Different sowing arrangements for the BRS 423 OL peanut cultivar in Campo Verde-MT conditions

Abstract

The objective was to evaluate different peanut sowing arrangements with the cultivar BRS 423 OL, under the conditions of Campo Verde-MT. The experiment was carried out in the agricultural year 2019/20 with manual seeding on 12/11/2019, in the experimental area of "‹"‹the Federal Institute of Education, Science and Technology of Mato Grosso – São Vicente Campus, Campo Verde Reference Center, located in the municipality of Campo Verde – MT. The experimental design was in randomized blocks, with five replications. The treatments were different sowing arrangements: T1 – Population of 222,222 plants.ha^-1 in the spacing of 0.90 m between single lines and 20 plants.m^-1, T2 – Population of 222,222 plants.ha^-1 in the spacing of 0.73 mx 0.17 m between double lines and 20 plants.m^-1 and T3 – Population of 214,285 plants.ha^-1 in the spacing of 0.70 m between single lines and 15 plants.m^-1. The plots consisted of two lines three meters long, with an interval between plots of two meters and a useful plot of 5.4 m². Mass of 100 grains and pod yield were evaluated, observing a significant difference in the two variables. The highest yields were obtained in the population arrangements 222,222 plants.ha^-1 in the spacing 0.73 mx 0.17 m between double lines and 20 plants.m^-1 and the population 214,285 plants.ha^-1 in the spacing 0.70 m between simple lines and 15 plants.m^-1, both with yields above 5,400 kg.ha^-1.
