SUMMARY
An experiment was conducted during rabi season, 2018-19 at Forage Research Farm Department of Genetics and Plant Breeding, CCS Haryana Agricultural University, Hisar (Haryana) to study the effect of N levels on yield and quality of promising entries of oat. The experiment consisted of 40 treatment combinations viz., 10 promising entries (Seven entries i.e. SKO-229, HFO607, HFO-525, JO-05-7, OL-1869-1, OL-1861, OL-1862 + 2 national checks i.e. Kent and OS-6 + 1 zonal Check i.e. OL-125 (North West Zone) of single cut fodder oat and four nitrogen levels (30, 60, 90, and 120 kg N/ha). Results showed that growth parameters, green fodder and dry matter yield were recorded highest with entry JO-05-7. However, crude protein content was recorded highest with entry HFO 607 and OL-125 (9.42 %) which was statistically at par with JO-05-7. While, crude protein yield was recorded highest with entry JO-05-7 (16.6 q/ha) which was significantly higher than rest of entries. Maximum net returns and B: C ratio was fetched with entry JO-05-7 followed by OL-1861. Growth parameters, green fodder and dry matter yield were recorded highest with 120 kg N/ha which
were statistically at par with 90 kg N/ha. Furthermore, crude protein content and crude protein yield were also recorded highest with 120 kg N/ha (9.08 % and 14.1 q/ha, respectively) which were statistically at par with 90 kg N/ha. Maximum net returns and B: C ratio was recorded with 120 kg N/ha followed by lower levels of nitrogen.
