DOSES DE BACILLUS ARYABHATTAI NO CRESCIMENTO INICIAL DA CULTURA DO MILHO

Abstract

The objective of this research was to evaluate the effect of doses of B. aryabhattai through seed treatment on the initial development of maize cultivars. The experiment was conducted at the Federal Institute of Goiás - Cristalina Campus, in a greenhouse, on four maize cultivars (Zea mays L) that were treated via seed with the bacterium B. aryabhattai, between the years 2023/2024. The experimental design was randomized blocks, in a 2x5 factorial scheme, with four replications. The factors tested were 2 maize cultivars and 5 doses of B. aryabhattai in seed treatment (0, 2.0, 4.0, 6.0 and 8.0 ml/kg of seed). The variables analyzed were plant height, stem diameter, number of leaves per plant, shoot fresh mass, root fresh matter, shoot dry matter and root dry matter. The data obtained were submitted to analysis of variance by the F test and in the highest coefficient of determination (R2) for regression. In the first experiment, conducted in the summer harvest, the data did not differ statistically between the treatments, but in the second experiment, conducted in the off-season, the doses of B. aryabhattai promoted increases in the plant growth data up to the dose of 4.0 mL/kg of seed.
