Crescimento inicial de milho utilizando micronutrientes no tratamento de sementes

Abstract

There are a large number of products available in the market that aim to accelerate the germination and growth of corn plants (Zea mays). Therefore, an experiment was carried out in pots with the objective of evaluating the possible effects on the initial corn growth using micronutrients in the seed treatment, and a germination test, containing the same treatments. The experimental design was completely randomized (DIC), containing 5 plots and 5 replicates. The doses were equivalent to 0, 1.5, 3, 4.5 and 6 mL / kg of seeds. The pot experiment was evaluated weekly by measuring plant height. The physiological potential of the seeds was evaluated by germination test, first germination count, shoot length and root of seedlings and dry mass of shoots and seedlings. The results were submitted to analysis of variance adjusted to regression equations. According to the analysis, it was evidenced that the parameters evaluated did not present significant difference for the treatments in all the trials. It is believed that the availability of micronutrients in the soil and the seed reserve was sufficient to meet the initial demand of the plants conducted in pots. Similarly, it is believed that the seed reserves were enough to meet the demand for micronutrients. In addition, the duration of the laboratory tests may have been too short to obtain conclusive results.
