During the 1975-78 period pot experiments were established and nitrate reductase activity was determined in leaves of tomato and corn plants. The results obtained indicate that nitrate reductase activity assay in leaves has no advantage over total nitrogen determination in them. The relationships obtained showed that nitrate reductase activity in comparison to total nitrogen determination in some cases meet but to a lower degree and in others not the basic principles of conventional leaf analysis. For the time being nitrate reductase activity cannot be used in1220stead of total nitrogen determination as an improved diagnostic tool for the appraisal of nitrogen requirements of c
