The field experiment was conducted during Kharif season of 2010-11 at Instructional Dairy farm, G B pant University of Agriculture & Technology, Pantnagar to study the effect of seed rates and nitrogen levels on green fodder yield and quality of teosinte (Euchlaena mexicana Schrad) yield of teosinte. The growth and yield attributes, green and dry fodder yield, digestible dry matter, crude protein and nitrogen uptake increased with both seed rates and N levels. The green fodder yield was found signficantly higher at 50kg seed rate/ha that 16.8% higher yield than 40kg sed rates/ha. The same trend was also found in dry matter with highest value at 50kg seed rate with 14.5% more dry matter yield than 40kg seed rate/ha. Similarly, the green and dry fodder yield were recorded signficantly highest at 150kg N/ ha which gave 14.5 and 18.6% higher green and dry foder yield , respectively than 100kg N/ha. The crude protein and nitrogen uptake were also found higher at 50 kg seed rate and 150 kg N/ha. It is therefore concluded that 50 kg seed rate with 150 kg N/ha is required for production of high quality green and dry fooder yield of teosinte in Tarai region of India.
