SUMMARY

An investigation was carried out during rabi 2013-14 at Instructional Farm, Rajasthan College of Agriculture, Udaipur with the object to evaluate the quality and economic of oat (Avena sativa L.) var. kent with irrigation and nitrogen levels. The experiment comprised combinations of four irrigations and three nitrogen levels. Thus, 12 treatments were evaluated in split-plot design with three replications. In the main plots, there were irrigations and nitrogen levels were kept under sub-plots. The results indicated that the application of five irrigations and 110 kg N/ha produced significantly higher nitrogen 314.49 and 309.94 kg/ha, crude protein 1965.59 and 1937.13 kg/ha, crude fibre 5271.72 and 5061.22 kg/ha, ether extract 308.28 and 303.25 kg/ha, mineral matter 1290.18 and 1277.18 kg/ha, nitrogen free extract 8759.00 and 8877.58 kg/ha and total digestible nutrient 12688.15 and 12595.72 kg/ha. In irrigation treatments higher gross return Rs. 83222/ha and net returns Rs. 69032.12/ha as well as B:C 3.28 were recorded with five irrigations. Gross return, net returns and B : C of oat increased with increasing level of nitrogen and highest values were recorded with 110 kg N/ha were Rs. 78477/ha, Rs. 60651.91/ha and 3.01, respectively.
