Efeito de espaçamento entre plantas sobre o rendimento e tamanho do bolbo de cebola - AHium cepa L. nos arredores de Maputo

Abstract

In order to determine the influence of plant spacing on onion yield, a trial was set up in the Experimental field of the Faculty of Agronomy. For this purpose, seven bars were evaluated using a randomized complete block design with 4 repetitions. The dry matter yield of leaves, bulbs and plant were measured at 20, 40, 60, 80 and 100 days after transplanting. At harvest, the bulbs were classified into three fractions (large, medium and small) and their yields determined. Analysis of variance was performed for all variables and means were separated by Duncan's test (5%). During the cycle there were significant increases in dry matter yield (from leaves and bulbs) with high densities. At harvest, the highest dry matter yields were also observed at the highest planting densities. The highest yield of the bulb was produced in spacings of 20 cm x 7 to 12.5 cm. Therefore, for the study area, the 20 cm x 12.5 cm compass is recommended(TRADUÇAO NOSSA)
