Desempenho agronômico de híbridos de milho boliviano consorciados com capim mombaça

Abstract

Maize (Zea mays L.) is a relevant commercial plant in the Americas. Its economic importance is defined by the various forms of use, from animal feed to high technology industries. The Integrated Crop-Livestock System (ICLS) system was proposed as an alternative for the recovery and/or renewal of degraded pastures, but it is important to demonstrate the economic viability of this practice. The objective of this work was to analyze the agronomic characteristics of Bolivian corn hybrids when intercropped with forages of the genus Panicum maximum. The experiment was conducted in the experimental area of the Federal University of Mato Grosso do Sul, Campus of Chapadão do Sul-MS in the 2018/2019 crop year and consisted of a randomized block design with 4 hybrids of Bolivian corn cultivated in a single and intercropped with grass Mombasa, distributed in 4 repetitions. The following variables were evaluated: height of insertion of the first ear, plant height, stem diameter, ear length, ear diameter, number of rows per ear, number of grains per row, mass of one hundred grains and grain yield, using the tukey and scott-knott test at 5% probability. Statistical analyzes showed that the characters stem diameter, ear length and the number of grains per row are not modified according to the treatments, with insertion height of the first ear, plant height, ear diameter, number of rows per ear, mass of one hundred grains and grain yield are influenced according to the treatments. In this perspective, the work provided agronomic gains in the desired direction for the characters.
