Studies on Training Systems and NAA Application on Bell Pepper Production in Polyhouse

Capsicum (Capsicum annuum L.) is an important off-season vegetable crops grown in the mid-hills of Himachal Pradesh. Production and productivity of this crop is low because of high flower and fruit drop. The present investigation was carried out to find out the best training system and an appropriate concentration of naphthalene acetic acid (NAA). Two-stem training system was the best for most traits except, number of flowers per plant and days to first picking which were best under control, i.e., on plants not trained at all. Two sprays of NAA @ 15 ppm proved best for plant height, total number of flowers per plant, per cent flower drop, per cent fruit set, days to first picking, number of fruits per plant, fruit weight and total yield per plant.
