Other claims from this paper (17)

Intervention effect Crabgrass percentage was low in 1990 and unresponsive to cutting height.
Association In 1991 crabgrass percentage rose with cutting height.
Association In 1991 crabgrass percentage fell with cutting interval.
Association Dry matter yield fell linearly with greater cutting height.
Association Dry matter yield rose linearly with longer cutting interval.
Association Crude protein percentage fell with longer cutting interval.
Association Crude protein response to height changed from negative to positive as interval increased.
Association Digestibility rose curvilinearly with cutting height.
Association In 1991 IVOMD declined curvilinearly with longer cutting intervals.
Observation Highest DM yield occurred with six-week interval and one-inch height.
Observation That high-yield treatment gave the lowest protein and digestibility.
Observation Highest forage quality occurred at one-week cutting intervals.
Association At each interval, protein and digestibility tended to be higher at seven-inch height.
Recommendation Raising cutting height to four inches may improve hay quality.
