Abstract

Closer spacing (10 cm × 10 cm) and planting on 25th November was the best for onion production under Manipur conditions to get higher productivity up to 358 q/ha. Closer spacing had higher leaf length (47.95 cm), leaf area (83.63 cm2), leaf area index (4.21), bulb dry matter (13.30%) and yield (253.40 q/ha), while wider spacing had higher number of leaves (8.18), average single bulb weight at harvest (56.24 g), polar diameter (4.79 cm) and equatorial diameter (49.39 mm). Planting on 25th November recorded maximum No. of leaves (8.26), leaf length (50.50 cm), leaf area (87.93 cm2), yield (267.20 q/ha), polar diameter (4.92 cm), equatorial diameter (53.68 mm), average single bulb weight (68.48 g), bulb dry matter (13.68%) and Harvest Index (72.92), while planting on 10th January had higher Leaf Area Index (4.04).
