Strategy in the selection of corn genotypes for their efficiency and response to nitrogen

Abstract

Corn is of great importance in the national economy, being one of the most produced and exported cereals in Brazil. With the growing concern of producing food for the population, the search for new corn genotypes is increasingly intensified in order to obtain efficient seeds with an adequate response to the particularities of each planting region. In this sense, the present work aims to identify genotypes of corn efficient and responsive to the use of nitrogen for grain production in the Cerrado biome. The studies were carried out in two maize trials at the

Path Analysis for Maize (Zea mays) Silage Cerrado-Amazon Ecotone

“…Nitrogen plays a fundamental role, being the element required in greater quantity because it constitutes many plant components in the plant, consequently contributes to the greatest effect on productivity, being evident in the analysis of variance (Table 2), where the coefficient of variation found for all variables studied is considered low. Due to the influence of nitrogen fertilization, the coefficient of variation found is considerably lower in High N, besides demonstrating more concise mean values among the eleven maize genotypes [26,29].…”
