Utilização de biofertilizante e adubação química em capim-piatã (Brachiaria brizantha)

Abstract

Objetivou-se avaliar o desenvolvimento de capim-piatã (Brachiaria brizantha)recebendo níveis de adubação orgânica (0, 1,0, 2,0, 3,0 e 4,0 L de biofertilizante líquido de esterco bovino por vaso), em diferentes condições de adubação química (sem adubo químico - controle, com aplicação de 50 % e 100 % da recomendação de adubação química). Observou-se efeito (P<0,05) do biofertilizante associado ou não com adubação química em todas as características morfogênicas e estruturais do capim-piatã, exceto na duração de vida das folhas com 100% da adubação química. Observou-se ainda efeito (P<0,05) linear do biofertilizante na taxa de alongamento foliar e senescência foliar em todas as condições de adubação química. Já quando se adotou uma dose de 50% da recomendação, observou-se efeito (P<0,05) linear na taxa de aparecimento foliar, filocrono e número de folhas vivas. A substituição total ou parcial da adubação química pelo suprimento com biofertilizante pode ser promissor no desenvolvimento do capim-piatã.
