significant differences for the productivity of grains, number of grains per berry and height of plants. The Class A pan method favored larger productivities, while the tensiometry took the economy of irrigation water, having, however, reduction of the productivity. Bean plants subjected to water deficit of 21 and 37%, respectively, in the vegetative and reproductive stages, have their productivity reduced by 29%. Water deficit of 22% in the reproductive stage reduces the productivity by 15%. There were no significant differences in the water use efficiency.

Agricultural Water Management

a b s t r a c tBrazil is one of the top world producers of the staple commodity common bean (Phaseolus vulgaris L.). Irregular distribution of rainfall and the lack of rain during the crop reproductive phases affect its yield and increase the demand of water for irrigation. However, in recent years, water resources have decreased and water saving has become an issue. Thus, soil management techniques, which reduce evaporation, and efficient irrigation programming, through the monitoring of soil water content, could be adopted in water scarcity scenarios. This study assesses the effect of crop residues management (incorporated IR or left on soil surface NR) in soil water availability (and its retention in the soil pore space), and yield in common beans cultivated under no-till and directly seeded in an irrigated farm located southwest of São Paulo state. Soil water content was monitored with TDR probes installed within the 0-20 cm layer and its retention was assessed through the soil water retention curve. For the same irrigation management, the IR led to soil water content was lower than NR but both soil managements had similar available water and their demand of water for irrigation was similar. For the same soil water content, NR soils could hold it tightly in the pore space and the root plant system would require higher energy to absorb it. Then, it is foreseen that the root system in IR soils will be shallower than in NR soils, since it will withdraw water easily within the first 20 cm, however, in NR, the roots will extend deeper searching for available water. Considering 40 kPa as a threshold value, the plants suffered water stress during all crop cycle at the same physiologic stages in both soils. The variables studied to assess yield presented no-statistical significance in the T test at significance level of 0.05.
