Adubação de biofertilizantes orgânicos de suínos na produção de mudas de açaí (Euterpe oleracea Mart.)

Abstract

In Brazil, swine farming has had a rapid increase in recent years. In this way, it led to the appearance of environmental problems due to the accumulation of swine manure. Currently, swine manure is one of the main existing polluting sources of soil, water and air, but pig manure has a potential for its reuse, whether in use as sources of nutrients for plants, energy generation, among others. This work aimed to evaluate the agronomic potential of swine manure to produce açaí seedlings. For this study, an experiment was carried out in a greenhouse to analyze the potential of swine manure on açaí seedlings under different irrigation shifts. The experimental design used was randomized blocks, with two factors and five replications. The species used for the experimental work was açaí (Euterpe oleracea Mart.), cultivar BRS pai d’égua. The results obtained in this work showed that swine manure showed a desirable agronomic potential and was equal to and superior to the additional factors. The biometric parameters stem diameter, root length, root dry mass. and shoot dry mass, were influenced by the interaction of pig manure factors and the irrigation shift. The irrigation shifts that obtained the best results for these biometric parameters were TR4 and TR5, which provide the maximization of water use and in relation to swine manure, the dosage that obtained similar effects and even superior to the levels that used fertilizers, was the dosage of DS400.
