A study was conducted to determine forage biomass production. The study was conducted in a 5 x 2 factorial arrangement of treatments in a randomized complete block design (RCBD) with three replications. The first factor was five different seed proportions, i.e. 0, 25, 50, 75 and 100% of oats and the remains vetch for SP1, SP2, SP3, SP4 and SP5, respectively. The sole oat had a seeding rate of Oats 80 kg/ha or 48 gm/plot, and that of sole vetch had a seeding rate of 25 kg/ha or 15 gm/plot. The second factor was either without (P0) or with (P1) phosphorus fertilizer (DAP) application at a rate of 100 kg/ha or 60 gm/plot. The size of the plots was 3 x 2 meters. Seeds were drilled by hand in rows 30 cm apart, spaced approximately 5 cm between plants and covered with soil to about 3 cm depth. Vetch DMY was the highest for SP2 (4.21 t/ha), and the lowest for SP4 (1.66 t/ha). Oats DMY yield was higher for SP4 (4.80 t/ha) as compared to the other seed proportions (range 2.43 to 3.16 t/ha). Phosphorous fertilization failed to induce a significant effect (P>0.05) on the DMY of vetch and oats. The pH of the soil was significantly affected (P<0.05) by seed proportion, phosphorous fertilization and their interaction. Total nitrogen was not significantly (P>0.05) affected by seed proportion, phosphorous fertilizer application and their interaction in this study. The OC was not significantly (P>0.05) affected by seed proportion, but effect of phosphorous fertilizer application and the interaction of the two factors on OC were significant (P<0.05), where as OM content of the soil was significantly affected (P<0.01) by seed proportion, phosphorous application and their interaction.
