ROTAÇÃO DE CULTURA E CONSÓRCIOS MILHO-FORRAGEIRAS NA COMPACTAÇÃO DO SOLO COM NITROGÊNIO

Abstract

Abstract: The intercropping of maize with forage species has been widely used to obtain high grain yields from the crop and greater accumulation of straw on the soil surface, and also to reduce soil compaction, which is a problem in agricultural areas, resulting in loss of crop productivity and environmental degradation. The aim of this study was to evaluate the physical properties of the soil and the productivity of maize intercropped with forage crops in the second harvest of 2024. The soil physical properties evaluated were: soil density, gravimetric moisture, volumetric moisture, total porosity, macroporosity and microporosity. The treatments were maize and piatã (MP), maize and stylosanthes (MS), maize and U. ruziziensis (MR), maize (M), maize with U. ruziziensis and stylosanthes (MRS), maize with piatã and stylosanthes (MPS), with 4 replications for each. The results presented show that the maize, Uruchloa ruziziensis and Stylosanthes (MRS) consortium obtained the best results compared to the other consortia, in terms of plant performance, there was a significant increase in the yield variable. The maize intercropped with Piatã (MP) had a higher total soil porosity.
