Abstract: Oat (Avena Sativa L.) is most important rabi fodder crop and is suitable for cultivation under wide range of agro-ecological climates. It serves as an excellent source of soft, palatable and nutritious fodder rich in protein, phosphorus, cellulose, hemi-cellulose, neutral detergent fiber, acid detergent fiber, vitamins and iron. It can be used as as straw, hay and silage. Its grains are particularly used as feed for horses, sheep and poultry. There are several factors which affect growth, productivity and quality of forage oat, all nitrogenous fertilizer is one of the major components. Muti cut oat cultivars are heavy feeder of nutrient and remove large amount of nutrients from the soil. The field experiment conducted to evaluate the effect of nitrogen level in different varieties on growth, yield and quality of fodder oat (Avena sativa L).A field experiment was conducted during Rabi season 2012-13 at forage Research Field, Dept. Of Genetics and Plant Breeding, Birsa Agriculture University Kanke Ranchi (Jharkhand) to evaluate the effect of nitrogen levels on multi cut oat varieties. Green forage yields increases with increasing nitrogenous fertilizer levels. JHO-12-3 exhibited higher green forage, dry matter and crude protein yields. Application of 80 kg N/ha resulted in significantly highest green forage yield (566.67q/ha). Dry matter yield (45.46 q/ha), and crude protein yield (4.37q/ha).Plant height and leaf: stem ratio increased significantly up to 80 kg N/ha.
