Componentes de produção de amendoim, cultivar br-1, em diferentes configurações de plantio
The peanut (Arachis hypogaea L.) is a grain that has high levels of proteins and oils, since it is consumed only roasted grain, even in fancy jams, pastries and dishes from Brazil and other countries. To enable good results regarding productivity at a lower cost, the use of row spacing and plant density on the line must be adequate, because the plant population is one of the most important factors to affect directly the components production. Given the dearth of information related to the behavior of peanut cultivar BR-1, grown in different populations in the Northeast, it was proposed in the present work was to study the effects of different planting configuration in the development and productivity of groundnut. We used the statistical design of randomized blocks with four treatments of planting the following settings: T1 - 0,50 m x 0,10 m with one seed per hole; T2 - 0,50 m x 0,10 m with one seed per hole; T3 - 0,50 m x 0,20 m with two seeds per hole; T4 - 0,50 m x 0,20 m with two seeds per hole and six repetitions, totaling 24. The experimental unit was composed of three rows of 4m and is considered the center line as floor area. Data were subjected to analysis of variance and means were compared by F test at 1% probability. The number of immature pods per plant was the only variable significantly upheld arrangements of cultivation and decreased with increasing plant density per hectare Although no statistical differences occurred for productivity, higher absolute values were found in the spacing of 0,1 meters between plants with two seeds per hole, justify the recommendation of this configuration planting.
