Effect of INM on Soil Nutrient and Yield in Groundnut Field of Semi-Arid Area of Rajasthan.

A field experiment was conducted during kharif 2006 at farmer's field, Ghatolia (Kalakh), Jobner. The soil was loamy sand, having p^H 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 ha⁻¹ along with Rhizobium, VAM and PSB recorded significantly higher available nitrogen 164.1 kg ha⁻¹ and available phosphorus 26.6 kg ha⁻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.
