Potato Growing




Climate;


- The potato has a wide range of seasonal adaptabilitiy.


- It is a cool season crop and is moderately frost tolerant.


- Temperature during the growing season has long been recognized as one of the most important factors influencing yield.


- Young plants grow best at a temperature of 24degree; later growth is favored at 18 degree. Tuber production reaches a maximum at 20degree; decreases with rise in temperature, and at about  30degree tuber production stops entirely.


- Short days are beneficial for tuber production.


Soil;

- The potato develops best on deep, fertile, sandy to clay loams with good water retention capacity.


- The potato has a relatively weak, shallow root system, impermeable layers in the soil limit rooting depth which restricts water availability to the plant in dry periods.


- Soil compaction can greatly reduce potato yields.


- Aeration of the soil has a great effect on the set and development of tubers.


Manures and Fertilizers;


- N,P,K can be applied after the soil analysis is done. Excess application can be inhibit the absorption of some others elements.


- Organic manure or green manure can be recommended according to potato varieties.


Seed Rate;


- Potatoes are propagated by tubers, planted whole tubers to obtain maximum yields, healthy, disease-free tubers, free from mixture of other varieties, should be use.


- Seed rate depends on tuber size and varieties.


Irrigation;


- Potatoes need frequent irrigation.


- The first irrigation should be given immediately after sowing, and thereafter at one week intervals.


- After tuber formation, the frequency of irrigation is decreased.


- Irrigation should be stopped a few days before harvesting.
