Note générale :	A model is described to predict the dry matter 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 environnement on photosynthetis as crop density water supply and meteorological conditions. The dominante 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 a more favourable grain / traw ratio.
