- Intervention effect Nitrogen fertilization promoted a quadratic response of dry matter yield in Cenchrus purpureus, with an estimated maximum at 89.15 kg N ha−1.
- Intervention effect Nitrogen levels produced quadratic patterns in structural traits of Cenchrus purpureus, indicating optimized development at intermediate nitrogen.
- Intervention effect Nitrogen levels produced quadratic patterns in in vitro digestibility of Cenchrus purpureus.
- Intervention effect Nitrogen fertilization increased crude protein linearly in Cenchrus purpureus.
- Intervention effect Nitrogen fertilization produced nonlinear responses in fiber fractions and nonfiber carbohydrates of Cenchrus purpureus.
- Intervention effect Nitrogen supply produced a quadratic response of gas losses in silage of Cenchrus purpureus.
- Intervention effect Nitrogen supply produced a quadratic response of silage pH in Cenchrus purpureus.
- Intervention effect Nitrogen supply linearly decreased effluent losses from Cenchrus purpureus silage.
- Intervention effect Nitrogen supply linearly increased DMR of Cenchrus purpureus silage.
- Intervention effect Nitrogen fertilization decreased fiber fractions of Cenchrus purpureus.
