An experiment has been carried out in the Department of Horticulture, Janta College, Bakewar, Etawah (UP) India, during two cropping seasons in split plot design, using cultivars viz., cv. Poshita and cv. JA - 20 as main plot. Two planting distance 30 x 30 cm and 30 x 20 cm were used as sub plot. These plants were raised in nursery bed and transplanted after 30 days of sowing. After 30, 60 and 90 days of transplanting the plants were sprayed with IAA 100 ppm, IAA 200 ppm, GA 50 ppm, GA 100 ppm, CCC 2000 ppm and CCC 3000 ppm solutions. In control they were sprayed with distilled water (sub sub-plot). Results abstracted that cv Poshita took more number of days for 50 % flowering and maturity as compared to cv. JA – 20. However, cultivar JA – 20 produced significantly higher number of berries per plant with higher seed yield as compared to cv. Poshita. Stand geometry did not have any significant effect on days to 50 % flowering and maturity. Planting distance 30x30 cm produced higher number of berries and seed yield per plant, although 30 x 20 cm planting distance produced significantly higher seed yield per plot and per hectare. All concentrations of plant growth regulators increased seed yield. GA 100 ppm took minimum days for 50 % flowering and maturity. The maximum number of berries and seed yield ware recorded from IAA 200 ppm treated plants.
