Abstract:
The experiment was conducted at the Sant Kabir College of Agriculture and Research Station, Kabirdham (C.G.), during the rabi seasons of 2017–18 and 2018–19 in the Chhattisgarh plains to ascertain the quality parameters of rabi onions as effected by various pruning techniques, GA3 foliar spray, and transplant densities. Three factors, including pruning (P0- no pruning, P1- leaf pruning, P2- root pruning, and P3- leaf and root pruning), two levels of GA3 application (G0- no GA3 application and G1- GA3 at 150 ppm), and three levels of transplant density (D1- 20X15 cm, D2- 20x10 cm, and D3- 15X10 cm) comprised the treatments. The outcome showed that transplant densities, GA3 application, and pruning techniques all significantly impacted onion quality parameters. While the minimum bolting percent was recorded in P1G0D3 i.e. leaf pruning, no GA3, and planting densities (D3- 15X10 cm), and the maximum bolting percent was recorded in treatment P0G1D1 i.e. no pruning, GA3 150 ppm, and spacing D1- 20X15 cm, respectively, these treatments had different effects on the dry weight of the bulb, neck diameter, and ascorbic acid content.
