A field experiment was conducted at CCS Haryana Agricultural University, Hisar (Haryana) during winter season (rabi) of 2014-15 to study the performance of dual purpose oat, wheat and barley under different cutting management system. Three crops viz. oat, wheat and barley and four cutting management viz. no cutting, cutting for fodder at 50, 60 and 70 days after sowing (DAS) were replicated thrice under split plot design. The varieties used were HJ 8, WH 1164 and RD 2035 for oat, wheat and barley, respectively. The soil of the experimental field was sandy loam in texture with pH 8.6, organic carbon 0.49%, available phosphorus 14.0 kg/ha and available potassium 254.0 kg/ha. Among crops, oat produced the maximum green fodder, dry matter followed by barley. However, wheat produced the maximum grain yield followed by barley. Among different cutting management practices, maximum green fodder and dry matter yield were recorded when cut was taken 70 DAS and then left for grain. Wheat crop produced the highest grain and second highest straw yield and thereby fetched highest B:C ratio (2.16). Based on the results, it could be concluded that among the crops viz. oat, barley and wheat, all the three crops suits for dual purpose but crop selection should be based on the priority of end user. If the priority was to get more green fodder from first cut then oat could be first choice followed by barley and wheat. Besides this, the cutting management schedule needs to be standardized. The green fodder yield increased significantly as the number of days to cut increased from 50 to 70 from sowing. But the grain yield decreased significantly as the cutting schedule was advanced from 50 days onward. Based on the economic analysis, wheat was the most remunerative crop followed by oat for dual purpose. If compared with no cut where remunerations were highest, the cut at 50 DAS was most beneficial.
