SUMMARY

In view of the increasing demand for fodder, there is urgent need to maximize fodder production
within the existing cropping systems. With this objective a field experiment was carried out in temperate environment during rabi seasons of 2009-10 and 2010-11 on silty clay loam soil to determine the impact of different sowing dates, fertility levels and cutting managements on growth, yield and quality of fodder oat. The treatments comprised of three sowing dates viz. 20 September., 30 September and 10 October; three fertility levels viz., 150:70:40, 125:60:30 and 100:50:20 kg N:P2O5:K2O kg/ha and two cutting management viz., single cut at 50% flowering and double cut on 15 December and 50% flowering stage. Late sowing resulted in poor crop growth and reduced green fodder yield to the tune of 42%. Green fodder yield (36.2 t/ha) and nutrient uptake were higher with the application of 150:70:40 N:P2O5:K2O kg/ha. Double cutting practice produced more green fodder yield to the tune of 15.6 % over single cut crop.
