Additional application of bio-stimulants in a common bean (Phaseolus vulgaris l.) reproductive stadium with an increasing intuit in productivity

Abstract

The present work had as objective to evaluate the productive response of the bean due to the additional spraying of biostimulants. a randomized complete block design with 6 treatments and 5 replications. Three products were used to compose the treatments: 1 - 4-Indol-3-ylbutyric Acid (0.05 g/L), Kinetin (0.09 g/L) and Giberelic Acid (0.05 g/L); 2 - Giberelic acid (400 g/kg); 3 - Gibberellic acid (18.8 g/L) and Benzyladenine (18.8 g/L). The evaluated variables consisted of plant height, stem diameter, number of nodes per plant, number of pods per plant, number of grains per pod, mass of one thousand grains and productivity. The Scott-Knott 5% probability was performed. There was no statistically significant difference for the variables, except for productivity, in which the best treatments were 4, 5 and 6. Therefore, among these treatments the best one due to the cost-benefit was the T4.
