Notes:
Summary The Claassen and Barber mechanistic mathematical model was used to predict P uptake by two tomato (Lycopersicon esculentum Mill.) cultivars, C-37 and Knox. The model was evaluated by comparing observed P uptake by tomato plants growing 13, 16, 19, and 22 days under sufficient and insufficient soil P conditions with predicted P uptake. Root morphological and physiological characteristics and soil P-supply parameters were combined, in the model, to predict P uptake. There was a high correlation (r=0.97 and r=0.99) between predicted and observed P uptake by tomato plants grown at both soil-P levels. However, at the insufficient level the model underpredicted uptake.
