Posição da semente de milho na semeadura e sua influência no desenvolvimento e produtividade

Abstract

Sowing seeds in the proper position provides a fast germination and quickly seedling emergence speed, which consequently become less vulnerable to adverse conditions imposed by the environment by the way that emerging faster from the soil the seedlings will spend less time in the early stages of development. The experiment was conducted at the experimental field on the Federal University of Fronteira Sul (UFFS) - Campus Erechim. The object of the study was to evaluate the influence of the soil seed position on the development and yield of maize, it was used the Pioneer P1630H hybrid, sown on October 29, 2015, in plots measuring 3.5 m by 3.5 m. It was used a randomized block design, with seven treatments and four replications. The data were submitted to analysis of variance by F test and means were compared by Dunnett test at 5% probability. Before harvest, two variables were analyzed: ear insertion and plant height. The variables analyzed after harvest was ear length, grain rows per ear, grain per ear, thousand grain weight and yield. The harvest took place on March 17, 2016. It was verified that there were no significant differences (p>0,05) between different seed position on the planting rows for the agronomic components of development and yield.
