SUMMARY
A field experiment was conducted to assess the performance of certain promising entries of fodder oats (Avena sativa L.) and different nitrogen levels on yield and quality under single cut system at Research cum Instructional Farm, I.G.K.V, Raipur in Chhattisgarh plains. The experiment consists with ten promising entries of oats viz. OL-1874-1 of PAU, Ludhiana; OL-1876-1 of PAU, Ludhiana; RO-11-1-3 of MPKV, Rahuri; JO-06-23 of JNKVV, Jabalpur; SKO-241 of SKUAST-K, Srinagar; RO-11-1-2 of MPKV, Rahuri; and HFO-806 of CCS HAU, Hisar; and at national check Kent, OS-6 and at zonal check RO-11-1 as a main plot and three nitrogen levels viz. 60, 90 and 120 kg N/ha as a sub plot treatment was laid out in split plot design with three replications. Among different promising entries of oats, OL-1874-1 recorded maximum forage yield (44.9 t/ha), dry fodder yield (9.43 t/ha), forage productivity (0.49 t/ha/day), dry fodder productivity (0.10 t/ha/day), crude protein yield (0.996 t/ha). On the other hand, SKO-241, which was found inferior with respect to grain yield attributes gave the highest content of fodder dry matter (25%). The highest crude protein content of 11.16% was obtained in RO-11-1. As regard to different nitrogen levels, forage yield (34.5 t/ha), dry fodder yield (7.62 t/ha), forage productivity (0.38 t/ha/day), dry fodder productivity (0.08 t/ha/day) and crude protein yield (0.85 t/ha), and crude protein content (11%) increased with 120 kg N/ha but the fodder dry matter showed almost similar performance at 60, 90 and 120 kg N/ha.
Key words: Crude protein, fodder oats, forage yield, nitrogen levels, quality
