SUMMARY
A field experiment was conducted during rabi 2013-14 at Instructional Farm, Rajasthan College of Agriculture, Udaipur. The experiment comprised combinations of four irrigations and three nitrogen levels. Thus, all 12 treatments were evaluated in split-plot design with three replications keeping irrigation in main and nitrogen in sub-plots. The results indicated that application of irrigations produced significantly higher crop growth rate and dry fodder yield as well as available soil nitrogen after harvest of fodder oat crop. Similarly, addition of 110 kg N/ha significantly enhanced the crop growth rate and dry fodder yield as well as available soil nitrogen after harvest of oat crop. Application of irrigation and nitrogen did not significantly affect relative growth rate of fodder oat (Avena sativa L.) during the year of experiment.
