SUMMARY
A field study was carried out during rabi season, 2019-20 at Forage Section Research Farm Department of G&PB, CCSHAU, 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 included 32 treatment combinations including eight promising entries of single cut fodder oats (Five entries i.e. JO-05-09, HFO- 529, HFO-718, SKO-240, OL-1896 + 2 national checks i.e., Kent and OS-6 + 1 zonal check i.e. RO-11-1 (North West Zone) and four nitrogen doses (30, 60, 90, and 120 kg N/ha). Findings revealed that entry SKO-240 had the highest growth characteristics, green fodder and dry matter yield. The highest crude protein content (9.28 %) was found with HFO-718 which was significantly higher than all other except RO-11-1, HFO-529 and Kent, whereas crude protein yield was not influenced sign ificantly by different entries. Maximum net returns (61635 Rs/ha) and B: C (2.67) was fetched with entry SKO-240 followed by Kent and HFO-529. Among different nitrogen treatments, 120 kg N/ha level gave highest values for growth parameters, dry matter and green fodder yield. Moreover, 120 kg N/ha level was found to have the greatest crude protein yield and content (9.41 % and 16.68 q/ha respectively), both of which were statistically at par to 90 kg N/ha. With 120 kg N/ha level, the highest net returns and B: C ratio were obtained, followed by lower levels of nitrogen.
