A field experiment was conducted at the Instructional-cum-Research (ICR) farm, Assam Agricultural University, Jorhat during 2016-2017. The experiment was laid out in split-plot design with thrice replication. The treatments consisted of three different seed rates in main plot viz., 10 kg/ha, 15 kg/ha and 20 kg/ha along with four nitrogen levels viz., 0 kg/ha, 30 kg/ha, 60 kg/ha and 90 kg/ha in sub-plots. Results revealed that seed rates and nitrogen levels effects rye grass various growth and yield parameters. A seed rate of 20 kg /ha was found to be statistically superior in regards to growth parameters in all the three cuts viz. 1st, 2nd and 3rd cut as compared to 15 kg and 10 kg seed rate/ha. The highest green forage yield (330.30 q/ha) was obtained with seed rate of 20 kg/ha and was significantly superior to 15 kg/ha and 10 kg/ha. The dry matter yield were also found to be significantly higher in seed rate of 20 kg/ha (71.88 q/ha). In case of nitrogen levels application of 90 kg N/ha resulted in higher values in almost all the growth and yield parameters. The highest green forage yield (381.43 q/ha) was also obtained in 90 kg N /ha and was significantly superior to all other lower doses of nitrogen (60kg and 30 kg N/ha).
