Abstract

The most important climatic factor influencing potato cultivation is temperature. The minimum temperatures determine the possible planting time and thus the growing period, while the maximum temperatures can have a negative impact on vegetative and tuber growth. The optimum air temperatures for the vegetative growth of potatoes are between 20 and 25 °C, while the optimum soil temperatures for tuber growth are between 15 and 20 °C. Depending on the climate, potatoes require between 500 and 700 mm of precipitation during the growing season. In recent years, there have been strong fluctuations in both the amount and intensity of precipitation, which increases the risk of the root system drying out or oxygen deficiency if there is a high amount of precipitation in a short period of time. Comparing the biological requirements of the potato with the climatic data, it can be concluded that potato cultivation in the Republic of Croatia is possible almost all year round if planted in the appropriate growing seasons. The risk of damage due to low temperatures can be reduced by planting in low or high tunnels or by covering directly with agrotextile immediately after planting. In the summer months, an even water supply must be ensured by means of an irrigation system.
