Abstract

Common bean hasan economic and social relevancefor the Brazilian population. Among the technologies that contribute to high crop yieldare growth promoters. This study objected to determine the growth promoters’effect, applied via seed or via seed and leaf, on the performance of super early common bean, cultivar FC-104, regarding the physiological(gas exchange and nutrient content) and agronomic (yield and itscomponents) indicators. The experimental design was a randomized complete block, with 13 treatments and fourreplicates. The treatments were constituted by the growth promoters (I) MicronutrientsComplex, (II) Leonardite; (III) Micronutrients+ fulvic acids, (IV) Micronutrients+ amino acids; (V) Micronutrients+ Ascophyllum; (VI) Micronutrients+ Eklonya; (VII) N + Zn; (VIII) N + K + amino acids; (IX) Growth regulators; (X) Trichodermaasperellum, (XI) T. asperellum+ Bacillus methylotrophicusand(XII) Peat. Seeds treated with water was considered control treatment(XIII). In treatments IV and XI, the plants had significantly higher stomatal conductance(gs)and number of pods per plant (NVP).In treatment V, theplants presentedhighervalue of leaf phosphorus (P), in both casesin relation to the control.However, there was no significant increase in grain yield of common bean treated with growth promoter
