When tubers mature before they are harvested the skin sets. Before the skin is set the thin epidermis can easily be removed through abrasion or attrition.
This can be done manually by the grower to find out if the skin is set and the crop is ready to harvest. This to avoid skinning to take place during machine harvesting when the tubers come ungently in contact with machine parts. When the skin is peeled off, the underlying tissue is exposed and, through wound healing, will form a new skin.
Unfavorable conditions
When conditions are unfavorable for wound healing such as tuber wetting due to condensation, temperatures remote from the optimum for wound healing which is 20 °C so lower than between 14 and higher than 24 °C, tubers lose water and are susceptible to infection both reducing tuber quality. The wound, or at least the borders, however, remain visible as a defect on the tuber surface even after proper curing. Skinning is reduced when the tubers are mature and hardened when harvested.
Agritechnica focus on trends in potato technology
From 12-18 November Agritechnica takes place in Hannover, Germany. During the event there is a main focus on potatoes. Dr. Rolf Peters presents his vision on trends in potato technology. He states that potato growing has required a particularly high degree of flexibility from farmers in this year’s growing season due to the intensive change…
The efficiency of overhead irrigation for potato crops
Irrigation with sprinklers, rain guns, center pivots or linear systems – as opposed to furrow and drip irrigation delivering water under the canopy – distributes water overhead, much like natural rainfall does.
The advantages of drip irrigation in potato cultivation
Of all irrigation practices, furrow irrigation loses most water through drainage and also loses more nitrogen through leaching than other irrigation practices. Drainage through deep percolation on the other hand is an advantage as it avoids accumulation of salts at the surface. Besides, erosion is considerable as the water flow to some extent always transports…
Potato Association of America to showcase industry advances during annual meeting
The annual meeting of the Potato Association of America (PAA) is scheduled to take place from July 23rd to 27th, 2023. PAA members, potato researchers and industry partners will gather in Charlottetown, the capital of Prince Edward Island. ‘We look forward to welcoming the PAA family to Prince Edward Island for the first time since…
