Effect of Nitrogen Levels and Cutting Management on Growth and Yield of Multicut Forage Sorghum [Sorghum bicolor (L.) Moench] Variety Cofs-29

A field experiment was conducted during summer season of 2014 at Anand to study the effect of nitrogen levels and cutting management on multicut forage sorghum [Sorghum bicolor (L.) Moench]. Plant height, number of tillers per metre row, leaf : stem ratio, green forage and dry matter yields was recorded with successive increase in N levels upto 120 kg ha^-1. The application of 120 kg N ha^-1 gave significantly higher growth and yield characters over 60, 80, 100 kg N ha^-1. Statistically highest green forage and dry matter yields were obtained with application of 120 kg N ha^-1. Cutting management of first cut at 60 days after sowing and 2 intervals at 50 days produced significantly higher green and dry matter yields as well as growth and yield characters. Based on the findings, nitrogen level of 120 kg N ha^-1 and cutting management of first cut at 60 days after sowing+2 subsequent cuts at 50 days interval was found to be the better combination for obtaining higher yields of sorghum under middle Gujarat conditions.
