Abstract
Two greenhouse experiments were carried out at Army Farm, at El-Amria region, Alexandria, Egypt, during the two seasons of 2016-2017 and 2017-2018. To investigate the effect of water regime, pruning system and potassium silicate on the growth, fruit yield and physiological responses of sweet pepper plants (Gavotte F1 cv.), grown in calcareous soils, under drip irrigation in greenhouse.
The experimental design used was the split-split-plot system in a Randomized Complete Blocks Design each experiment included 36 treatments, which were the combinations of four potassium silicate concentrations (0, 250, 500 and 1000 mg l-1) under three pruning systems (without pruning, left 2 and 3 main stems plant-1) under three water regimes (30, 50 and 70% from the available soil water).
The results showed that sweet pepper plants that irrigated at of 30% of depletion ratio and pruned by Holland system with left 2 stems per plant and spraying the growing plants with the highest concentration of potassium silicate (1000 mg l-1) might be considered as an appropriate treatment combination for achieving higher exportable and total fruits yield as well as saving irrigation water up to 60 % and maximum water use efficiency of sweet pepper plants.
