Özet

Eggplant (Solanum melongena L.) cv. Pala was grown in the field from March to August 2001 in order to investigate the effects of deficit irrigation on fruit yield and quality (i.e. soluble dry matter, fruit size), leaf relative water content, leaf area index (LAI), leaf chlorophyll concentration, electrolyte leakage, and leaf nutrient composition (N, P, K) in eggplant. Treatments were: (1) well-watered treatment receiving 100% replenishment of A pan evaporation on a daily basis (C); (2) water-stressed treatment receiving 90% replenishment of A pan evaporation at 4-day intervals (WS1); (3) water-stressed treatment receiving 80% replenishment of A pan evaporation at 8-day intervals (WS2); and (4) water-stressed treatment receiving 70% replenishment of A pan evaporation at 12-day intervals (WS3). A total of 1276 mm of water was applied to C treatment, and the seasonal water use of eggplant ranged from 905 to 1373 mm.
