Abstract: A field experiment was conducted during kharif season of 2016 at Agronomy Instructional Farm, C. P. College of Agriculture, S. D. Agricultural University, Sardarkrushinagar, Gujarat to study integrated nutrient management on green forage yield, quality and nutrient uptake of fodder sorghum. The experiment consist of 16 treatment combinations of 4 organic manures, viz., 10.0 t FYM/ha, 15.0 t FYM/ha, 1.0 t castor cake/ha and 2.0 t castor cake/ha and 4 fertility levels, viz., Azotobacter + PSB (Control), 50 % RDF + Azotobacter + PSB, 75 % RDF + Azotobacter + PSB and 100 % RDF + Azotobacter + PSB. The use of castor cake @ 2.0 t/ha resulted in significantly higher green and dry fodder yield being at par with 15.0 tonnes FYM/ha as compared to its lower levels. Significantly higher leaf area per plant, stem diameter, number of internodes per plant, length of internode and leaf stem ratio were recorded with the application of 2.0 t castor cake/ha. Similarly, 100% RDF along with Azotobacter + PSB significantly improved all growth and yield attributes as compared to 50 % RDF + Azotobacter + PSB and control. Application of castor cake 2.0 t/ha recorded significantly the highest protein content, NPK uptake and available nutrients in the soil (N & P), whereas it registered the lowest crude fibre content. Use of 100% RDF along with seed inoculation of Azotobacter + PSB also rewarded significantly highest protein content, NP uptake and post harvest soil available nutrients (N & P) as compared to lower levels and control. However, it also rewarded significantly lower crude fibre content in the fodder.
