Canopy Management <strong>in</strong> Fruit Crops<br />

Passion <strong>fruit</strong><br />

S<strong>in</strong>ce passion <strong>fruit</strong> v<strong>in</strong>e bears <strong>fruit</strong>s<br />

only on current season’s growth,<br />

systematic prun<strong>in</strong>g encourages new<br />

growth. Prun<strong>in</strong>g should be done after<br />

harvest<strong>in</strong>g <strong>in</strong> April and November-<br />

December.<br />

It is done by cutt<strong>in</strong>g back <strong>of</strong> laterals to<br />

the nearest active bud as, otherwise<br />

with <strong>in</strong>crease <strong>in</strong> age <strong>of</strong> the lateral,<br />

the basal buds become dormant or<br />

sterile.<br />

Indiscrim<strong>in</strong>ate and drastic prun<strong>in</strong>g <strong>of</strong> <strong>in</strong>active or dormant v<strong>in</strong>e may lead to a<br />

setback <strong>in</strong> growth, result<strong>in</strong>g <strong>in</strong> lower yield.<br />

Skilful trellis<strong>in</strong>g is quite important <strong>in</strong> regulat<strong>in</strong>g yield as it has to support a<br />

considerable weight for 5 years. Weak and faulty construction <strong>of</strong> trellis result <strong>in</strong><br />

sagg<strong>in</strong>g and loss <strong>of</strong> v<strong>in</strong>es. Two arm kniff<strong>in</strong> system is ideal.<br />

The trellis should always run across the slope or <strong>in</strong> north-south direction to facilitate<br />

even exposure to the sunlight. Once the v<strong>in</strong>es reach the wire, the tips are p<strong>in</strong>ched<br />

to facilitate leader formation.<br />

Two leaders are directed on either side <strong>of</strong> the wire <strong>in</strong> opposite direction which <strong>in</strong><br />

turn develop laterals. These laterals are tra<strong>in</strong>ed downwards hang<strong>in</strong>g from the wire<br />

and form the <strong>fruit</strong><strong>in</strong>g area <strong>of</strong> the v<strong>in</strong>e.<br />
