Comparación de métodos de programación de riego para el cultivo de brócoli (Brassica oleracea Var. Itálica)

Abstract:

The management of water resources is a very important topic for both the production and profitability of crops. However, considering the growing scarcity of water resources, it is necessary to design and implement more efficient irrigation strategies in order to optimize the water usage efficiency. The aim of this work was the comparison of the water requirements through the programming of irrigation methods. The evaluated treatments were performed in broccoli crop (Brassica oleracea var. Itálica): humidity probe Em50G (T2) and irrigation programmed by ETc evaporimeter tank method "A" class (T1). The results suggest that the irrigation T2 shown the best results, with an average yield of 22, 42 t ha-1 in comparison with T1 15, 45 t ha-1. Similarly, T2 used 19 irrigations during the entire crop cycle, compared with the 48 irrigations applied in T1, with a cumulative water volume of 780 m3 ha-1 and 1047, 5 m3 ha-1, respectively. The overall results suggest that T2 shown a better performance in terms of water usage efficiency, in comparison with T1.
