Inoculants associated with fertilizers: agronomic increases in bean, soybean and lettuce crops

Abstract

The objective of the study was to prove the efficiency of inoculation associated with synthetic fertilizers in the agronomic potential of bean, soybean and lettuce. Experiments were carried out in a randomized block design to evaluate the efficiency of inoculation associated with synthetic fertilizers in bean, soybean and lettuce crops. The experimental design used was randomized blocks organized in a factorial scheme, with six replications. In beans, ten treatments were evaluated in four environments. In soybean cultivation, 13 treatments were evaluated in four environments. While in lettuce, six treatments were evaluated in five environments. In each crop, the agronomic and nutritional characteristics were evaluated. Inoculation associated with fertilizers enhances the agronomic and nutritional performance of beans, soybeans and lettuce. Rhodopseudomonas palustris combined with phosphorus and nitrogen fertilization improves bean grain yield. Bradyrhizobium japonicum, Azospirillum brasiliense and Pseudomonas fluorescensare crucial for soybean. Addition of the bacterium Rhodopseudomonas palustris maximized the lettuce biomass.
