| Abstract | ||||
| This study was carried out at Sinbillawain district, Dakahlia Governorate, Egypt, during 2022 and 2023 summer seasons to clarify the influence of irrigation periods, soil additions, antitranspirant applying sprays to the foliage treatments, and their interactions on development, yield, and their components, as well as fruit quality of eggplant Sawad Allayl cultivar. The experimental layout was a strip-split plots design in three replications. The vertical-strips were assigned to irrigation periods (irrigation every 10, 15 and 20 days intervals). The horizontal-strips were devoted to soil additions (without, zeolite 500 kg/fed and polymer 30 kg/fed). While, the sub-plots were allocated to applying sprays to the foliage with antitranspirants (without, potassium silicate 2.5 ml/l and chitosan 0.5 g/l. Approximating irrigation periods by irrigation every 10 days, polymer soil addition at 30 kg/fed and applying sprays to the foliage eggplant plants with potassium silicate at 2.5 ml/l produced highest values of growth characters, yield and its components, chemical constituents of fruits. In order to save irrigation water at the same time maintaining highest growth, productivity and fruit quality of eggplant. It could be recommended that irrigation eggplant plants every 15 days besides soil addition with polymer at 30 kg/fed and foliage sprayed with potassium silicate at 2.5 ml/l under the environmental conditions of Sinbillawain district, Dakahlia Governorate, Egypt. | ||||
