Physiological indices of seedlings of maize (Zea mays L.) under the action of biostimulants

The present study aimed to evaluate the effect of biostimulants seedling growth of maize (Zea mays L.) through some physiological parameters that make up the analysis of growth. The experiment was conducted in a greenhouse at the Federal University of Tocantins. The experimental design was a randomized block design with four replications. The treatments consisted of three biostimulants (Bioradicante TM , Ecormon TM and Vitalem Forte TM ) used separately and in different combinations evaluated in five seasons to collect data (9, 18, 27, 36 and 45 days after emergence). The parameters studied were: specific leaf area, net assimilation rate, relative growth rate and absolute growth rate. Among the results, it was concluded that the use of products biostimulants stimulate the development and growth of maize seedlings, both applied to seeds as the leaves.
