'Dodoma Edible' outyielded 'Natal Common' groundnut due to varietal effects associated with differences in pod number, leaf area duration, crop growth rate, number of grains per pod and square meter, and weight of individual grain. Increase in plant density led to an increase in grain yield. There was a close and positive relation between stem and pod dry weight; grain yield and leaf area duration; and crop growth rate, grain yield and grain number per square meter of land surface. A greater proportion of total dry matter was diverted into the stems of 'Dodoma Edible' than 'Natal Common'.
