Item Simulação de produtividade em função de diferentes níveis de uniformidade para cultura do feijão carioca com irrigação localizada(2023-04-13) Batista, Arthus Douglas; Mélo, Ralini Ferreira de; http://lattes.cnpq.br/4296426234246190; http://lattes.cnpq.br/2013424295271323Water is one of the main factors for agricultural production and one of the most used parameters to evaluate the irrigation system is the uniformity of the application of the water layer over the irrigated area. This work was carried out with the objective of evaluating the productivity of the common bean (Phaseolus vulgaris L.) cv. Carioca due to different levels of uniformity simulated using Solver, which is a software for mathematical programming integrated into an electronic spreadsheet (Excel). The Keller & Karmeli (1975) model was used as a reference for simulations of the water depths of a system with drip irrigation and the productivity was estimated according to the methodology proposed by Figueredo et al. (2008). As a result, the highest mean depth value (568.1 mm) and lowest productivity (1991.3 kg ha-1) of the common bean crop were obtained for the system that presented a CUC of 65%. On the other hand, the lowest mean depth value (416.4 mm) and highest productivity (2981.1 kg ha-1) were obtained for a system with 95% CUC. In a direct comparison, a 26.7% reduction in the mean blade value and a 49.71% increase in productivity were noted, thus confirming that a system with greater uniformity is more efficient.
