Field experiments were undertaken in Padra, Rewa to study the storage losses of onion due to sprouting, rotting, rooting and moisture losses in the storage. The treatments consisted 3 levels of N(50,100 and 150 kg N/ha) in the main plot, 5 levels of MH (0,2000, 2,500, 3000 and 3500 ppm) in subplot and 3 timings of spray (7, 14 and 21 days before harvest) in sub-sub plots with four replications during 1980-81 and 1981-82. After harvesting, onion bulbs were kept in bamboo baskets for five months i.e. from June to October, in ordinary room conditions during both years. The studies indicated that the application of 100 kg N/ha along with foliar spray of Maleic hydrazide at 3000 to 3500 ppm concentration at 21 days before harvest proved beneficial for onion production and reducing storage losses of onion bulbs in ordinary storage conditions.
