Soil Type
Potato prefers Well-ventilated soil with good drainage. High salinity, calcium carbonate and drought all effect negatively on both the yield and starch content.
Temperatures
The optimum temperature for grown and productivity is from 18 – 22C. Frost damage can occur if the temperature is lower than 4 C, also high temperatures effect tubers encouraging rot.
Water Requirements
Irrigation is important for all crops periods except those grown in the rainfed areas along the coast and even there some irrigation also takes place. Most farmers use furrow irrigation but there is an increasing interest in sprinkle irrigation.
Nutrition Requirements
Soil should be subject to soil analysis for nutrient availability.
Harvesting Period
Spring planted potatoes are harvested in June; summer potatoes are harvested in August; autumn planted potatoes are harvested from November to February.
Harvesting Methods
Potatoes are picked by hand following opening of the furrows by horse or tractor drawn equipment.
