Effect of different curing methods on storability of onion bulbs


Author(s): VU Raut, Neha Chopde, PT Bhaisare and RS Wankhede

Abstract: The experiment on effect of different curing methods on storage life of onions was conducted at Department of Horticulture, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola. In the treatment T1, field cured bulbs were kept under 50 per cent shade for 12 days and tops removed immediately after harvesting. In the treatment T1, field cured bulbs were kept under 50 per cent shade for 12 days and tops removed immediately after harvesting. In treatments T2, T3, T4 and T5 field cured bulbs were kept under 50 per cent shade for 15 days with topping on 3rd, 5th, 10th and 15th day after harvesting, respectively. In treatment T6, field cured bulbs were kept under 100 per cent shade for 15 days with topping on 15th day after harvest. In treatment T7 and T8, field cured bulbs were kept on tarpaulin under 50 per cent and 100 per cent shade for 15 days, respectively with topping on 7th day after harvest. T9 was control (method usually adopted by the farmers). It was found that post-harvest curing significantly reduced the storage losses. Among the different curing methods, field cured bulbs kept under 50 per cent shade for 15 days and tops removed 15 days after harvest (T5) was found superior with minimum storage losses. The minimum physiological loss in weight (12.24%), sprouting (3.2%), rotting (6.9%) and incidence of black mould (7.80%) with maximum marketable bulbs (82.10%) was noted in this treatment. The curing operation resulted in colour development of onion bulb and highest score (7.4) was recorded in the same treatment.
