Abstract
The experiment was laid out in Randomized Block Design with ten treatments viz., T1 (Control), T2 (GA3 10 ppm), T3 (GA3 20 ppm), T4 (GA3 30 ppm), T5 (NAA 25 ppm), T6 (NAA 50 ppm), T7 (NAA 75 ppm), T8 (TIBA 10 ppm), T9 (TIBA 15 ppm) and T10 (TIBA 20 ppm). The results revealed that, the maximum length of main creeper at 60 and 90 DAS (201.78 and 309.23 cm), respectively, number of sub-creeper at 60 and 90 DAS (7.53 and 8.23) and number of leaves/plant at 60 and 90 days after sowing (244.10 and 412.68), maximum chlorophyll content at 45 and 60 days (31.38 and 36.85) and produced the maximum number of male flower (165.75) were recorded with treatment GA3 30 ppm (T4). The TIBA 20 ppm (T10) proved to be most effective for producing the lower node number at which first female flower appears (8.25), maximum number of female flower (19.35) and lowered sex ratio (1: 7.13) and maximum number of fruits (3.00), fruit yield/plant (12.39 kg), fruit yield/ha (619.50 q/ha) and fruit length (24.32 cm). The maximum average fruit weight (4.27 kg/fruit) and fruit diameter (22.71 cm) recorded in treatment T9 (TIBA 15 ppm).
