An experiment was conducted at Buffalo Research Institute Pattoki to study the effect of varying levels of nitrogen fertilizer on oat fodder yield, dry matter yield and dry matter percentage. Different levels of nitrogen: T0, O; (control) with no phosphorous and potassium, T1, 0; T2, 70; T3, 92; T4, 114; T5, 136; T6, 158 kg per ha along with a constant dose of triple super phosphate (84 kg per ha) and potassium sulphate (62 kg per ha) were applied. Analysis of variance indicated a significant effect of nitrogen levels on all the parameters studied. Maximum fresh fodder yield (77.11 t per ha) was obtained with the application of 114 kg per ha nitrogen. Whereas minimum fresh fodder yield (55.56 t per ha) was obtained when no fertilizer (nitrogen, phosphorous and potassium) was applied. Higher doses of nitrogen (136 or 158 kg per ha) adversely affected the fresh fodder yield.
