| Abstract:
Thompson Seedless, the most popular grape variety in Iran, is grown for table use, raisin and juice production. Due to a decrease in rainfall in different areas of the country, possibilities of continued grape growing in dry and semi-dry conditions was to be investigated. Therefore, Thompson Seedless was planted under rain fed conditions using a randomized complete block design with two factors including three depths of planting (60, 90 and 120 cm) and three irrigation schedules (without, once and twice annually), replicated three times within a factorial treatment arrangement. Observations were made over a period of 4 years. The results revealed that in spite of low annual rainfall (250 mm) grape growing under rain fed conditions was possible. Influence of depth of planting on yield was significant, and maximum yield was obtained in 120 cm depth. Influence of irrigation schedule on yield was not significant. | |
