Effects of biostimulants application in cotton seeds.
Journal Title: Revista Verde de Agroecologia e Desenvolvimento Sustentável - Year 2017, Vol 12, Issue 1
Abstract
The culture of cotton comes settling in Brazil as the more tecnificated, generating each year new technologies that help this growth, being the use of biostimulants one of them. Aiming to expand studies in the area, the present work aimed to test bioregulators doses without cotton seed treatment and evaluate your influence on germination and seedling vigor. The experiment was conducted at the Seed Analysis Laboratory of the Federal University of Uberlândia, in a randomized complete block design with four replications. Were evaluated five treatments for compounds different doses of two bioregulators, being 2; 4 and 6 ml kg-1 seed to bioregulators registered as a leaf fertilizer, 6 ml kg-1 seeds to bioregulators growth regulator and 6 ml kg-1 seeds with distilled water. Was evaluated the germination percentage, root green mass, aerial and total part, root dry mass, aerial part and total and root length, aerial part and total. The product registered as a leaf fertilizer at the dose of 6 mL kg of seeds-1, presents a higher percentage of normal seedlings, in relation to the subject. The largest total and root length is observed at the dose of 2.4 mL kg of seed-1 of biostimulant registered as a leaf fertilizer. The application of biostimulants at the doses used does not affect the variables of dry and fresh mass of aerial part, root and total.
