Desempenho agrônomico do milho em sucessão ao tomateiro e pastagem em diferentes manejos de adubação

Abstract

The objective of this work was to evaluate the agronomic performance of corn in succession to tomato (Solanumlycopersicum) and pasture (Urochloadecumbens) cultivation submitted to different fertilization management in the municipality of Carmópolis de Minas, MG.For this, 3 different experiments were established in contiguous areas, in succession to the culture of tomato and pasture under different fertilization managements: 1) with nitrogen fertilization in coverage in the area in succession to the tomato and without planting fertilization; 2) without nitrogen fertilization covering the area in succession to the tomato and without planting fertilization; 3) without nitrogen fertilization in cover in the area in succession to the pasture and without fertilization of NPK planting; 4) with nitrogen fertilization in cover in the area in succession to the pasture and without NPK planting fertilization; 5) without nitrogen fertilization in cover in the area in succession to the pasture and with NPK planting fertilization; 6) with nitrogen fertilization covering the area in succession to the pasture and with NPK planting fertilization.Each experiment was conducted under a randomized block design with four replications. The residual fertilization of tomato provides a reduction in the fertilization of the BR206 corn plantation in succession. The practice of nitrogen cover fertilization is of fundamental importance, as it is through this that corn is able to achieve high productivity. The cultivation of corn without correction of soil fertility can cause significant losses in productivity, regardless of the crop in succession
