Interspecific interactions contribute to higher forage yield and are affected by phosphorus application in a fully-mixed perennial legume and grass intercropping system

Although intercropping is a common technique that has been widely applied, the effect of phosphorus (P) fertilization on productivity of a fully-mixed perennial intercropping system composed of four species, including two legumes and two grasses, has rarely been studied. The objective of this study was to determine the effect of interspecific interactions on forage yield and the influence of P application on interspecific competitiveness and...
