摘要

A field experiment was conducted during 1997 and 1998 at G.B. Pant University of Agriculture and Technology, Pantnagar to study the effect of nitrogen fertilization and cutting intervals on forage yield and quality of Napier Bajra hybrid (N.B. 21) under the tarai condition of U.P. (Kumaon). Data of both the years and pooled data indicated that dry matter, crude protein, digestible dry matter yield and dry matter content increased with delay in cutting from 5 to 7 weeks interval, however, crude protein, digestibility (percent) and L:S ratio decreased with delay in cutting. Increase in nitrogen application from 0 to 150 kg/ha increased dry matter, crude protein and digestible dry matter yield and their respective contents, however, L:S ratio had negative correlation with increase in nitrogen level.
