Avaliação de diferentes concentrações de adubo orgânico produzido a partir de resíduos de pescados e vegetais no desenvolvimento da cultura do feijão caupi (vigna unguiculata (l) walp.)

Abstract

The recycling of organic waste, whose improper disposal may cause negative impacts on the environment, as in the case of fish waste from the fishing industry and vegetables are presented as an important tool to minimize the deficit of organic fertilizers for ecological production systems. Thus, this study analyzes the different concentrations of organic fertilizer produced from fish waste and vegetables in the development of cowpea crop (Vigna unguiculata (L.) Walp.) The following variables were evaluated: pod length (cm), number of pods per plant, number of grain per pod, weight of hundred grains (g) and yield per plant (kg / ha). For this research were tested seven treatments (0g, 400g, 800g, 1200g, 1600g, 2000g, 2400g) with three repetitions, totaling 21 treatments. The results revealed great potential of this compound for use in cowpea, treatments that performed best in culture were the T2 treatments (400g) and T7 (2400g) in terms of yield per plant, but statistically treatments do not differ at 5% significance level.
