SUMMARY
field experiment was carried out during Rabi season, 2022-23 at Forage Section Research Farm Department of G&PB, CCS HAU, Hisar to in order to assess the effect of different nitrogen (N) levels on forage yield and quality of promising entries of single cut oat. The experiment was laid out in split plot design with ten promising entries of single cut oat (Seven test entries i.e. HFO-1003, HFO-1009, HFO-1013, JO-08-37, SKO-244, OL-1977, OL-1980 + 2 national checks i.e., Kent and OS-6 + 1 zonal check i.e. OS 403 (North-West Zone, North-East Zone and South zone) in main plot and three nitrogen doses (80, 100, and 120 kg N/ha) in sub plot. Findings revealed that entry OL-1980 recorded highest green and dry fodder yields (482.69 and 87.96 q/ha, respectively) which were on a par with OS-6 and OL-1977. OL-1980 also gave highest per day productivity of green fodder (4.68 q/ ha/day) and dry matter (0.85 q/ha/day) which was statistically at par with entry OS 6 (NC) and OL- 1977. Maximum B: C ratio (2.14) was fetched with entry OL-1980 followed by OS-6 and OL-1977. Highest crude protein content (13.24 %) was estimated with OL-1980 which was on a par with OS-6, OS-403, SKO-244 and JO-08-37. Among different nitrogen treatments, the application of 120 kg N/ha resulted in highest green fodder and dry matter yield (438.69 q/ha and 80.43 q/ha, respectively) which were on a par with 100 kg N/ha but significantly higher than 80 kg N/ha. The maximum crude protein content was also estimated with the application of 120 kg N/ha (13.08 %), which was on a par to 100 kg N/ha but significantly superior over 80 kg N/ha. Maximum B:C ratio (1.91) was also fetched with the application of 120 kg N/ha but it was same with 100 kg N/ha which indicated that nitrogen application was remunerative up to 100 kg N/ha in single cut oat.
