Effect of plant density and water supply on wheat production.

A model is described to predict the DM production of a wheat crop. The photosynthetic rate of the crop surface is calculated from the amount of light and certain influences of the physical environment on photosynthesis, such as crop density, water supply and meteorological conditions. The dominant role of the leaf surface resistance with regard to the final yield to be reached is apparent. Lowering the sowing density at limited water supply will give favourable grain:straw ratio.
