Abstract

Onion variety Agri Found Light Red was grown at increasing plant densities viz; S1: 15 x 10 cm; S2: 15 x 15 cm; S3: 20 x 15 cm and different transplanting dates P1: 15th November; P2: 25th November; P3: 5th December; P4: 15th December and P5: 25th December. The experiment was laid out in a Randomized Block Design with Factorial Concept (FRBD) with three replications and 15 treatment combinations, comprising of 5 levels of transplanting dates and three levels of spacing. Results revealed that different transplanting dates and spacing indicated significant effect on different characters viz; plant height, polar diameter, equatorial diameter and number of leaves per plant but failed to show significant effect on days to maturity, % bolters, % jointed bulb and T.S.S. Among the different transplanting dates early planting P1 (15th November) recorded the highest vegetative growth (80.9 cm), marketable yield (29.87 t/ha) and total yield (30.58 t/ha). Among the different spacing, S1 (15 x 10 cm) showed significant effect on marketable yield (32.67 t/ha), total yield (33.59 t/ha) and number of bulb (644786.1) harvested per hectare as compared to remaining treatments. Onion cv. Agri Found Light Red transplanted on 15th November and 15 x 10 cm spacing significantly improved the number of bulbs harvested per hectare (650085), marketable yield (34.65 t/ha) and total yield (35.30 t/ha).
