Desempenho agronômico do milho em função da cultura sucessora

Abstract

The present work evaluated different rotated crop systems, applied to the agronomic performance of the corn, through the experiment carried out at the Experimental Farm of the Faculty of Agrarian Sciences of the Federal University of Grande Dourados (UFGD), in the city of Dourados-MS. The objective of this work was to evaluate the grain yield of the corn crop, cultivated as a function of the predecessor crop. The experimental design was a randomized block design (DBC), with five treatments and four replications. The treatments were composed of the following predecessor crops: millet (Pennisetum glaucum), canola (Brassica napus L. var. Oleifera), white oats (Avena sativa), forage turnip (Raphanus stivus L. var. Oleiferus), crotalaria juncea (Crotalaria juncea L.). The parameters evaluated were: plant height, stalk diameter, number of grains per spike, ear length and ear diameter, weight of one thousand grains and grain yield. The highest productivity was obtained when the maize was harvested in succession to crotalaria juncea, forage turnip and millet.
