Eggplant (Solanum melongena L.) is one of the important summer vegetable crops of the Solanaceae family due to its high content of carbohydrates, protein and minerals i.e. N, P, K and Fe as well as vitamin C. The performance of Eggplant (Solanum melongena L.) to foliar spray with potassium (0, 1, 2 and 3 g·l-1) and liquorice extract (0, 2, 4 and 6 g·l-1) were investigated in summer 2013 and 2014 seasons at Ras Sudr research station farm, South Sinai governorate on a salinity soil under drip irrigation system. The effects of the experimental factors on plant growth parameters (height, leaf number, branch number, fresh and dry weight), leaf chlorophyll content, leaf minerals (N, P and K), yield parameters such as, fruit number/plant, fruit weight, total yield per feddan (0.42 ha) were evaluated. The results proved that the foliar application with potassium and liquorice extract produce a significant increase in all parameters under study compared to the control. The foliar application of 2 g·l-1 potassium plus 6 g·l-1 liquorice extract gave the highest values of vegetative growth, mineral values of the leaves, yield and its components.

The influence of chelated iron (0, 250 and 500 mg·L–1 as Fe-EDDHA 6%) and silicon (0, 2, 4 mmol·L–1 as K2SiO3) on the yield and quality of tomato (Solanum lycopersicum L.), Strain B cultivar, were investigated under semi-arid conditions in Ras Sudr region, Egypt, in years 2013–2014. A significant influence of chelated iron and silicon applications on tomato growth, yield and quality were observed. The highest plant growth, leaf mineral contents (N, P and K), vitamin C and Ca contents in fruit, fruit firmness, early and total yield were observed in plants which treated with 500 mg·L–1 chelated iron and 2 and 4 mmol·L–1 silicon. Meanwhile, these treatments decreased the proline content of leaves and T.S.S content of fruit.
