Abstract

This experiment was conducted for studying the effects of PLANT DENSITY and NITROGEN fertilizer levels on the YIELD of ONION (Allium cepa L.) Primavera variety in Jiroft during 1999-2000. The experiment was split plot design in basis of RCBD design with three replications. The main factor was five levels of pure NITROGEN application (0- 45- 90- 135- 180 kg ha-1 ) and density as the subplot in four levels (250- 500- 667- 1000 thousand plants/ ha). The results of the first year showed that the levele of both factors had significant effect at %1 level. The highest YIELD obtained of 135 kg ha-1 N application and 667000 plants ha-1. In this year the N5D3 treatment had the highest YIELD (57.57 T ha- 1). The results of the second year showed that the experimental factors had significant effect on the YIELD, too. In this year N application as much as 135 kg ha-1 and densities of 667 and 1000 thousand plant ha-1 had the highest YIELD. The results of combined analysis showed that the highest YIELD (73.45 T ha-1) obtained by using of 180 kg ha-1 pure NITROGEN and in density of 667 thousand plant/ha (plant density 15 × 10 cm). This result can be recommended for Jiroft region.
