AbstractTo study the effect of water stress and exogenous application of glycin and salicylic acid mixture on the growth and production of Eggplant (Solanum melongena L.) a factorial experiment with RCBD design was carried out. Water stress factor involved three levels (irrigation with 72, 46.8, 21.6 l.day-1). Two levels of exogenous application of glycin and salicylic acid mixture (spraying with water only and spraying with a mixture of 100 mg. l-1 glycin and 100 mg. l-1 salicylic acid). Solanum melongena L. Vary Black beauty seedlings planted in a silt clay loam soil. Drip irrigation system type T.Tape was used. Chemical fertilizers was used. The first application was one month after planting and the second application was two weeks later. Chlorophyll was measured using Spad-502 meter plus , shoot diameter was measured using vernair , relative water content, the total product and water use efficiency were measured . Results showed significant increase for the first irrigation level W1 compared with W2 and W3 for all indicators. Interacted treatment W1A2 showed significant increase compared with other treatments.
