Rejuvenation by Top Work<strong>in</strong>g<br />
Top work<strong>in</strong>g can be easily done <strong>in</strong> rejuvenated trees to upgrade the old and senile<br />
orchards <strong>of</strong> seedl<strong>in</strong>g trees with superior commercially grown cultivars.<br />

The plants are headed back dur<strong>in</strong>g<br />
December – January to the extent <strong>of</strong> 2.5-<br />
3.0 m above the ground level. Four to six<br />
shoots from the outer directions <strong>in</strong> ma<strong>in</strong><br />
limbs should be allowed to develop.<br />
Dur<strong>in</strong>g June-July, scion <strong>of</strong> desired variety<br />
is grafted on newly emerged shoots<br />
developed on branches <strong>of</strong> pruned trees<br />
by adopt<strong>in</strong>g r<strong>in</strong>g budd<strong>in</strong>g. After sprout<strong>in</strong>g,<br />
the top portion <strong>of</strong> shoots is removed.<br />
Numerous side shoots, which emerge on<br />
pruned branches after budd<strong>in</strong>g operation,<br />
should be removed regularly as and when they emerge, so that tree <strong>of</strong> pure<br />
commercial variety is obta<strong>in</strong>ed.<br />

S<strong>in</strong>ce aonla is self <strong>in</strong>compatible, i.e. the<br />
pollen gra<strong>in</strong>s <strong>of</strong> the same tree/variety<br />
cannot fertilize its own tree / variety. The<br />
production from mono culture orchards<br />
without appropriate poll<strong>in</strong>iser varieties,<br />
suffers adversely as a result <strong>of</strong> problem<br />
<strong>of</strong> <strong>fruit</strong> sett<strong>in</strong>g. <strong>Co</strong>nsequently, poll<strong>in</strong>iser<br />
varieties are budded on develop<strong>in</strong>g shoots<br />
<strong>of</strong> pruned trees to strengthen poll<strong>in</strong>ation<br />
process and to enhance <strong>fruit</strong> sett<strong>in</strong>g and<br />
productivity.<br />
Budd<strong>in</strong>g with mixed varieties results <strong>in</strong> better yield. The best comb<strong>in</strong>ations are<br />
NA-6 with NA-7; NA-7 with NA-10 and Kanchan with Krishna. Adequate care should<br />
be taken to manage the <strong>in</strong>sect pest problems as these plants are prone to <strong>in</strong>sects<br />
and sometimes to w<strong>in</strong>d damage.<br />
