necessary in older plantations,
where canopies are overcrowded
resulting in reduction in yield.
This is possible by heading back
exhausted canopy at 1.0 - 1.50
m height from the ground level.
Immediately after heading back,
pruned wood needs to be removed
from the plant so as to prevent the
damage by shoot borer.
Remaining portion of the trunk and
exposed part of roots is to be swabbed with 0.2 % chlorpyriphos at least 2-3
times after beheading till new canopy is developed. Regular checking for damage
by cashew stem and root borer is to be done and managed.
The cut ends of branches should be smeared with 10% Bordeaux paste to prevent
the gummosis and entry of any pathogens. The best season for heading back is
May-June, i.e. immediately after harvesting of annual crop.

Senile tree develops into a

The new flushes arise from the
dormant buds on the trunk. These
new sprouts form the canopy within
a period of 6-7 months depending
on the variety.
The yield during the first season
after pruning is slightly lower, while
from second season onwards it is
better than the unpruned plants.
Good phytosanitary procedures
should be adopted to manage the
rejuvenated plants.
