Abstract:
A field trial was carried out at farm of Sant Kabir College of Agriculture and Research Station, Kawardha (C.G.) to assess the quality parameters of rabi onion as influenced by seedling pruning, Gibberellic acid and transplant densities during rabi season 2017-18 and 2018-19 under Chhattisgarh plains. The treatments comprised of 24 treatments which include four methods of pruning (i.e. no pruning, leaf pruning, root pruning and leaf and root pruning), two level of GA₃ (without GA₃ application and GA₃ at 150 ppm) and three level of transplant densities (20 x 15 cm, 20 x 10 cm and 15 x 10 cm). Among the seedling pruning, the quality parameters was recorded significantly higher under P₁ i.e. (leaf pruning) during both the year i.e. Total Soluble Solids (12.72 and 12.76 Brix^o), Sulphur content in bulb (8.44% and 8.42%), Chlorophyll content “a” (0.54 and 0.57) and “b” (0.67 and 0.78). Among GA₃ application the quality parameters was recorded significantly higher under G₁ i.e. (GA₃ 150 ppm) during both the year i.e. Total Soluble Solids (12.36 and 12.40 Brix^o), Sulphur content in bulb (8.63 and 8.51%), Chlorophyll content ‘a’ (0.50 and 0.51) and ‘b’ (0.60 and 0.64). Among transplant densities the quality parameters was recorded significantly higher under D₁ i.e. (20 x 15 cm) during both the year i.e. Total Soluble Solids (12.14 and 12.12 Brix^o), Sulphur content in bulb (8.07 and 8.01%), Chlorophyll content “a” (0.48 and 0.50) and ‘b’ (0.55 and 0.62). Where in case of interaction the treatment P₁G₁D₁ i.e. (leaf pruning, 150 ppm GA₃ and 20 x 15 cm spacing) recorded maximum value during both the year on the basis of mean data.
