Abstract : The effect of different irrigation intervals on tree production and fruit quality of 15-year-old Hindi mango trees was investigated in a field experiment on sandy soil in Tahreer Province, Egypt. Generally 25 and 37 irrigations per year produced a similar response, resulting in better tree growth and fruit yield and quality (higher fruit weight and volume, and pulp concentration; lower peel concentration and seed:fruit ratio) than 18 irrigations. Available soil water reached approx. 2/3 of field capacity at an irrigation frequency of 37 per year, and approx. 1/3 of field capacity with 25 irrigations per year. It was concluded that the number of irrigations may be reduced from 37 to 30 without any effect on fruit yield or quality.
