Abstract

Aiming at verifying the effect of GA3 and GA4+7, at the concentrations of 50, 100, 500 and 1000 ppm and GA4+7 + N(phenilmethyl)1H-purine-6-amine 50 and 100 ppm on bean plant productivity Phaseoius vulgaris L. CV 'Carioca'), in field conditions, an experiment on Fazenda Lageado, FCA, Campus de Botucatu, UNBSP, was settled. The treatments aplication was performed through foliar pulverization when the plant showed the 3rd leaf. It was determined the stem medium lenght, average number and weight of the beans formed by plant, average of the seeds weight by plant and productivity in Kg/ha, It was concluded that GA3 - 500 and 100 ppm respectively were the most efficient in increasing - the medium number and weight of the pods by plant. GA4+7 at concentrations of 500 and 1000 ppm seemed likely to increase the productivity of the bean plant growth in field conditions.
