Adubação foliar e uso de bioestimulante na cultura do feijão rajado no médio norte do Mato Grosso

Abstract

The Beans are one of the Brazilian feeding bases and one of the main sources of protein. This study aimed to verify the efficiency of application of nutrients to the leaves and the use of bio-stimulant in Brindle beans in the middle north of Mato Grosso. The experiment was conducted in the municipality of Vera - MT by direct seeding system under center pivot system in the 2013/2014 crop from May to August. The fertilizers used contained nitrogen, phosphorus, calcium, magnesium, sulfur, boron, cobalt, molybdenum, manganese, zinc, and copper, combined or not with biostimulant containing indole butyric acid (auxin), kinetin (cytokinin) and gibberellic acid (gibberellin). The experimental design was a randomized block, with 7 treatments and 4 repetitions which constituted 28 experimental units of 6 x 3 meters. Inside these was seeded to cultivate BRSMG Realce with spacings of 0.50 meters between lines, with 12 to 13 seeds per meter. The following characteristics were evaluated: plant height, first pod insertion, the weight of 100 grains, pods per plant, seeds per pod, sieve analysis and productivity. There was no significant difference in any of the variables even with the increase of more than 16% between the best treatment compared to control.
