Harvesting<br />
Highest yields are obtained by<br />
leaving potatoes in the ground<br />
until they mature. Hardening of<br />
the skin of tubers is made faster by<br />
cutting or pulling the haulm (stems<br />
and leaves) 10-14 days before<br />
harvesting of the crop. Harvest<br />
the crop using blunt objects like<br />
sticks so as to minimize damage<br />
to tubers.<br />

Harvesting, grading,<br />
storage and marketing<br />
greened and damaged tubers before<br />
packing potatoes for sale or storage.<br />
Potatoes can be graded by sizes into<br />
baby potatoes (less than 30 mm),<br />
small (30-45 mm), medium (45-65<br />
mm) and large (65-80 mm). Keep<br />
tubers for eating in dark stores to<br />
prevent greening. The store should<br />
be cool with enough circulation of<br />
air.<br />
Marketing<br />
Marketing of potatoes is<br />
generally the responsibility of the<br />
grower and is characterized by a<br />
strong presence of brokers. Farmers<br />
may enter into contracts to supply<br />
processors with desired potato<br />
varieties. according to legal notice<br />
no. 44 of 2005, ware potatoes for<br />
trade should sorted and graded<br />
and only be packaged in sisal or jute<br />
bags. The size of such a bag should<br />
be enough to accommodate ware<br />
potato of 110 kg. The legal notice<br />
no. 113 of 2008, empowers local<br />
authorities to enforce the regulations<br />
on ware potato packaging.
