Question
Farmers in a particular region were concerned that pre-mature yellowing of leaves of a pulse crop might cause decrease in the yield. Which treatment could be most beneficial to obtain maximum seed yield?
Options
A.Frequent irrigation of the crop
B.Treatment of the plants with cytokinins alongwith a small dose of nitrogenous fertilizer a small dose of nitrogenous fertilizer
C.Removal of all yellow leaves and spraying the remaining green leaves with 2, 4, 5- trichlorophenoxy acetic acid
D.Application of iron and magnesium to promote synthesis of chlorophyll
Solution
In a pulse crop possesses premature yllowing of leaves and decrease in yield an application of magnesium and irom to promote synthesis of chlorophyll may become most beneficial to overcome the problem and to obtain maximum seed yield.
Magnesium is an importan part of ring structure of chlorophyll molecule and its deficiency causes chlorosis and premature leaf abscission.
In iron deficiency also, the leaves become chlorotic because iron is required for the synthesis of the chlorophyll protein complexes in the chloroplast.
