Influence of bio regulators on quantitative and qualitative parameters of sweet pepper under controlled condition

The investigation on influence of bio-regulators on quantitative and qualitative parameters of sweet pepper cv. Solan Bharpur under controlled condition was undertaken at Horticultural Research Centre of H.N.B. Garhwal University, Srinagar (Garhwal), Uttarakhand, India during spring-summer season, 2011. The findings for present study revealed that the bio-regulators spray had significant influence on growth, yield and quality. Spraying of NAA at 50 ppm significantly increased the plant height, number of secondary branches, leaf area, days taken to first flower, days taken to 50 per cent flower, number of flower/plant, number of fruit/plant, fruit set per cent, days taken to fruit set, days taken to first picking, duration of marketable fruit, fruit breadth, fruit weight, yield/plant, yield/plot, yield/hectare, number of seed/fruit, 1000 seed weight, specific gravity, TSS while fruit length increased with IAA at 100 ppm. This experiment shows that bio-regulator especially NAA at 50 ppm is very helpful for enhancing the total production of capsicum under controlled condition.
