Abstract:
A field experiment was carried out during 2015-16, at the Horticulture Research Center of Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut to find out the impact of foliar application of different levels of GA<sub>3</sub> and NAA on reproductive and quality attributes of tomato cv. Pusa Rohini. The different treatment concentration tested were NAA (15, 20, 25 and 30 ppm), GA<sub>3</sub> (20, 30, 40 and 50 ppm) and control (distilled water spray). All variables parameters related to yield and quality parameters were significantly influenced by different concentrations of the plant bio-regulators. Results revealed that among all the treatments, the foliar application of GA<sub>3</sub> (50 ppm) registered significantly higher reproductive aspects viz., number of cluster per plant (7.07), number of fruit per cluster (6.73), number of fruit per plant (20.60), fruit set (65.09 %), fruit length (4.75 cm), fruit diameter (5.05 cm), fruit weight (61.95 g) and yield (531.74 q/ha). Themaximum TSS (4.93ËšB) was recorded with the foliar application of GA3 (50 ppm), while minimum acidity per cent (0.463) in fruits was recorded under the foliar spray of NAA @ 25 ppm.
