Green and sweet corn grown under different cover crops and phases of the no-tillage system

ABSTRACT Special corn is cultivated all year conventionally round; however, its productivity increases when grown under a no-tillage system (NTS). This study aimed to evaluate the agronomic performance of sweet and green residues different cover crops NTS implantation stages. Two experiments were carried out in randomized block design, with four replications, each three areas. The consisted evaluating corn, simultaneously, areas at stages development NTS: initial (1 year), transition (7 years), consolidation (19 years) six types crops: Signal grass (SG), Pearl millet (PM), Sunn hemp (SH), mixture SG + SH, PM, PM SH. dry matter (DM) production crops, husked unhusked ears, straw, grain yield evaluated. SH had highest mass among studied phases NTS. phase did not influence ears or without husk corn. cultivation showed better yields compared system.
