SUMMARY

A field experiment was conducted at Centre for Millets Research, SDAU, Deesa during kharif-2018 with four single cut forage sorghum genotypes (CSV 21F, CSV 30F, SPV 2445 and SPV
2316) grown at three fertility levels {75% recommended dose of fertilizer (RDF), 100% RDF (80 kg N
+ 40 kg P2O5 ha-1) and 125% RDF}. Results showed that application of 75% RDF markedly increased growth parameter plant height while 100 % RDF markedly increased yield attributes like stem
diameter, green and dry fodder yields, fodder productivity and profit in single cut forage sorghum. Genotype SPV 2316 was promising as single cut forage sorghum under rain-fed environment of Northern Gujarat as it performed well in terms of growth, yields and productivity with higher remuneration than other genotypes.
