A field study was conducted to know the effect of field application of salicylic acid, azoxystrobin and cycocel on storage behavior of onion cv. Arka Kalyan during kharif season of 2016-17 at College of Horticulture, Bagalkot. The experiment was laid out in Randomized Complete Block Design, with 12 treatments and 3 replication. The harvested bulbs were kept in storage for 4 months at ambient condition during which various physical parameters including sprouting and chemical parameters like pyruvic acid and total soluble solids were analysed. The reduction in the mean sprouting i.e., 2.26 per cent was observed in bulbs with salicylic acid at 2 mM (seedling dip and foliar spray 60+90 DAT), azoxystrobin at 0.1% (foliar spray at 60+90 DAT) and cycocel at 2500 ppm (foliar spray at 90 DAT), bulbs treated with salicylic acid at 2 mM (seedling dip and foliar spray 60+90 DAT), azoxystrobin at 0.1% (foliar spray at 60+90 DAT) exhibited maximum mean pyruvic acid content 8.71 µmoles/g during prolonged storage of 120 days. The bulbs treated with salicylic acid 2 mM (60+90 DAT), azoxystrobin 0.1% (60+90 DAT) and cycocel 2500 ppm (90 DAT) exhibited maximum total soluble solids. Thus in the present investigation the combined application of salicylic acid, azoxystrobin and cycocel in field reduced sprouting, increased pyruvic acid and total soluble solids in onion cv. Arka kalyan during prolonged storage period.
