SUMMARY
A field experiment was conducted at main Forage Research Area, CCSHAU, Hisar during kharif 2011 with four single cut sweet sorghum genotypes (SSV 84, SSV 75, CSV 19 SS and HC 308) and two nitrogen levels (80 and 120 kg N/ha). The plant height, number of tillers per metre row length, green fodder and dry matter yield of sweet sorghum genotypes were significantly influenced by different fertility levels. The highest green fodder yield (428.8 q/ha) and dry matter yield (111.8 q/ha) were recorded in genotype CSV 19 SS followed by genotype HC 308. The maximum plant height, number of tillers, green fodder and dry matter yield were recorded at 120 kg N/ha, which were significantly higher than lower dose i. e. 80 kg N/ha.
