SUMMARY
A field experiment was conducted at research farm of Department of Agronomy, Forages and Grassland Management, CSK HPKV, Palampur during Rabi 2015-16 to assess the effect of date of sowing and nitrogen fertilization on herbage yield and nutritive value of annual rye grass. The experiment was laid out in factorial randomized block design with three replications, consisting of fifteen treatment combinations. Annual ryegrass produced significantly highest total green (662.52 q/ha) and dry (136.37 q/ha) forage yields with the application of 160 kg N/haunder sowing time of 2nd fortnight of October. Early sowing in 2nd fortnight of October as well as application of 160 kg N/ha resulted in significantly higher CPC and CPY. Also, the significantly minimum NDF content (41.76%) was recorded with the application of 160 kg N/ha. The higher values of NPK content and uptake were recorded under sowing time of 2nd fortnight of October as well as application of 160 kg N/ha. Soil properties did not affected significantly at the end of experiment except soil available nitrogen, which increased with increasing levels of nitrogen levels up to 120 kg N/ha.
