Abstract

Five late kharif onion varieties were sown at three different dates for storability assessment under natural ventilation conditions at Department of Horticulture, Assam Agricultural University, Jorhat, Assam. The bulbs of various onion varieties had different shape and colours. Sprouting, rotting and rooting of bulbs were recorded from ten stored bulbs at 1, 2 and 3 months of storage and expressed in percentage. Weight loss at the end of three months in all the combinations were recorded during Kharif season for two consecutive years 2020-21 and 2021-22. Rots, sprouts and roots were generally low in the late kharif onion varieties in Assam conditions. Variety Bhima Super sown on 25th August (9.77%) showed good storage performance and variety Arka Kalyan (13.96 %) sown on 15th September exhibited poor storage performance

Conclusion

Based on research results, it can be concluded that the sowing dates, varieties and their interaction showed significant effect on most of the storage parameters of onion bulb. The variety Bhima Super (V4) emerged significantly superior with fewer losses in storage due to rotting, sprouting, rooting and bulb weight loss. Post harvest studies also revealed early sowing D1 (25th August) performed better than other sowing dates. Among the treatment combinations, D1V4 (Bhima Super on 25th August sowing) was the best in storage after 3 months of storage so it can be successfully stored for three months after harvesting under Jorhat conditions of Assam
