Radiation interception and radiation use efficiency of wheat and pea under different P availabilities

Above-ground biomass of crops can be expressed as the product between the cumulative intercepted radiation by the crop canopy (IR) and the radiation use efficiency (RUE) of the crop. The aim of the present study was to comparatively evaluate in wheat and pea these ecophysiological determinants of biomass under different P supplies at field conditions. Two field experiments were conducted in southern Chile combining two crops (wheat and pea) and...
