COMPONENTES DE PRODUÇÃO DO CULTIVAR DE AMENDOIM CNPA BR-1 SUBMETIDO A TIPOS E DOSES DE INOCULANTES

Abstract

The peanut (Arachis hypogea L.) is one of the most cultivated legumes in the world, mainly for its multiple food and industrial uses. This culture requires large amounts of nitrogen for its vegetative and reproductive development, making necessary the satisfactory contribution of this nutrient as the large quantities of N exported by the grains and pods. The present study aimed to evaluate the production components of a peanut cultivar submitted to doses and types of liquid and turfous inoculation in the region of Brejo Paraibano. The experiment was carried out in an experimental area belonging to the Agricultural Sciences Center of the Federal University of Paraíba, located in the city of Areia. The peanut cultivar CNPA BR-1 was used. The experimental design consisted of a double factorial (2 types of inoculants x 3 dosages of application), conducted in randomized blocks, with six treatments and four replications, totaling 24 plots. The experimental units were composed of four 3m rows, spaced 0.50 meters between rows and 0.10m between plants. The useful area was formed by the two central lines of each plot, where data were collected on the evaluated characteristics: number of pods per plant, weight of 100 pods (g); percentage of pods (%); percentage of perfect seeds (%); weight of 1000 seeds (g) and productivity (kg.ha-1). The data were analyzed through analysis of variance, using the F test and the means of the treatments compared by applying the Tukey test at 5% probability. It was not observed by the F test, a significant effect for none of the characteristics analyzed, and no interaction was found. The doses and types of inoculants applied did not significantly influence the results of the production components evaluated in the BR-1 peanut cultivar.
