COINOCULAÇÃO DE BACTÉRIAS FIXADORAS DE NITROGÊNIO COM A APLICAÇÃO DE COBALTO E MOLIBDÊNIO NA CULTURA DO AMENDOIM

Abstract

Peanut (Arachis hypogaea L.) is an oilseed crop of great food and socioeconomic relevance in Brazil and the world. Being the second most cultivated oilseed in Brazil. The experiment was conducted in a greenhouse at the Fazenda Escola do IF Goiano, in order to evaluate the effects of coinoculating seeds with Bradyrhizobium japonicum and Azospirillum brasilense and the application of cobalt and molybdenum on nodulation in peanut crops. The design used is a randomized block, with four replications, and a factorial combination (2 × 4) with the application or not of mo and co associated with four inoculation treatments. With the objective of evaluating the effects of seed coinoculation and the application of Co and Mo on nodulation, growth and dry matter partitioning of peanut plants. The data obtained were subjected to analysis of variance and compared using the Tukey test, at 5% probability. The application of inoculants and micronutrients, molybdenum and cobalt, proved to be a good strategy to improve cultivar development.
