and muriate <strong>of</strong> potash needs to be applied dur<strong>in</strong>g February end. After that, light<br />
irrigation is required.<br />
The rema<strong>in</strong><strong>in</strong>g half dose <strong>of</strong> urea is applied dur<strong>in</strong>g June end.<br />
Manures and fertilizers should be applied <strong>in</strong> the bas<strong>in</strong>s prepared around trees, leav<strong>in</strong>g<br />
about 1.5 m radius around the base <strong>of</strong> tree trunk. The fertilizer should be mixed<br />
thoroughly <strong>in</strong> soil up to the depth <strong>of</strong> about 15-20 cm.<br />
Full dose <strong>of</strong> well decomposed FYM (120 kg/ tree) should be applied dur<strong>in</strong>g first week<br />

Bas<strong>in</strong> irrigation is followed at an <strong>in</strong>terval <strong>of</strong><br />
15 days from April to onset <strong>of</strong> monsoon.<br />
Pr<strong>of</strong>use emergence <strong>of</strong> new shoots starts<br />
April onwards on pruned branches which<br />
requires th<strong>in</strong>n<strong>in</strong>g <strong>of</strong> excessive shoots.<br />
About 8-10 healthy shoots with outwardly<br />
growth are reta<strong>in</strong>ed per branch and<br />
rema<strong>in</strong><strong>in</strong>g shoots are removed. Th<strong>in</strong>n<strong>in</strong>g<br />
operation is followed <strong>in</strong> June and if<br />
required, <strong>in</strong> August. Spray<strong>in</strong>g <strong>of</strong> copper<br />
oxychloride (3g/litre <strong>of</strong> water) should be<br />
done after th<strong>in</strong>n<strong>in</strong>g.<br />
Proper <strong>in</strong>spection is needed for <strong>management</strong> <strong>of</strong> stem borer <strong>in</strong>sect. If there is<br />
any symptom <strong>of</strong> stem borer <strong>in</strong> the form <strong>of</strong> wooden frass on any tree / branch, its<br />
<strong>management</strong> is required immediately.<br />
Grub/larvae <strong>of</strong> <strong>in</strong>sect can be pulled out from the hole by us<strong>in</strong>g a th<strong>in</strong> wire or cycle<br />
spoke. They can be traced from hole hav<strong>in</strong>g wooden dust accumulated on adjo<strong>in</strong><strong>in</strong>g<br />
bark and gum ooz<strong>in</strong>g spots along the tunnel made by them <strong>in</strong> branches.<br />
<strong>Co</strong>tton swab, soaked with Nuvan (hav<strong>in</strong>g fumigant action) <strong>in</strong>secticide, could also be<br />
<strong>in</strong>serted <strong>in</strong> holes to effectively elim<strong>in</strong>ate and control the grub/larvae <strong>in</strong> the tunnel itself.<br />
After plac<strong>in</strong>g the swab, the hole might be plastered with mud so that the fumes <strong>of</strong><br />
<strong>in</strong>secticide could not escape.<br />
Leaf cutt<strong>in</strong>g weevil affects new shoots, especially dur<strong>in</strong>g monsoon season. It
