Abstract

Peanut culture is well adapted to growing conditions in the state of Mato Grosso, but information to optimize cultural management, such as planting density, is scarce. The present work aimed to evaluate the agronomic performance of BRS 423 OL peanuts, cultivated in different sowing densities under the conditions of Campo Verde-MT. Sowing was done manually on November 22, 2019. The experimental design used was in randomized blocks, with four replications. The treatments were five seed densities m-1: 10, 15, 20, 25 and 30 seeds m-1, with the cultivar BRS 423 OL. The plots were composed by four lines of three meters in length, spacing between lines of ninety centimeters, interval between plots of two meters and a useful plot of 10.8 m2. The harvest was carried out on March 20, 2020, 112 days after the emergency. Dry mass per plant (g), number of pods per plant, final plant stand.m-1, mass of 100 grains (g) and pod yield (kg ha-1) were evaluated. Seed densities influenced dry mass per plant, number of pods per plant, final plant stand.m-1 and mass of 100 grains, so that the lowest densities (10 and 15 seeds.m-1) produced quantities of pods statistically compatible with the highest densities (20, 25 and 30 seeds m-1).
