What is the optimum temperature for potato production in Botswana?
The mean optimum temperature for tuber formation lies between 15 to 20 C. Above 32 C tuber formation and development is very poor. High soil temperatures at planting time can cause the seed to rot in the soil and lead to poor emergence. In Botswana only a few areas are suitable for potato production.
Does Botswana import vegetables from neighbouring countries?
