WHAT IS THE REQUIRED STORAGE OF TABLE POTATOES AFTER HARVESTING?

by | Aug 30, 2020 | Blog, Uncategorized

Once the potatoes have been harvested, it’s not the end of the story. Storage is very important.

-Seed potatoes are stored at low temperatures in cold rooms, to minimize decay and to control the physiological age of the tubers.

-Fresh market potatoes are kept at low temperatures to minimise weight loss and maintain a fresh, good-looking tuber.

-French fry and chipping potatoes need to be stored at higher / warmer temperatures, to minimise the level of reducing sugars. Reducing sugars accumulate above 25˚C and the changes induced by higher temperatures are irreversible.

Growers can also influence potato storage and cooking quality by :

– Selecting the right variety with the right cooking quality for their market.

– Irrigation scheduling to maximise quality characteristics.

– Minimising damage during harvesting.

-Using storage treatments (e.g. pesticides) to reduce tuber disease build-up.

-Controlling temperatures in storage

POTATO FARMING GUIDES

Guide1: Selecting and Handling Potato Seed

Generally, a “five percent rule” applies with seed lots. A seed lot with five percent or more total defects is too high to use. To determine the physiological age of seed potatoes, gather a sample, place them indoors and allow them to sprout. Observe the sprouts that...

The growth of a potato can be broken down into five stages.   The table above has been reproduced with permission from Johnson, D. A., ed., 2008, Potato Health Management, 2nd ed., American Phytopathological Society, St. Paul, MN. Growth Stage I: Sprout...
