Abstract
INTRODUCTION: The snap bean (Phaseolus vulgaris L.) is a vegetable consumed around the world. The physiological and morphological quality of pods are important characteristics for determinate the commercial pattern, so techniques must to be used for increase the production of pods. Inoculation and application of nutrients on the leaves are management practices with great response and low cost.
The aim of this work was to evaluate the seed inoculation with Rhizobium tropici strains and the leaf application of molybdenum and cobalt on the yield of snap bean genotypes with determinate growth pattern.
MATERIAL AND METHODS: The experiment was conduct in a greenhouse and was used the genotype UEL 2. The experimental design was complete randomized with four replications, resulting in a 2 vs. 4 factorial (2- with or without inoculation; 4- doses of commercial product) . The seeds were inoculated with a mix of Rhizobium tropici strains (SEMIA 4077, SEMIA 4080 and SEMIA 4088) following the method of Furlan et al. (2016) and the doses used were 0, 50, 100 and 150% of the ML71 recommended dose (mix of molybdenum and cobalt). Were evaluated number of pods per plant, fresh mass of pods and potential yield of snap bean culture. The data was submitted to analysis of variance and the averages were compared by the Tukey test (p<0.05) and adjusted by polynomial regression equations.
