Fonte de adubação orgânica para cultura do caupi Vigna unguiculata (L) Walp.

Abstract

This work aimed to evaluate the effects of organic fertilization on the culture of caupi varo IPEAN-69, in a greenhouse, using cattle and chicken manure, organic compost, mucuna preta and feijão-de-porco at doses of 0,1,2 and 3%, with 3 repetitions. The highest average dry matter production (l9.3 g/vine) occurred in the 3% dose of cattle manure, against 1.1 g/vine of the control. A decrease in production was observed as a function of the doses in the treatments with chicken manure and cowpea. Cattle manure, at a dose of 2%, produced the greatest amount of nodules, while in the treatments with chicken manure and cowpea there was no nodulation. The results obtained show that cattle manure, organic compost and black mucuna, at a dose of 2%, are promising for the culture of caupi, requiring the validation of these results in field conditions.
