Sedimentos de tanque de piscicultura na produção de cenoura em sucessão com feijão-caupi

Abstract

The use of fish farming residues in cultivated fields is currently well seen in the sustainable environmental parameters of agricultural production. In this context, the aim of this study was to evaluate the use of solid waste from fishponds and their interactions with NPK and limestone in the production of carrots and cowpea in succession. The experiment was designed in randomized blocks, with four replications and fourteen treatments, being carried out in the field on a Dystrophic Yellow Latosol. The addition of solid residues from a fishpond increased the production of tuberous carrot root as a function of doses and combinations of residues and levels of mineral supplementation. The greatest effects of residues were in relation to yield, size and tuberous root diameter.
