COMPONENTES DE PRODUÇÃO DO AMENDOIM CULTIVAR BR- 1 SUBMETIDO A DIFERENTES ESPAÇAMENTOS ENTRE PLANTAS E TIPOS DE SEMEADURA

Abstract

One of the factors that interferes on cultivation yield is the plants population, which in turn, is determined by the planting spacing. So, the choice of better space between plants and the right seeds numbers for pits, can reduce the and production costs, mostly because of the reduction of the treatment cultivation and higher yield. The goal of this work is to evaluate the production components of BR-1 peanut cultivation submitted to different spacings between plants and types of sowing. the experiment was accomplished in the city of Areia-PB, in the period of October 2016 to February 2017. The statistical design of randomized blocks was used in a 2 x 4 factorial scheme, with three replications, totaling eight treatments. The treatments consisted of two spacings between plants (0.10 x 0.50 m and 0.20 x 0.50 m) and four types of sowing (one seed out of the pod per pit, two seeds out of the pod per pit, two seeds Inside the pod per pit and three seeds inside the pod per pit). The data were analyzed using the F test and the average were compared by the Tukey test at 5% probability. Characteristics evaluated: Number of pods per plants, weight of 100 pods, percentage of dried pods, percentage of perfect seeds, productivity. It was observed the non-significance in most of the production components, did not allow the differentiated recommendation of any of the spacings studied. The greater weight of 100 pods and percentage of perfect seeds, besides the lower percentage of pods, were determinant for the higher productivity obtained in the treatment in which the sowing with two seeds outside the pod was used.
