Question

Farmers of a particular region are concerned that premature yellowing of leaves of pulse crop might cause decrease in the field which treatment should be beneficial to obtain maximum seed yield

Answer 1

Answer:

If a pulse crop possesses premature yellowing of leaves and decrease in yield then application of magnesium and iron to promote the synthesis of chlorophyll may become most beneficial to overcome the problem and to obtain maximum seed yield.  Magnesium is an important part of the ring structure of the chlorophyll molecule and its deficiency causes chlorosis and premature I leaf abscission. In iron deficiency also, the leaves become chlorotic because iron is required for the synthesis of some of the chlorophyll-protein complexes in the chloroplast.

So, the correct answer is 'Application of iron and magnesium to promote the synthesis of chlorophyll'.
