SUMMARY

A field experiment was conducted at main Forage Research Area, CCSHAU, Hisar with three multicut genotypes of sorghum (SPH 1626, SPH 1627 and CSH 20MF) were grown with four fertility levels viz., control, 50 per cent recommended dose of fertilizer (RDF), 100 per cent RDF (100 kg N+30 kg P2O5/ha) and 150 per cent RDF. The plant height, green fodder and dry matter yield of
multicut sorghum genotypes were significantly influenced by different fertility levels. The green fodder and dry matter yield of CSH 20 MF were significantly higher over SPH 1626 and SPH 1627 on the basis of total of two cuts. The maximum plant height, number of tillers, green fodder and dry
matter yield were recorded at 150 per cent of recommended dose of fertilizer (RDF), which was significantly higher than lower doses of fertilizer during both the cuts. The highest crude protein yield and digestible dry matter (DDM) were also recorded with 150 per cent RDF which were significantly higher than lower fertility levels.
