When potato originally was introduced from South America to Europe and from there was distributed globally, hardly any diseases and pests came.

The development rate of pests and disease is the increase rate of their population.

The seed tuber as propagation material of the potato plant is determined by, amongst other things, its size and age.

Like insects, potatoes have four distinct appearances.

Seed tubers (seed potatoes) within and between lots differ in health status.

Yield gap analysis (YGA) consists of obtaining and processing data on potential, attainable and actual yields.

The climatic factor that most affects yields in rainfed crops is precipitation, mainly as rain during the growing season.

Where rainfall is intensive, leading to a risk of flooding and erosion, and when all operations from tillage through harvest are manual, using.
