DESEMPENHO AGRONÔMICO DO MILHO COM USO DE INSETICIDAS E BIORREGULADORES NO TRATAMENTO DE SEMENTES

Abstract

The grammar belonging to the Poacea family of the genus Zea species Zea mays is considered to be the world 's largest cereal with the objective of evaluating the efficacy of bioregulator seed treatment in two years. two sowing times. The experiment was conducted in two periods in the experimental areas of the Goiano Federal Institute Campus Ceres - GO. The first experiment is in the month of May 2017, under irrigation, by central pivot system. The second occurred in the months of November to May 2018 in the rainy season. An early-cultivar 2M99 VIP 3 was used. A 5x2x2 factorial scheme was used, with five doses of bioregulator (0, 0.5, 1.0, 1.5 and 2.0 L, 100-1 kg of seed), two insecticides (Thiamethoxam 350 g L-1 and Imidacloprid 150 g L-1 + Thiodicarb 450 g L-1), and two sowing times (irrigated and dry) with four replicates. Quality parameters: Plant height, First ear height, stem diameter, ear diameter, ear length, number of rows of grain per ear, number of grains on the vine, yield and mass of thousands of grains. The data were submitted to analysis of variance according to the doses of bioregulator and test for insecticides with the aid of software R. The treatment of seeds with different types of insecticides and dosages of bioregulator was not able to differentiate, but the production system O result is better than the number of species produced by the algorithm of number of sheets per second and number of parts in the list, length of spike, productivity and diameter of thatch. And a 0.5 dose of the biorregamento was generated by a productivity of 12011.75 kg ha -1.
