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.
