QUITOSANA E AMINOÁCIDOS NO TRATAMENTO DE SEMENTES DE SORGO E MILHO

Abstract

To enable such extensive crops, seeds with high germinative power are essential, as the guarantee of better performance of a particular crop depends fundamentally on the quality of the seeds, characterized by germination and vigor. The efficient management and the use of technologies aimed at optimizing resources and increasing productivity become particularly important for producers to participate in increasingly globalized and competitive markets. Thus, this study aimed to verify the effects of treating sorghum and corn seeds with chitosan and amino acids on the physiological performance of seedlings. The experiment was conducted at the Seed Analysis Laboratory, belonging to IF Goiano Campus Iporá. The treatments consisted of applying six doses of the bioestimulant (0; 1; 2; 3; 4 and 5 ml kg-1 of seeds) from the company Patense, in sorghum and corn seeds. To evaluate the effect of seed treatment, the following tests were performed: Germination percentage; Seedling length; Seedling dry mass. The experimental design used was completely randomized, with four replications and six doses of the bioestimulant. The experimental data were submitted to analysis of variance, and when the seed treatment factor was significant, the means related to the characteristics were submitted to polynomial regression, defining the best fit according to the combination of significance and highest coefficient of determination. The doses of 4 ml/kg of sorghum seeds and 3 ml/kg of corn seeds of the growth stimulant provide the best performance of the seedlings.
