Abstract

The present investigation on “Effect of potassium levels, sources and time of application on storage life of onion var. ArkaKalyan” was carried out at the College of Horticulture, Bagalkot, Karnataka during Kharif season crop of 2015 and 2016.The physiological loss in weight and rotting and sprouting of onion bulbs was minimum in 200 per cent RDK (19.25 and 13.91%, respectively) and maximum was recorded in 100 per cent RDK (23.40 and 18.13%, respectively). The marketable bulbs of onion was recorded highest in 200 per cent RDK (77.51%) and lowest marketable bulbs was recorded in 100 per cent RDK (71.96%) followed by 175 per cent RDK. The physiological loss in weight and rotting and sprouting of onion bulbs was minimum in potassium sources as SOP (21.12 and 15.09%) over MOP (22.60 and 16.50 per cent respectively). The marketable bulbs of onion was highest in potassium sources as SOP (76.01%, respectively) over MOP (74.43%). The increased marketable bulb yield and reduced the physiological loss in weight and rotting and sprouting onion bulb with the application 50 per cent potassium at transplanting and 50 per cent K at 30 DAT over 100 per cent potassium at transplanting.
