ABSTRACT
The efficiency of the Shardakov or dye mothod in measuring the leaf water potentials of cassava (Manihot esculent Crantz var. Hawaiian 4) and soybean (Glycine max [L.] Merr. var. Clark 63) was evaluated and compared with that of the pressure chamber measurements were made on whole leaves while Shardakov method measurements were made on leaf discs. A regression analysis showed an agreement between the two methods. Results indicate the Shardakov or dye method is as useful as the pressure chamber apparatus in measuring the left water potentials of cassava and soybean.
