GA and NAA affect various aspects of plant physiology, mainly vegetative, flowering and quality attributes 3 including yield. A field experiment was carried out during 2020-21 at vegetable farm of CSKHPKV, Palampur, Himachal Pradesh to evaluate the effects of foliar-applied plant growth regulators gibberellic acid (GA ) and 3 Naphthalene Acidic Acid (NAA) on tomato hybrid Palam Tomato Hybrid-1. Significant impact of GA and 3 NAA at different concentrations was observed on yield and quality parameters of tomato. Among the different treatments plant growth regulators GA @75 ppm resulted maximum number of fruits per plant, fruit weight 3 and marketable yield per plant, marketable yield per m2 area, ascorbic acid content plant height and minimum number of days to 50 % flowering.

GA and NAA affect various aspects of plant physiology, mainly vegetative, flowering and quality attributes 3 including yield. A field experiment was carried out during 2020-21 at vegetable farm of CSKHPKV, Palampur, Himachal Pradesh to evaluate the effects of foliar-applied plant growth regulators gibberellic acid (GA ) and 3 Naphthalene Acidic Acid (NAA) on tomato hybrid Palam Tomato Hybrid-1. Significant impact of GA and 3 NAA at different concentrations was observed on yield and quality parameters of tomato. Among the different treatments plant growth regulators GA @75 ppm resulted maximum number of fruits per plant, fruit weight 3 and marketable yield per plant, marketable yield per m2 area, ascorbic acid content plant height and minimum number of days to 50 % flowering.
