Studies on storage behaviour of onion as influenced by pre-harvest treatments


Author(s): VU Raut, Neha Chopde and PN Bhute

Abstract: An experiment entitled ‘Studies on storage behaviour of onion bulbs as influenced by pre-harvest treatments’ was carried out during the academic year 2012-2013 in Post-Harvest Technology Laboratory, Department of Horticulture, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola (M.S.) under ambient conditions in Completely Randomized Block Design with 11 treatments viz., T1 – Carbendazim 1000 ppm + Maleic hydrazide 2000 ppm, T2 – Carbendazim 1000 ppm + Maleic hydrazide 2500 ppm, T3 – Benomyl1000 ppm + Maleic hydrazide 2000 ppm, T4– Benomyl 1000 ppm + Maleic hydrazide 2500 ppm, T5 – Carbendazim 1000 ppm + Streptocycline 200 ppm, T6 – Carbendazim 1000 ppm + Streptocycline 500 ppm, T7 – Carbendazim 1000 ppm + Maleic hydrazide 2000 ppm + Streptocycline 200 ppm, T8– Carbendazim 1000 ppm+ Maleic hydrazide 2000 ppm+ Streptocycline 500 ppm, T9–Carbendazim 1000 ppm + Maleic hydrazide 2500 ppm + Streptocycline 200 ppm, T10- Carbendazim 1000 ppm + Maleic hydrazide 2500 ppm + Streptocycline 500 ppm and T11- Control replicated thrice. The treatments were imposed 2 weeks before harvesting of onion bulbs by spraying uniformly the plants as per the treatments and the bulbs after harvesting and curing used for storage studies. The results revealed that, the pre-harvest spray with carbendazim 1000 ppm + maleic hydrazide 2500 ppm + streptocycline 500 ppm was found most superior treatment than the other treatments under experimentation and significantly minimum PLW (11.88 %), sprouting (5.60 %), black mould (6.00 %) and rotting (5.92 %) were recorded with this treatment when the observations recorded at 120th day of storage.
