Increasing biodiversity in wheat producing systems is a key element for improving sustainable wheat production. In order to find out the best combination of two common used wheat varieties, an experiment was conducted at Research Station, Faculty of Agriculture, Ferdowsi University of Mashhad, Iran, in 2009-2010 and 2010-2011. The two wheat varieties (Falat and Orom) were sown based on a Randomized Completed Block Design with 12 treatments and three replicates. The treatments included in different row cropping patterns of Falat and Orom (100-0, 75-25, 50-50, 25-75, 0-100, 25-175, 175-25, 50-50, 150-50, 75-125, 125-75 and 100-100). Results of first year experiment showed that the highest grain and biological yield were obtained in sole cropping systems, although there were no significant differences between other cropping systems. The highest grain yield (3136 kg ha-1) was obtained in cropping with the ratio of 75:25 Falat vs. Orom treatment which was 29 and 12.5 percentages more than their sole cropping. Our results revealed that row cropping of different wheat varieties can produce promised grain yield in two years.
