Abstract

In order to study the effects of Vesicular Arbuscular Mycorrhizae (VAM) fungi, phosphorus and drought stress on nutrient uptake efficiency in wheat, 3 factors of Mycorrhizae (with and without application), phosphorus (0, 6 and 12 g P2O5 per m2), and irrigation (10.5, 24.8, 36.1, 46.2 and 55.1mm water for each irrigation interval) were investigated on wheat (Mahdavi cultivar) with 3 replications based on Hanks et al. (1980). Application of fungus caused a significant increase in phosphorus and potassium uptake efficiency. The effect of phosphorus on above character was also significant at the 1% level of probability. There was not significant difference between application and non-application of fungus in nitrogen uptake efficiency, whereas application of different levels of phosphorus caused a significant difference at the 1% level on this character. Mean comparison of effects of fungus x phosphorus x irrigation on phosphorus uptake efficiency showed that symbiosis of phosphorus, had most phosphorus uptake efficiency (428.7gkg-1). The highest phosphorus uptake efficiency (295 gkg-1) without application of VAM fungi was obtained by use of 55.1 mm water for each irrigation interval and application of 6g P2O5 per m2.Therefore VAM fungi caused a significant increase for phosphorus uptake efficiency in low phosphorus levels
