This research evaluated the effect of seed priming (hydropriming and non-priming or check) on nitrogen and phosphorus uptake and the yield of 10 wheat varieties and genotypes including V1- Sardari, V2- Azar-2, V3- Homa, V4- Rasad, V5-Ohadi, V6-Maning/sdv1/Dougu 88, V7-Sauleshu#44/TR810200 V8-Fantasia loadesskaya /ICWH860031, V9-ISD-75-3-1/Mo88/PRL/VEE#6/4/ GHURABS-3/ AHGAF//MXC/TOB and V10-Unknown-11. This study was conducted in three replications as a strip plot on randomized complete block design at the Dryland Agricultural Research Institute, Maragheh, Iran in two years (2011-2012). Measured characteristics were the percentage of emergence seedlings, green cover percentage at flowering, plant height, yield and yield components, harvest index, productivity degree, rainfall productivity index, N and P uptake. Results showed that the means of hydropriming was superior to non-primed (control) and there were significant differences between wheat genotypes in terms of the percentage of emergence seedlings, green cover percentage at flowering, plant height, days to ripening, spike length, no spike/m2, seeds/spike and biological yield. So considering the differences between wheat genotypes in terms of the reactions to hydropriming seem, this method could be effective on improving the seedling vigor, establishment and increasing the yield of the studied wheat genotypes, P and N uptake at cold and dry lands similar to the tested area.
