Abstract

The research experiments were conducted to study the storage performance of onion from the year 2016 to 2021over seasons (kharif, winter, summer). Different onion genotypes were grown to study the storage losses. Onions grown inwinter seasons and stored through summer months were stored better (49.3 % loss) than summer (57.3 % loss) and kharif(73.8 % loss) grown crop. The mean performance of genotypes for storage loss varied from 32.28 % to 80.84 %, least in 2016and highest in 2020 attributed basically for variation in weather conditions, selection pressure and their interaction. Thestorage loss fitted well to curvilinear model (Y= 500.851 + (-11.996) x1 + (-2.910) x2 + (0.653) x3 + 16.437
