evaluation of organic amendments on microbial soil respiration and agronomic variables in banana

The effect of the use of organic amendments on soil microbial respiration and agronomic variables in banana plants was studied, evaluating 22 treatments consisting of three amendments and four organic products, each in three doses and control treatmet (no amendment). The results showed significant increases in soil microbial respiration, with high doses of vinasse and mycorrhizae at 90 days after transplantation. In the agronomic variables were found significant differences of increase of height, diameter of pseudotallo and dry matter, with the amendments: vinaza, shrimp fluor, humus and biostimulant. Therefore, from the results obtained it can be concluded that the organic amendments increased the microbial respiration activity and stimulated the agronomic development of the banana plant.
