APLICAÇÃO FOLIAR DE BIOMAPHOS EM MILHO SAFRINHA

Abstract

The work aims to evaluate agronomic responses of hybrid corn P 4285VYHR submitted to application of doses of BiomaPhos® via foliar. The experiment was conducted in the agricultural year 2021, from February to July, at Fazenda Córrego do Oriente in Nova Glória - GO under no-tillage. The experimental design used was a randomized block 5 x 1, five doses of BiomaPhos® (0; 0.25; 0.50; 0.75 and 1.0 L ha-1) and a corn hybrid (P 4285VYHR) with five repetitions. The variables analyzed were: Height of plants (AP) obtained following the methodology proposed by Silva, et al. (2015); height of the first ear (APE), in meters; methodology by Demetrius et al. (2008), ear diameter (DE), in millimeters; tenon length (EC), measured in millimeters with a digital caliper; grain row number (NFG); number of grains per row (NG/F); Thousand grain mass (M1000) in grams, obtained following the methodology proposed by RAS (2009); productivity (PROD). Data from all variables were subjected to analysis of variance and means were compared by Tukey's test with a significance level of 5%. There was no significant interaction between the doses and the hybrid, thus, the analyzes were performed individually. There was no significant difference in doses in any of the variables. The dose of 0.25 L ha-1 provides better profitability when used in foliar application, under the conditions in which the work was carried out.
