  To study the effect of cutting irrigation and application of biofertilizer and nitrogen on yield and yield components of corn single cross hybrid, an experiment was carried out in Satloo Agricultural and Natural resources Research Station of west Azarbaijan, 2009-2010. This experiment was arranged as split plot based on Randomized Complete Block Design with three replications.Four irrigation factors including I1, I2, I3 and I4, respectively: cutting irrigations at stem elongation, blossom and seed filling stages and normal irrigation assigned to main plots and fertilizer treatments consisted of Nitoxin + 50% urea (F1 ), Niragin + 50% urea (F2 ), and without biofertilizer application + 100% urea (F3 ) were allocated to sub plots.Results indicated that the effect of cutting irrigations had negative and significant effects on all characteristics; Fertilizer treatments on the other hand had significant effect only on seed numbers per ear, 100 seeds weight and seed yield. The highest seed yield was obtained under normal irrigation and treatment of Nitragin + 50% urea (12320.7 kg/ha and 11100.5 kg/ha) respectively. Manuscript profile
