Abstract
This investigation was aimed to study the effects of interaction of apex removal (topping) treatments at varying interval leaf stages (4, 5 and 6th leaf stage) and application of gibberellic acid (GA3) at different rates (0, 20 and 40 mg/L) on growth, flowering characters, yield and its components of husk tomato (Physalis pruinosa, L.) cultivar Balady. The obtained results showed that topping at 4 , 5 and 6th leaf stage stimulated growth of basal branches and increased number of flowers which were achieved at the early yield, likewise, application of GA3 either at 20 or 40 mg/L overcame the delaying effect of topping on flowering and at the same time enhanced growth of basal branches. In conclusion total yield increased, by 4th leaf stage of topping under 40 mg/L of GA3 combination, which sassociated with increased number and average weight of fruits.
