The expolinear equation for crop growth (Goudriaan and Monteith, Annals of Botany 66: 695-701, 1990; Goudriaan, 1994. In: Monteith JL, Scott RK, Unsworth MH, eds. Resource capture by clops. Nottingham: Nottingham University Press, 99-110) has the potential to predict growth under specified environmental conditions. The choice of suitable parameters is discussed and tested using data from field experiments with faba bean, peas and lentils (Ishag and Dennett, Annals of Botany 82: 497-505. 1998). It is suggested that suitable parameters for predicting crop growth are the fraction of solar radiation intercepted at emergence, the extinction coefficient for solar radiation, the maximum fraction of radiation intercepted, the maximum relative growth rate and the maximum crop growth rate for a crop intercepting all the incident radiation. In the experiments considered, the differences in growth patterns were due mainly to differences in the maximum relative growth rare associated with differences in temperature.
