ABSTRACT

Seeds of onion cv. Taherpuri were sown in the main field and simultaneously in the seedbed (to be transplanted later on) on 31 Oct., 15 and 30 Nov. and 15 Dec., 1992. Time of planting significantly influenced plant height, number and fresh weight of leaves/plant, size and weight of individual bulbs, dry matter content of bulbs and the yield. The diameter, weight and dry matter content (%) of bulb and yield declined with delayed planting. Onion planted on 31 Oct. produced the highest bulb yield (19.9 t/ha) while that planted on 15 Dec. had lowest yield (7.4 t/ha); however , the yield was significantly affected by other planting dates. In general, direct sowing resulted in higher yield (15.4t/ha) than the transplanted ones (12.2t/ha). Considering the interaction effect of time and method of planting, 31 Oct. directly seeded onion on 31 Oct. gave maximum yield of bulb (20.4 t/ha).
