PRODUTIVIDADE E RENDIMENTO COMERCIAL DE BULBOS DE CEBOLA EM FUNÇÃO DA DENSIDADE DE CUL TIVO Productivity and commercial yield of onion bulbs in function of growth density

The adequate distribution of onions ( Allium cepa L.) within a crop becomes necessary due to their influence on the competition for water, light, and nutrients, which determines the size of the bulbs and the total yield. The goal of this work was to evaluate the yield and commercial pattern of onion bulbs as a function of the crop density employed. The onion seedlings were produced on polystyrene trays with 200 cells filled with commercial substrate Plantimax®. The experiment was carried out according to a randomized block design (RBD), with four replications and 2-m 2 plots. The cultivar Buccaneer was evaluated in densities of 50, 75, and 100 plants m -2
