SUMMARY
A field experiment was conducted during zaid season of 2013 at Udaipur, Rajasthan on clay loam soil to assess the effect of fertility levels on muti-cut genotypes of forage sorghum. Among multi-cut forage genotypes, SPH 1697 proved most efficient as it gave significantly higher green (72.54 t/ha), dry (21.02 t/ha) fodder yield on the basis of total of three cuts, net monetary returns of Rs. 58832/ha and B : C ratio of 3.11 with lesser HCN content. The crop fertilized with 100 per cent RDF recorded significantly higher green and dry fodder yield on the basis of total of three cuts over control, application of 50 and 75 per cent RDF. The magnitudes of increases were 67.1, 39.9 and 12.5 per cent in green fodder, and 64.6, 32.5 and 9.3 per cent in dry fodder yield, respectively. Application of 100 per cent RDF also fetched highest net returns (Rs. 59445/ha) and B : C ratio (2.93) as compared to lower fertility levels.
Key words:Multi-cut sorghum genotypes, fertility levels, fodder yield, net returns
