Popis:	Maximum diurnal accumulation of soluble carbohydrates in warm-season grasses is an economic way of increasing hay quality; however, in the humid East, haymaking is diffi cult. This study evaluated gamagrass (Tripsacum dactyloides L.), topdressed with either 56 (LO) or 168 (HI) kg N ha –1 , direct baled after mowing in the afternoon (PM/LO and PM/HI) or morning (AM/LO and AM/HI), wrapped with plastic fi lm, and conserved as baleage. The four baleage treatments were evaluated by steers for dry matter intake (DMI), digestibility, and N retention. Neither harvest time nor N rate altered DMI (mean = 1.87 kg 100 –1 kg body weight).
