SUMMARY
A field experiment was conducted during kharif season of 2015 at Udaipur, Rajasthan on sandy clay loam soil to assess the effect of fertility levels on multicut genotypes of forage sorghum. Among multicut forage genotypes, CoFS-29 proved most efficient as it gave significantly higher green (74.78 t/ha), dry (23.77 t/ha) fodder yield on the basis of the total of two cuts, net monetary returns of Rs. 66430/ha and B : C ratio 2.15. The crop fertilized with 125 per cent RDF recorded significantly higher green and the dry fodder yield on the basis of the total of two cuts over application of 50, 75 and 100 per cent RDF. The magnitudes of the increases were 35.52, 19.82 and 8.82 per cent in total green fodder, and 45.13, 18.90 and 9.63 per cent in total dry fodder yield, respectively. Application of 125 per cent RDF also fetched highest net returns (Rs. 71814/ha) as well as the maximum B : C ratio (2.23) as compared to lower fertility levels.
Key words: Fertility levels, fodder yield, multicut sorghum genotypes, net returns
