Azospirillum, nicotinamida e Pseudomonas como bioestimulantes em milho

Abstract

The use of biostimulantes is an alternative for increasing the graind yield 23 of the corn crop. Thus, the objective of this work was to evaluate the action of 24 Azospirillum brasilense, Pseudomonas fluorescens and nicotinamide, applied via foliar 25 in the corn crop. The experimental design used was randomized blocks, with eight

10

26 treatments and four replications. The treatments consisted of a control treatment and the 27 application of A. brasilense, nicotinamide, Pseudomonas spp. and their combinations. 28 Growth characteristics, yield components and grain yield of corn were evaluated. The 29 joint use of Pseudomonas spp. + A. brasilense favored the corn crop, promoting 30 increases in plant height, height of insertion of the first ear, number of rows per ear and 31 productivity. The isolated use of A. brasilense provided an increase in stem diameter, 32 number of grains per row, grain mass per ear, thousand grain mass and ear length. The 33 isolated use of nicotinamide provided gains in the height of insertion of the first ear, 34 grain mass per ear and ear length, and the Pseudomas spp. provided only in ear length.
