Effects of Time of Foliar Application of Nitrogen and its Concentrations on the Flower Bud Retention in Pistachio Trees

B. Baninasab, M. Rahemi and A. Javanshah

Abstract:
This study was conducted to test the effects of different concentrations (0, 0.3 and 0.6%) of nitrogen and application dates (May 6, June 17 and July 18) on flower bud retention of pistachio (cv. Owhadi) trees. The results showed that nitrogen significantly increased the flower bud retention, nitrogen level of leaf, current shoot and bud, photosynthesis rate, chlorophyll content and leaf area. Nitrogen was more effective in increasing flower bud retention of pistachio trees when applied at 0.3% on June 17. Abscission of flower buds decreased progressively as nitrogen content in leaf, current shoot and flower bud and also leaf area increased. It was concluded that application of nitrogen to the pistachio trees might be a useful method in decreasing flower bud abscission and increasing crop in the following year.
