Abstract

This study was aimed to evaluate the effects of some pruning systems on the growth of two (Capsicum annuum L.) cultivars. The experiment was designed as Factorial Randomized Complete Block Design (RCBD) each treatment replicated 3 times each with 8 treatments (experimental unit) representing 2 cultivars (California wonder and Biotek), two number of branches (leaving 2 and 4 branches on the main stem) and 2 treatments of apical removal; control (without apical removal) and apical removal of main branches. The highest value of plant height was recorded from California wonder cultivar when pruned on four branches without apical removal and the highest number of sub branches as well as number of fruits, yield.plant-1, yield.plot-1 and yield.ha-1 (40.77, 40.27, 0.89kg, 5.39kg and 47.95ton respectively) were observed from Biotek cultivar, pruned on two branches with apical removal of branches.
