A field trial was conducted to study the impact of foliar application of antioxidants and PGRs on growth, yield and quality of tomato (Solanum lycopersicum L.) under valley condition of Garhwal at Horticultural Research Centre, Department of Horticulture, Chauras Campus, Hemvati Nandan Bahuguna Garhwal University, Srinagar, Uttarakhand India, during the summer season of 2024. The objective of the experiment was to find out the effect and best treatment among antioxidants and PGRs on growth, yield and quality of tomato. The results were found to be significant for all the parameters studied. The growth parameters were found to be maximum under T2 (GA3 100 ppm), i.e., plant height at harvest (81.01 cm), primary branches per plant (12.50), days taken to first flowering (27.49), days taken to first fruiting (32.18), and number of flowers per cluster (38.74). On the other hand, the treatment T2 (GA3 100 ppm) showed significant influences on fruit yield per plant (6.48 kg), average fruit weight (33.91 g), fruit yield per hectare (480 q), and fruit length (3.10). From the quality point of view, different treatments showed their impact on different parameters. T2 (GA3 100 ppm) treatment showed highest total soluble solids (5.13°Brix) and vitamin C (27.39mg 100g-1) and T9 (ascorbic acid 100 ppm) revealed maximum titratable acidity (0.47%).
