An experiment was conducted at Anand during rainy (kharif) season of 2004 and 2005 to study the effect of in- tegrated N management on yield and quality of multi-cut forage sorghum (Sorghum sudanense L.). Application of 75 kg N through urea + 25 kg Nlha through farmyard manure (FYM) recorded significantly higher green-forage, dry-matter and crude-protein yields than other treatments, except application of 75 kg N through urea + 25 kg Nlha through castor cake. The increase was 11 .I - 18.6% in dry-matter yield and 19.4 - 20.0% in crude-protein yield over application of 100 kg Nlha through urea. Application of 50 kg N through FYM + 50 kg Nlha through castor cake was significantly inferior in forage production and was poor in quality as evident from low crude-protein yield and higher neutral detergent fibre (NDF) content. The maximum green-forage, dry-matter and crude-protein yields of forage sorghum were recorded under Azotobacter + Azospirillum inoculation compared with their individual in- oculation or no inoculation of biofertilizer, but the effect on green-forage yield was non-significant.. The maximum NDF content was recorded under no biofertilizer treatment, which was significantly higker than other treatments except Azospirillum inoculation. The application of 75 kg N through urea + 25 kg Nlha through castor cake along with Azospirillum inoculation was found superior in forage quality and recorded maximum crude-protein yield.References
