Growth performance and weed control effect in response to nitrogen supply for switchgrass after establishment in the semiarid environment

Switchgrass (Panicum virgatum L.) adapts to a wide range of environments. It has been successfully planted in a semiarid region of China’s Loess Plateau as a valuable forage species for restoring vegetation of grassland. However, growth performance of switchgrass needs to be further evaluated after establishment. Relationships between switchgrass growth and outcomes of weed control in terms of nitrogen (N) supply are especially not well...
