Other claims from this paper (9)
- Intervention effect White clover and perennial grass mixtures yielded more forage than grass fertilized with N.
- Intervention effect Adding white clover significantly increased forage yields of perennial grasses at N rates up to 112 kg/ha.
- Intervention effect Only at 336 kg N/ha were average yields of clover/grass and grass/N comparable.
- Intervention effect Adding clover increased forage yield by 218.9% at the 0 kg/ha N rate.
- Intervention effect Adding clover increased forage yield by 93.0% at the 37 kg/ha N rate.
- Intervention effect Adding clover increased forage yield by 34.1% at the 112 kg/ha N rate.
- Intervention effect Adding clover changed forage yield by 0.2% at the 336 kg/ha N rate.
- Intervention effect Average clover/grass yields were consistently higher over the 4 years than grass/N yields.
- Recommendation White clover should be included in grass mixtures in Southern pastures to reduce the need for N fertilization.
