Abstract: A field experiment was carried out during rabi2017-18 at Instructional Farm, Rajasthan College of Agriculture, Udaipur with the objective to study the response of fodder oat varieties to varying nitrogen levels. The treatment comprised of five varieties (Kent, JHO-851, JHO-822, JHO-99-2 and JHO-2000-4) and three nitrogen levels (80, 100 and 120 kg N ha-1) cut twice at 55 DAS and at 50% flowering. The experiment was conducted in factorial randomized block design with three replications. The soil of the experimental site was low in available nitrogen, medium in phosphorus and rich in potassium. The findings of an experiment indicated that variety JHO-99-2 and application of 120 kg N ha-1 produced significantly higher plant height, number of tillers m-1 row length, dry matter accumulation m-1 row length and leaf stem ratio at first and second cut. Variety JHO-99-2 gave significantly higher total green fodder yield (70.5 t ha-1), total dry fodder yield (15.5 t ha-1) and production efficiency 594.9 and 786.8 kg ha-1 day-1 at first and second cut, respectively. Application of 120 kg N ha-1 gave the maximum green fodder yield (32.1 and 37.0 t ha-1) and dry fodder yield (7.1 and 8.2 t ha-1) at first and second cut. The highest net return (₹ 75874 ha-1) and B C ratio (2.54) was recorded with JHO-99-2. Application of 120 kg N ha-1 fetched the maximum net return (₹ 73436 ha-1) and B C ratio (2.43) respectively.
