A field experiment was carried out during rabi 2017-18 at Instructional Farm, Rajasthan College of Agriculture, Udaipur with the objective to study the response of different fodder oat varieties to varying nitrogen levels. The experiment was conducted in factorial randomized block design. The treatments 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) with three replications. The soil of the experimental site was clay loam in texture with low in available nitrogen, medium in phosphorus and rich in potassium. The findings of the experiment indicated that variety JHO-99-2 recorded significantly higher crude protein, ash, ether extract and nitrogen free extract with low crude fibre content during both the cuttings. Similarly, application of 120 kg N/ha produced significantly higher crude protein, crude fibre, ash and ether extract content with less nitrogen free extract. The variety JHO-99-2 gave significantly higher NPK content and its uptake by fodder oat. NPK content and uptake by crop were increased significantly with increase in nitrogen levels and recorded maximum with the application of 120 kg N/ha at first and second cut.
