Field experiment was conducted during two consecutive Kharif seasons at Instructional Dairy Farm of G.B. Pant University of Agriculture and Technology, Pantnagar to evaluate the effect of intercropping and different sources of nitrogen on nutrient (NPK) content and uptake of sweet sorghum and phillipesara. The experimental results showed that the uptake of all nutrients and content of nitrogen of phillipesara due to intercropping reduced significantly over sole crop while content and uptake of all nutrients reported to be higher due to all the integrated sources of nitrogen compared to 100 percent nitrogen through inorganic fertilizer. In sweet sorghum inter cropping of phillipesara exhibited the superiority over sole sweet sorghum in terms of content and uptake of all nutrients (NPK), but this increase was significant only for the content and uptake of phosphorus. The sources of nitrogen significantly influenced the uptake of nitrogen and potassium. Total uptake of nitrogen, phosphorus and potassium by mixed fodder was significantly higher when 50 percent nitrogen through inorganic fertilizer + 50 percent through vermicompost (F3) was applied to intercropping system. However, application of 100 percent nitrogen through inorganic fertilizer (F1) caused significant reduction in content and uptake of all nutrients during both the years.
