| Abstract | ||||
| A field experiment was carried out at a private Farm in Rowad Village belong to Sahl El-Husseiniya, Sharkia Governorate during the two growing seasons of 2016 and 2017 to study the effect of spraying potassium silicate and adding ammonium thiosulfate (ATS)as soil drenching at three levels on vegetative growth, yield and its components and chemical constituents of eggplant grown under salinity soil( Black Beauty cultivar). The experiment was carried out by using split-plots system in a randomized complete blocks design with three replications. The main plots were arranged with potassium silicate treatments. While, the sub-plots assigned to ammonium thiosulfate levels. The obtained results of this investigation can be summarized as follows: Foliar spraying eggplant plants with potassium silicate levels significantly improved vegetative growth, the yield and its components along with chemical constituents either in the leaves or in the fruits compared with control treatment during both seasons. The highest values of these traits were resulted from using concentration of 6 cm potassium silicate/L in both seasons. Concerning to the effect of ammonium thiosulfate ,it can said that vegetative growth, yield and its components and chemical constituents of either the leaves or in the fruits of eggplant were significantly influenced by different ammonium thiosulfate (ATS) levels adding as drenching around the plants in the both seasons. The maximum values of these characters were produced from using 15 L/fed or 10 L/fed of ATS, respectively in both seasons.While the favourable results on the growth,yield and its components as well as the chemical constituents in the leaves or the fruits were obtained from the interaction between the treatment of foliar spray with 6 cm potassium silicate and adding 15 L/fed from ammonium thiosulfate as soil drenching to obtain the highest results. For that, it could be recommended that foliar spraying eggplant plants grown under salinity soil with 6 cm potassium silicate/L 3 times with using 15 L ATS/fed as soil drenching to enhance vegetative growth characters, yield and its components and chemical constituents of eggplant fruits under the environmental condition of this research. | ||||
