EVALUATION OF ARBUSCULAR MYCORRHIZAL FUNGI IN THE PRODUCTIVE PHASE OF SOYBEAN ASSOCIATED WITH DIFFERENT DOSES OF PHOSPHORUS

Abstract

The present work focused on the action of arbuscular mycorrhizal fungi, which perform symbiosis with plant roots, helping them to absorb more nutrients. In this sense, this study consisted of an experimental verification, in which it was sought to evaluate the action of these fungi in the productive phase of soybean, associating them with different doses of phosphorus, in order to find out if this would be a viable alternative for the replacement of the base fertilizer. This substitution, it was believed, could improve productivity and reduce the costs of producing this oilseed. Regarding the methodology, it was an experimental field study, in which Rootella BR, which contains mycorrhizal fungus, was inoculated and associated with phosphorus in different dosages; considering that the study was divided into eight treatments, with and without fungi, and with different doses of P2O5. This material was analyzed using the qualitative-quantitative approach and the inductive method. It was noted as a result that, in fact, the association of arbuscular mycorrhizal fungi with phosphorus allowed a better development of the plant, especially its nutrition, which allowed an increase in this productivity. Still with regard to the results, it was noticed that the most successful treatments were those that contained more phosphorus.
