Desempenho da gliricídia adubada e irrigada com água residuária doméstica tratada

Abstract

Gliricidia (Gliricidia sepium) is a forage legume used mainly in animal feed. The species, in addition to fixing nitrogen, helps to control erosion, recover degraded soils and serves as a green manure. In the study in question, the objective was to evaluate the performance of gliricidia in consortium with cactus pear in rainfed cultivation and irrigated with wastewater. The experimental design was in randomized blocks, with a 2x2 factorial scheme (two irrigation conditions and two fertilization conditions) with repeated analysis over time. The significance of treatment, time and interaction time x treatment for the analyzed variables was verified, but only time was significant for most variables. Analyzes were performed at 360, 510 and 600 days for plant height, productivity and crown width. According to the results, it can be seen that the highest productivity was recorded at 600 days, while for crown width the best results were observed at 510 and 600 days. The diameter of the plants was analyzed in 4 different conditions and it was verified that the treatment where it received fertilization and there was irrigation presented the best results.
