We have made the leaf analysis of wheat plant subjected to different fertilizer treatments by pot experiment. Cell sap concentration of leaf blade was determined by micro-cryoscopic method, but it was not clearly expressed nutritional status of plant, especially on mineral constituents. N, P, K, ca, Mg, & Fe contents of leaf blade were determined. N, K, & K contents of the leaf were good response to the deficient elements in soils, on vegetative stage, but not on the later stage of growth At early stage the results of leaf analysis of wheat plant indicated well nutritional status of plant. It is recognized that foliar diagnosis of wheat plant may be useful for forecasting the crop yield. (Sept. 1952)
