Effect of Low Cost Storage Structure on Shelf Life and Quality of Onion Genotypes

The effect of fully ventilated storage structure on shelf-life and quality of onion genotypes was studied at CCS, Haryana Agricultural University, Hisar. The experiment was conducted in a single factor with one level with three replications. The lowest physiological weight losses % was recorded (7.19%) at 30 days and (14.81%) at 120 days in Hisar onion-4 and there was no seen sprouting up to 60 days in all the genotypes after storage and then after start gradually sprouting in the bulbs in storage. lowest sprouting % was recorded from 90 days and 120 days (2.16% and 3.65%) in Hisar onion-4 respectively. Minimum rotting % was recorded in Hisar Onion-4 and Hisar Onion-7 and total minimum losses were recorded in Hisar Onion-4 and Hisar Onion-7 among the genotypes in storage. Minimum total losses was recorded in best check Hisar Onion-4 closely followed by genotype Hisar Onion-7 during storage.
