A field experiment was conducted during winter 2004–05 and 2005–06 at Jobner, Jaipur on loamy sand soil to evaluate the effect of integrated nutrient management on productivity and nutrient uptake of fenugreek (Trigonella foenumgraecum L.) and its residual effect on fodder pearlmillet (Pennisetum glaucum (L.) R. Br. Emend. Stutz.). The experiment consisted of eighteen combinations of integrated nutrient management practices for application of recommended dose of nitrogen (RDN) to fenugreek, i.e. 40 kg/ha, through different sources, viz. control, organic [farmyard manure (FYM), vermicompost (VC) and poultry manure (PM), inorganic] alone or in combinations with or without microbial (Rhizobium) inoculation. Results revealed that integration of 50% RDN through poultry manure (PM)+50% RDN through inorganic sources to fenugreek recorded higher growth attributes, viz. plant stand/m row length, plant height, branches/plant, dry matter accumulation/m row length, nodules/plant and weight of nodules/plant, yield attributes, viz. pods/plant, seeds/pod and test weight, seed yield (1.76 t/ha), biological yield (5.97 t/ha), system productivity (2.95 t/ha) and fodder yield of pearlmillet at all the cuttings. This treatment was also superior in terms of N, P, protein and phenol content (%) in seed as well as in haulm, total N and P uptake and available N and P after the harvest of the crop in both the years over all other combination of integrated nutrient management. However, maximum net returns (60,443) and net returns/rupee invested for the system were fetched with integrated application of 50% RDN through VC + 50% RDN through inorganic sources.
