In order to investigate the effect of nitrogen and intercropping patterns on forage quantity of barley and pea, an experiment was arranged as factorial based on Randomized Complete Block Design with three replications during 2011- 2012 in form research of Gonbad Kavous University. Planting pattern levels was sole crop of barley, sole crop of pea, one line of barley and one line of pea, two lines of barley and two lines of pea and three lines of barley and three lines of pea and Nitrogen levels was 0, 25, 50 and 75 Kg/ha. Barley,s cultivar was Sahra and pea was Sungro. Sole crops and intercropping of one line barley and one line pea were planted in four rows and two lines barley and two lines pea and three lines barley and three lines pea were planted in six and eight rows. Results showed that effect of planting pattern, nitrogen and intraction of planting pattern × nitrogen on forage yield were significant (α= 1%). The maximum forage yield with 14.51 and 14.3 ton/ha was belonged to sole crop of barley with consumption of 75 and 50 kg N/ha. The minimum dry weight with 3.76 ton/ha was belonged to sole crop of pea without consumption of nitrogen.
