If you are a potato plant then a sweltering summer can be too much of a good thing. New studies show a clear correlation between increasing temperature and decreasing yield.

It might be true that climate change can heat up the Danish summer and transform Denmark into the tourist paradise of the future. However, if you prefer a steady supply of Danish-grown potatoes on your dinner table, you should be asking for cool summers.

Warming of the Danish summer weather is not exactly good news for potato farmers. New studies indicate that the optimal temperature in the potato growing season is around 15° C [59F] and that for each 1° C [1.8F] increase in temperature the dry matter yield falls by 10 percent. Temperature is even more important than the level of nitrogen fertilisation.
