In order to investigate the effect of phosphorus fertilizer and spraying Fe chellat in micronutrients absorption rate, rate of proline and soluble carbohydrates in bread wheat and some of its ancestral species in dryland condition, a factorial experiment was conducted with three factors consist of: P fertilizer (in two levels), spraying Fe chellat (in two levels) and different species of wheat (sardari cultivar, Triticum boeoticum, Aegilops speltoides,Triticum diccocoides,Aegilops tauschii) in the form of randomized complete blocks design with three replications in research farm of Agricultural faculty of Ilam University. Results showed that micronutrients absorption rate in different species of wheat was different significantly. Triticum diccocoides had the most rate of phosphorus and cupper absorption, Aegilops speltoides had the most of Mn absorption efficiency and Triticum boiticum had the most rate of Fe absorption. Results showed that in flowering stage application of P fertilizer caused increase in proline and soluble carbohydrates. Sardari cultivar and Aegilops tauschii had the most amount of proline and carbohydrate content. Interaction of P fertilizer factor in different species of wheat was significant on proline and soluble carbohydrates rate. Application of phosphorus, increased proline and soluble carbohydrates rate in crop species of wheat and Aegilops tauschii more than other species.
