Abstract:
The experiment was undertaken to determine the growth and yield parameters of rabi onion as effected by different pruning methods, GA₃ foliar spray and transplant densities at Research field of Sant Kabir College of Agriculture and Research Station, Kabirdham (C.G.) during rabi season 2017 -18 and 2018- 19 under Chhattisgarh plains. The treatments comprised of three factors i.e. Pruning (P₀- no pruning, P₁- leaf pruning, P₂- root pruning and P₃- leaf and root pruning), two level of GA₃ (G₀- no GA₃ application and G₁- GA₃ at 150 ppm), and three level of transplant densities (D₁- 20X15 cm, D₂- 20x10 cm and D₃- 15X10 cm). The result demonstrated that pruning methods, GA₃ application and transplant densities had significant effects on growth, yield component and yield of onion. The interaction effect of P₁G₁D₁ i.e leaf pruning, GA₃ 150 ppm and spacing D₁- 20X15 cm was effective in increasing plant height, number of leaves per plant, equatorial diameter, neck diameter and weight of bulb, while the minimum plant height, number of leaves per plant, equatorial diameter, neck diameter and weight of bulb was recorded in minimum planting densities (D₃- 15X10 cm) without pruning and no GA₃ application.
