SUMMARY

A field experiment was carried out at the Instructional-cum-Research Farm of Assam Agricultural University, Jorhat during Rabi, 2016-2017 to study the effect of different levels of nitrogen and time of application on ryegrass (Lolium multiflorum) for higher fodder production. Results revealed that application of 90 kg Nitrogen/ha in three splits as 40% basal + 30% after first cut + 30% after second cut produced the highest fodder yields with economic returns. The increase in total green fodder yield due to application of 30, 60 and 90 kg Nitrogen/ha over 0 kg Nitrogen/ha was 50.5, 59.0 and 64.8 per cent, respectively. The corresponding increase in total dry matter yield was 24.7, 33.0 and 38.3 per cent.
