Arranjamentos espaciais e densidades de plantio na produção de repolho

Abstract

The change in spacing between plants and between rows (population density) and spatial Cupboards, promote significant changes in plants. A better understanding of these factors might provide better crop management, improved productivity and better quality cabbage. On that basis, the aim of this work was to evaluate different spacing and spatial Cupboards in cabbage culture. The experimental design was randomized blocks with 18 treatments and 3 replications in a factorial 3 x 3 x 2. Each plot consisted of 28 plants, and the ten central plants useful portion, used for evaluation. We evaluated three row spacings (0.4 m, 0.6 m, 0.8 m), three spacing between plants (0.3 m, 0.5 m, 0.7 m) and two space Cupboards (triangular and rectangular) and the treatments composed of the 18 possible combinations between the lines spacing, spacing between spatial plans and Cupboards. The evaluations conducted measured the following characteristics: head height, head diameter, head shape index, compactness, fresh and estimated total productivity. Considering the current Brazilian preference and the pursuit of higher productivity by the producer, the spacing of 0.4 x 0.5 m (rows and between plants, respectively) is the most suitable for promoting heads with marketable characteristics while maintaining high productivity. As for the space arranjamento (triangular or square), there was no interference to the characteristics evaluated
