Production and productivity of corn inoculated with Azospirillum brasilense fertilized with chicken bed

Abstract

Appropriate forms of plant nutrition, combined with the use of microorganisms that promote plant growth, is important to achieve balance and sustainability in agriculture. In this work, the main effects on corn as a function of seed inoculation with A. brasilense associated with fertilization with chicken litter were studied. The work was carried out in the field, in two areas, with an experimental design in randomized blocks, in a 2x6 scheme. The first factor was inoculation with A. brasilense and control. The second factor was six doses of chicken litter, established by the fertilization recommendation, using 0, 50, 100, 150, 200, 250% of the recommended dose for each area. At 60 days after sowing, morphometric analyzes were performed, such as plant height and stem diameter, stem dry matter mass plus sheath and leaf. At stage R6, approximately 150 days after sowing, the mass of a thousand grains and yield were determined. Chicken litter positively influenced yield, height and basal stem diameter and shoot dry mass of corn. A. brasilense promoted the increase in leaf mass, positively influencing the mass of a thousand grains and maize yield.
