Description Equations are derived to predict the duration of three growth stages of sorghum under adequate moisture and nutrient availability, on the basis of temperature and relative humidity, following an iterative regression approach. The predictions are very good. The response of temperature on phenophase duration was curvilinear. The common base temperature of 10°C and the point of inflection temperature of 19.6°C are shared by all the 4 genotypes studied, but the degree of response in development by each of them varied considerably. The response for each growth stage was different. This study also presents a simple iterative regression approach to solve non-linear functions. This procedure is very valuable where facilities such as sophisticated computers or programmable calculators are lacking.
