Popis:	The effects of variety, date of cutting flush growth and level of nitrogenous manuring on the crude-protein content of Italian ryegrass were studied on plots cut five times in 1958. Raising the level of nitrogenous fertilizer from 174 lb. to 348 1b. N/acre reduced the percentage of dry matter from 0·5 to 2·0 and increased the percentage of crude protein in the dry matter from 0·9 to 5·1, with net increases in crude protein/fresh material of from 0·06 to 0·57%. Varieties showed consistent differences, the three Westcrwolth types, New Zealand H.I and New Zealand Italian being higher in percentage crude protein than Ayrshire, Irish, Danish and S22. Culling the flush growth earlier resulted in an increased percentage of crude protein for that particular cut, but no overall increase in mean crude-protein percentage.
