A field experiment was conducted during kharif 2006 at farmer's field, Ghatolia (Kalakh), Jobner. The soil was loamy sand, having pH 8.15 0.90 dS/m electrical conductivity, 0.13% organic carbon, 130.6 kg/ha available nitrogen, 20.5 kg/ha available phosphorus and 149.6 kg/ha available potassium. The application of 25 kg N+ 50 kg P-2O5 + 40 kg K2O haand#8722;1 along with Rhizobium, VAM and PSB recorded significantly higher available nitrogen 164.1 kg haand#8722;1 and available phosphorus 26.6 kg haand#8722;1 whereas minimum were noted with the application of RDF- NPK alone. However, this treatment also provided significantly higher NPK uptake by the crop and crop yields (pod, kernel and haulm) over rest of the treatments. The minimum yields were noted with the application of alone RDF, poultry manure, vermicompost and their mixture.
