Abstract: A two year study was conducted to establish effects of a commercial preparation (BA plus GA4+7) called accel, on growth and yield of hot pepper. Five concentrations: 0, 5, 10, 15, 20 and 25 mg L-1 of the preparation were used. Concentrations of 10, 15, 20 and 25 mg L-1 significantly (p<0.001) increased yield in a two year pooled data. Accel treatment did not significantly affect number of fruits, number of branches and plant height. The increase in yield due to accel treatment was associated with significant increase in fruit fresh weight (p<0.001) and length (p<0.001). Therefore the increase in yield was attributed to increase in fruit size. Accel application has the potential to be used as a management practice in greenhouse production of hot pepper.
