Abstract:
The present investigation was carried out at Regional Horticultural Research Station, ASPEE College of Horticulture and Forestry, Navsari Agricultural University, Navsari, Gujarat during kharif, 2016. The experiment involved fourteen different treatments 4-CPA 20 ppm (T1), 4-CPA 30 ppm (T2), 4-CPA 40 ppm (T3), 2,4-D 2.50 ppm (T4), 2,4-D 5.00 ppm (T5), 2,4-D 7.50 ppm (T6), 4-CPA 20 ppm followed by GA3 (30 ppm) within 24 hours (T7), 4-CPA 30 ppm followed by GA3 (30 ppm) within 24 hours (T8), 4-CPA 40 ppm followed by GA3 (30 ppm) within 24 hours (T9), 2,4-D 2.50 ppm followed by GA3 (30 ppm) within 24 hours (T10), 2,4-D 5.00 ppm followed by GA3 (30 ppm) within 24 hours (T11), 2,4-D 7.50 ppm followed by GA3 (30 ppm) within 24 hours (T12), Control- No spray (T13), 4-CPA 30 ppm- Inflorescence dipping (T14) which was laid out in a Randomized Block Design with three replications. Among different levels of treatment, 30 ppm 4-CPA (Inflorescence dipping) exhibited maximum plant height of 203.47, 251.73 and 306.67 cm at 120, 180 days after planting and at final picking, respectively whereas, control had maximum leaf area (843.33 cm2). Plants treated with 30 ppm 4-CPA (Inflorescence dipping) were found to be superior to all other treatments for majority of the reproductive parameters like fruit set percent (72.50), fruits per cluster (5.80) and number of fruits per plant (58). The superiority of 4-CPA at the rate of 30 ppm (Inflorescences dipping) was also reflected by tomato plants in terms of significantly maximum fruit yield per plant (4.95 kg) as well as fruit yield per m2 (12.69 kg)except average fruit weight. Subsequently, economic analysis of investigation revealed T14 (30 ppm 4-CPA-Inflorescence dipping) as highly remunerative treatment exhibiting BCR of 0.85 with net realization of Rs. 116629.00.
