Pant University of Agriculture and Technology, Pantnagar, U.S. Nagar (Uttarakhand) during Rabi season 2007-08 to evaluate the response of integrated nutrient management on nutrient uptake, protein content and seed yield of fenugreek (Trigonella foenum-graecum L.).The experiment was conducted in the randomized block design with three replications.Ten treatments consisting of control (T1) , vermicompost 5 t alongwith Rhizobium + 40 kg N ha(T2), vermicompost 5 t alongwith Rhizobium + 30 kg N ha(T3), vermicompost 5 t alongwith Rhizobium + 20 kg N ha(T4), Rhizobium alongwith vermicompost 5 t ha (T5), Rhizobium alongwith vermicompost 10 t ha(T6), vermicompost 5 t ha(T7), vermicompost 10 t ha(T8) , 40 kg N ha(T9) and Rhizobium inoculation (T10) were tested. Nitrogen content and uptake was observed significantly higher with the application of vermicompost 5 t alongwith Rhizobium + 40 kg N ha.The maximum phosphorus content was observed with the application of Rhizobium alongwith vermicompost 10 t ha. Whereas, uptake of phosphorus was maximum with vermicompost 5 t alongwith Rhizobium + 40 kg N ha. Potassium content (seed and straw) and uptake increased with application of Rhizobium alongwith vermicompost 10 t ha. Protein content and yield increased with integrated nutrient management. Application of vermicompost 5 t alongwith Rhizobium + 40 kg N ha resulted in the highest protein content (21.75%) and yield (449.57 kg ha). Application of vermicompost 5 t alongwith Rhizobium + 40 kg N ha resulted in the highest seed yield (70.69 per cent increase over control). The maximum straw yield (25.01 per cent increase over control) was recorded with application of vermicompost 5 t alongwith Rhizobium + 40 kg N ha.
