N-53 was grown as a rabi crop on a sandy loam soil. Three rates of Zn (0, 10 or 20 kg/ha, as Zn-EDTA) and S (0, 30 or 60 kg/ha, as elemental sulfur) were applied. Onions (without roots, or without leaves and roots) were cured for 10 days, then either hung in 5-kg bunches, kept on a cardboard tray in 5-kg piles on a wooden platform, or wrapped individually in paper and packed (5 kg) in 30% perforated paper packets on a wooden platform, under ambient conditions. Application of Zn alone or with a low rate of S (30 kg/ha) resulted in low rates of rotting, sprouting and physiological weight loss. All these storage parameters gradually increased with an increase in storage durationirrespective of storage method, but they were significantly lower for onions kept in 30% perforated brown paper packets; hanging in bunches was next best. The application of Zn alone at 10 kg/ha resulted in the highest yield (18.40 t/ha) with a low percentage of rotting (11.1%), sprouting (1.8%) and physiological weight loss (3.1%), during 60 days' storage using the perforated paper packet method. 收起
