Abstract The objective was to develop a practical method of measurement of crop moisture status which could be used in the field and to interpret the measurements thereby obtained in terms of irrigation need. A small inexpensive pressure chamber was developed, tested, and shown to give reasonable accurate values for the moisture status of corn and soybeans. Laboratory simulation studies of corn and soybeans showed that during vegetative development leaf enlargement was more sensitive to drought than photosynthesis and dark respiration. These parameters were correlated with pressure chamber measurements. It was therefore concluded that irrigation needs could be based on the maintenance of leaf enlargement alone. (Author)
