Abstract
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).
Highlights
Beans are one of the food produced in greater quantities in the whole national territory, being intense the search for productive and adapted cultivars to cultivation regions (FARINELLI & LEMOS, 2010)
Considering the above, the aim of this study is to determine the optimum water depth, the productivity and the evapotranspiration of beans cultivars grown in Uberaba, MG
ARF et al (2004) realized maximum irrigation of 219 mm and do not reach statistical difference in productivity when irrigated with different water depths
Summary
Beans are one of the food produced in greater quantities in the whole national territory, being intense the search for productive and adapted cultivars to cultivation regions (FARINELLI & LEMOS, 2010).From the 1980s the beans began to be cultivated in the winter. Beans are one of the food produced in greater quantities in the whole national territory, being intense the search for productive and adapted cultivars to cultivation regions (FARINELLI & LEMOS, 2010). According to the same authors, at this time the beans have the greatest acceptance among medium and large producers, by obtaining higher yields compared to other times of the year (BINOTTI et al, 2007). 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). FREITAS et al (2003) said that water is one of the production factors in agriculture, and every species needs an adequate level of water in the soil for their physiological needs to be satisfied
