Leaf Colour
Results of assessment of leaf chlorosis are summarized in Table 3. Data did not
show significant interactions, and so only the average values for the main factors are
listed. For tomato no significant differences for leaf colour were found. For cucumber a
decrease in chlorosis was evident with addition of high Fe in comparison to the standard
application. With Mn no real differences were found and high Zn additions increased
yellowing of the leaves.
