A field experiment was undertaken at Instructional Farm, Rajasthan College of Agriculture, Udaipur (Rajasthan) to study the effect of fertilizer levels on the productivity, quality and economics of sorghum genotypes during kharif 2006. Results showed that application of recommended dose of fertilizer (80: 40 kg N: P ha-1) gave significantly higher weight of 5 panicle, grain weight of 5 panicle, weight of 1000 grains and grain, dry fodder and biological yields, gross returns, B/ C ratio, NPK uptake over that of 50 % RDF and found at par with 150 % RDF. The corresponding increases in grain, straw and biological yields, gross returns, total NPK uptake were of the order of 7.27, 5.38, 5.82, 6.44, 31.70, 9.72 and 7.33 per cent over 50% recommended dose of fertilizers. Among elite genotypes, SPH 1467 gave significantly higher dry matter accumulation at 60 DAS and at harvest and grain yield and significantly higher NPK uptake. HC 308 recorded higher straw and biological yield, while SPV 1730 recorded higher gross returns, net returns, and B/C ratio. SPH 1467 recorded 9.17 and 167.98 percent higher grain yield over CSV 15 and HC 308.
