Abstract

This research was proposed to evaluate the results under different spacing and densities   arrangements on growth, development and productivity of peanut plants, cultivate BR-1, in an agricultural area on the banks of the Piranhas River, located in the municipality of Pombal-PB. Therefore, the study was developed in the experimental field, of the Agri-Food Science and Technology Center, located in São João farm, distant 18 kilometers from the city Pombal. This experiment was carried out from february to may/2017 as a factorial experiment laid out in Complete Randomized Block Design (CRBD), with six repetitions. Include two factors, spaces (0.10x 0.50 m and 0.20x 0.50 m) and density (one seed per hole and two seeds per hole) totaling 24 plots. The experimental unit was composed of three lines of 4 m, the central line being considered a useful area. Regardless of the sowing season, plant density or spacing are factors that most influence agronomic characteristics and pod productivity and grains of peanuts grown in the Sertao Paraibano. The number of immature fruits per plant was the only variable that significantly differed from the cultivation arrangements in relation to the others, showing better behaviors in the highest density of plants per hectare and in the largest spacing. Regardless of the sowing season, plant density or spacing are factors that most influence agronomic characteristics and in the productivity of pods and grains of peanuts grown in the Sertao Paraibano.
