Abstract:
A field experiment was conducted on clay loam soil at Instructional Farm, Rajasthan College of Agriculture, Udaipur during two consecutive kharif season of 2014 & 2015 and rabi seasons of 2014-15 & 2015-16. The objectives were to assess effect of fertility levels, biofertilizer and organic manure on yield of fodder sorghum and to evaluate the residual effect of these on succeeding barley crop. Application of 100 % RDF to fodder sorghum registered highest N, P, K uptake by dry fodder which was significantly higher over lower fertility levels. The magnitude of increases in N, P and K uptake was to the tune of 11.1, 13.5, 8.3 per cent over 75 % RDF and 27.7, 29.3, 18.8 per cent over 50 % RDF, respectively. The crop inoculated with Azotobacter + PSB accumulated higher quantum of N, P and K by dry fodder as compared to inoculation of PSB and Azotobacter alone. Application of vermicompost to sorghum registered highest N,P,K and its uptake by dry fodder over no manure. Crop under residual effect of 100% RDF also accumulated highest quantum N, P and K in dry fodder. The barley crop accumulated highest quantum of N, P and K in dry fodder.
