SUMMARY
An experiment was carried out during rabi season, 2019-20 at Forage Research Farm Department of Genetics and Plant Breeding, CCS Haryana Agricultural University, Hisar (Haryana) to access the performance of promising entries of multi cut oat to different levels of nitrogen. The experiment was conducted in split plot design with 16 treatments combinations viz., four promising entries (Two entries i.e., OL-1874 and JO-05-304 along with two National checks i.e., UPO-212 and RO-19 of multi cut fodder oat in main plot and four nitrogen levels (35, 70, 105 and 140 kg N/ha) in sub plot with three replications. Results revealed that growth parameters, green fodder and dry matter yield were recorded highest with entry UPO-212. However, highest crude protein content was recorded with entry OL-1874 (9.18%) which was significantly higher than all other entries. Maximum net returns and B: C were fetched with entry UPO-212 followed by RO-19 and OL-1874. Growth parameters, green fodder and dry matter yield were recorded highest with 140 kg N/ha which were statistically at par with 105 kg N/ha. Furthermore, crude protein content (9.41%) and crude protein yield (14.08 q/ha) were also recorded highest with 140 kg N/ha which were statistically at par with 105 kg N/ha. Maximum net returns (19263 Rs/ha) and B: C (1.41) were recorded with 140 kg N/ha followed by 105 kg N/ha.
