The simulation of the effects of shading on the growth and yield of winter barley ( Hordeum distichum)

The relationships between the amount of solar radiation intercepted by a crop canopy and the accumulation of biomass are examined in a model of the growth of winter barley. The model is used to analyse the results of a shading experiment in 1989–1990, in which 70% of the available photosynthetically...

Summary:The relationships between the amount of solar radiation intercepted by a crop canopy and the accumulation of biomass are examined in a model of the growth of winter barley. The model is used to analyse the results of a shading experiment in 1989–1990, in which 70% of the available photosynthetically active radiation is excluded from the crop during the month immediately following the expansion of the first leaf. The model confirms that photosynthetically active radiation is the main driving variable and that the crop is not able to compensate for the solar energy lost at the beginning of the growing season.
