SUMMARY
A field experiment was conducted at Udaipur during kharif 2011 to assess N doses for sorghum
genotypes. The results revealed that SSV-74 recorded maximum dry matter accumalation at 30 DAS and harvest, green as well as dry fodder yield (55.69 and 16.21 t/ha), respectively. Among nitrogen levels, application of 120 kg N/ha recorded higher dry matter accumalation at 30 DAS and harvest, HCN content at 30 DAS, green as well as dry fodder yield, net returns and B : C ratio over 40 and 80 kg N/ha. Application of 120 kg N/ha recorded 19.70, 7.89 and 20.03, 8.72 (green and dry fodder) 23.57, 9.10 and 13.93, 4.80 (net return and B : C ratio) per cent higher over 40 and 80 kg N/ha, respectively.
Key words : Nitrogen, fodder yield, quality, sorghum
