An experiment was conducted to study the effect of different cutting management schedules on growth, yield, quality and economics of dual purpose oat, barley and wheat during 2012-13 to 2014-15. The three year pooled data under cutting management revealed significantly higher green forage (54.3 t/ha), dry matter (9.15 t/ha), crude protein (0.93 t/ha), straw yield (10.02 t/ha) and green forage equivalent yield (78.31 t/ha) of oat,respectively. For dual purpose, oat variety RO-19 recorded significantly higher net monetary returns (Rs. 36033/ha) with B:C ratio (2.35) than rest of the crops. Whereas, seed yield (2.48 t/ha) was recorded significantly higher in the wheat crop. As regards to the cutting management, cutting at 70 days after sowing for fodder recorded significantly higher green forage, dry matter and crude protein yield (39.03, 7.12, 0.77 t/ha, respectively) than rest of the cutting managements. The seed and straw yield (2.48 and 9.40 t/ha) was recorded significantly higher in the no cutting for fodder and left for seed only on pooled mean basis; while, cutting at 50 DAS and left crop for seed recorded significantly higher green forage equivalent yield (79.45 t/ha), gross monetary returns (Rs. 63561/ha) and net monetary returns (Rs. 36128/ha) with B:C ratio (2.31). The pH, EC and organic carbon after harvest of crop remained unaffected. The differences are non-significant on pooled mean basis. The available N after harvest was recorded significantly higher i.e. 183.46 kg/ha in Barley crop. The soil available phosphorus (20.62 kg/ha) was recorded in wheat crop. While, available potash remained non-significant on pooled mean basis. As regards cutting management, no cutting for fodder and left for seed recorded significantly higher soil available N after harvest (173.46 kg/ha). The soil available phosphorus (20.78 kg/ha) was recorded at cutting at 70 DAS after sowing and left the crop for seed. The soil available potash remained unchanged due to cutting management on pooled mean basis.
