SUMMARY
Field experiment was conducted to study the performance of promising entries of oat and effect of nitrogen levels on yield and yield parameters. Results obtained from this experiment indicated that the significant and highest plant height (129.4 cm) was recorded by variety SKO-188 over all varieties of oat. However, lowest plant height (90.8 cm) of oat plant was recorded by variety OS-377. Maximum tillers of oat per row length (83.5) were recorded by two varieties viz., JO-03-97 and SKO-188 over all other varieties UPO-10-1, OS-377, JHO-10-2 and OL-125 (NC). Variety OS-6 (NC) recorded the highest green fodder yield of oat (401.3 q/ha) followed by JO-03-97 (385.6 q/ha) and least by OS-777 (299.7 q/ha). Variety OS-6 (NC) also recorded the highest dry fodder yield (82.8 q/ha) followed by UPO-10-2 (79.6 q/ha) and least by OS-777 (57.8 q/ha). Highest protein content (14.7%) in oat was recorded by variety JHO-10-2 closely followed by SKO-170 (14.6%) and least by JO-03-97. Whereas highest protein yield was recorded by variety SKO-170 (10.6 q/ha) and least by OS-777 (8.3 q/ha). Application of nitrogen @ 120.0 kg/ha significantly increased the oat plant height from 89.9 to 126.8 cm, tillers row length/m from 68.6 to 88.1, green fodder yield of oat from 253.4 to 416.1 q/ha, dry fodder yield from 52.8 to 89.2 q/ha, protein content from 11.9 to 13.6 per cent and protein yield from 6.3 to 12.1 q/ha, respectively, over 40.0 and 80 kg N/ha.
