Name two varieties of maincrop potatoes - Leaving Cert Agricultural Science - Question a - 2019

Soil preparation for maincrop potatoes involves ploughing or digging the soil to a depth of around 15-20cm. This process removes stones and other debris, creating a fine, well-aerated seedbed. Rotating or harrowing the soil is also recommended to achieve an even texture.

Maincrop potatoes are typically planted between March and April. This timing allows the plants to take advantage of the warming soil temperatures which promote better growth.

Weed control can be managed by applying herbicides, either in a chemical form or mechanical methods such as hand-pulling. Crop rotation can also help reduce weed pressure, along with shading techniques or earthing up the potatoes to prevent weed growth.

The harvesting of maincrop potatoes can be performed using a potato harvester or elevator digger. Manual harvesting is also an option, engaging workers to carefully gather the potatoes once they are mature.

The expected yield for maincrop potatoes ranges between 30 to 40 tonnes per hectare, depending on the variety and cultivation practices employed.

After harvesting, maincrop potatoes should be stored in a cool environment to prolong their shelf life. Ideal storage conditions include a well-ventilated shed or a refrigerated area, ensuring that the potatoes are kept free from light and high humidity.
