IMPORTANCE OF LEAF (CANOPY) AREA.

There should be simultaneous matching growth of storage organs of the plant at the time when the optimum photosynthesis is taking place in the matured leaves. The storage organs vary from crop to crop.
Further out of 3 to 4 gms. of dry matter (sugar) produced per day per sq. foot, distribution of sugar takes place for fruits, stem, branches, leaves, wood, pith, bark etc. For instance, out of every 3 gms. of sugar produced by a grape plant, only one gram of sugar goes for fruits, one gram for stem, branches and leaves and the remaining one gram for metabolism.
Therefore, if farmer understands this knowledge of canopy index and dry matter production through his own experimentation, his entire approach of farming changes from routine farming to scientific farming with mathematical precision.
The cellulose and lignin parts of the plants on decomposition yields humus and ligno-proteins. So returning these parts of the plants to the soil in open pits or heaps or bundles or open trenches, aerobic decomposition in situ will go on adding these components that give our soil the form and structure needed for lush, luxuriant growth of roots with well developed root mat, on which the health of plant depends.
