be done <strong>in</strong> such a manner as to reta<strong>in</strong> four well<br />

distributed shoots <strong>in</strong> all directions. These shoots<br />

develop as primary branches<br />

If crotch angle <strong>of</strong> reta<strong>in</strong>ed shoots is smaller,<br />

then bend<strong>in</strong>g should be done at this stage to<br />

<strong>in</strong>crease the crotch angle <strong>of</strong> newly developed<br />

shoots. It should be done with a jute rope (use<br />

<strong>of</strong> nylon or poly threads should be avoided).<br />

Second cutt<strong>in</strong>g is required when these shoots<br />

atta<strong>in</strong> maturity. Shoot maturity <strong>in</strong> mango is<br />

determ<strong>in</strong>ed by colour change <strong>of</strong> shoots from<br />

green to brown. Generally, this stage comes after<br />

7-8 months <strong>of</strong> shoot growth <strong>in</strong> north India.<br />

Thus, second cutt<strong>in</strong>g <strong>of</strong> primary branches is done <strong>in</strong> October-November. This cutt<strong>in</strong>g also<br />

<strong>in</strong>duces new growth dur<strong>in</strong>g ensu<strong>in</strong>g spr<strong>in</strong>g season.<br />

Aga<strong>in</strong>, th<strong>in</strong>n<strong>in</strong>g <strong>of</strong> excessive shoots should be done to ensure 2-3 shoots per primary branch.<br />

These shoots develop as secondary branches.<br />

This <strong>in</strong>itial tra<strong>in</strong><strong>in</strong>g results <strong>in</strong> open and spread<strong>in</strong>g <strong>canopy</strong> <strong>of</strong> trees.<br />

Shoot <strong>management</strong> for better <strong>canopy</strong><br />

In bear<strong>in</strong>g mango trees, for <strong>management</strong><br />

<strong>of</strong> <strong>canopy</strong> and enhanc<strong>in</strong>g their<br />

productivity, identify uprightly grow<strong>in</strong>g<br />

branches <strong>in</strong> each tree and th<strong>in</strong> them out<br />

for <strong>in</strong>creas<strong>in</strong>g the productivity.<br />

Remove only one or two uprightly grow<strong>in</strong>g<br />

branches from centre <strong>of</strong> tree to reduce<br />

tree height significantly and <strong>in</strong>crease<br />

availability <strong>of</strong> light <strong>in</strong>side the <strong>canopy</strong> for<br />

better photosynthesis.<br />

Cutt<strong>in</strong>g <strong>of</strong> uprightly grow<strong>in</strong>g branches<br />

should be done dur<strong>in</strong>g October -<br />

December from the base <strong>of</strong> their orig<strong>in</strong>.
