Abstract:
A field experiment was carried out at PG Research Block, College of Horticulture, Sri Konda Laxman Telangana State Horticultural University, Rajendranagar, Hyderabad, to assess the “Effect of Plant Growth Regulators on Growth, Yield and Quality parameters in Tomato (Solanum lycopersicum L.) Hybrids under Southern Telangana Zone’’ during Rabi season 2022-23. The experiment was laid out in Factorial Randomized Block Design (FRBD) with fourteen treatments and three replications with two factors viz., factor one consists of two treatments A₁ – Arka Rakshak, A₂ – Arka Samrat and factor two includes seven treatments B₁ – GA₃ @ 20 ppm, B₂ – GA₃ @ 30 ppm, B₃ – NAA @ 20 ppm, B₄ – NAA @ 30 ppm, B₅ – 2,4-D @ 5 ppm, B₆ – 2,4-D 10 ppm, B₇ – Control. Significant difference was observed for all the parameters under study. Results revealed that highest Ascorbic acid (19.34 mg/100 g), T.S.S. (4.38 ⁰brix) and Lycopene (5.27 mg/100 g) was recorded in the treatment combination of T₂ - A₁B₂ - Arka Rakshak + GA₃ @ 30 ppm. While the lowest Ascorbic acid (14.82 mg/100 g), T.S.S. (3.03 ⁰brix) and Lycopene (3.66 mg/100 g) was recorded in the treatment combination of T₁₄ - A₂B₇ – Arka Samrat @ control (3.66 mg/100 gm) compared with all other treatments.
