Abstract: 
A factorial completely randomized design experiment with three replications was carried out in greenhouse to evaluate the phosphorus (P) acquisition and utilization efficiency of 20 wheat genotypes in a river sand fertilized with rock phosphate (RP) and soluble P (PS). Results showed significant differences in shoot dry weight (SDW), shoot P concentration, shoot P content, P acquisition (PACE), P utilization (PUTE) and P efficiency. Marvdasht and Hamun with 8.3 and 5.6 g dry weight showed the highest and lowest response to soluble P fertilizer application, respectively. The average of PACE for all genotypes was 0.04 which Azadi and Karaj1 were the most and least efficient in P acquisition compared to other genotypes. PUTE ranged from 0.6 (Azadi) to 1.12 (Moghan 1) with the average of 0.82 (RP) and 0.31 g DW mg-1 P (PS). Among wheat genotypes, Karaj 1 (4.5%) and Azadi (14.5%) showed the lowest and highest P efficiency, respectively. There was no correlation (R2=0.18) between P efficiency and shoot P concentration of genotypes, but the relationship between P efficiency and shoot P content was highly significant (R2=0.77).
