Características agronômicas e produção de fitomassa de milho verde em monocultivo e consorciado com leguminosas

Abstract

The objective of this work was to evaluate agronomic characteristics and phytomass of corn in isolated and associated cultivation with leguminous plants. The corn cultivar DINA-170 was used. The experimental design was that of randomized blocks, with four repetitions. The treatments were the isolated cultivation of corn (Zea mays L.) and the associated cultivation corn with black velvet bean (Stizolobium aterrimum Piper & Tracy) and corn with jack beans (Canavalia ensiformes DC.). There were no significant differences between treatments for stand, corn-cob weight with straw, length, number, weight and percentage of commercial corn-cobs, corn-cob rate, yield of fresh and dry matter. The corn-cob diameter in the treatments with corn in isolated cultivation and in associated cultivation with black velvet beans was greater than in associated cultivation of corn with jack beans.
