Potato (Solanum tuberosum) is a perennial plant in the family, peppers, tomatoes and tobacco normal germination time. It is based on the trunk of the branches. With a height of 50-100 cm, depending on the species. Potatoes have hollow stems and leaves are 2 types of triangular leaves with leaves. And the leaves of the flowers are white, pink, purple and dark purple flowers with 5 petals with stamens stigma 1 to 5, and the potato is part of the stem that is responsible for food and breeding. The potato crop will start to build up a head after 2-3 weeks, the skin of the potatoes with a small hole called lenticle for breathing and ventilation, so if cultivated soils are moist soil. Hole of the potatoes are large. To help breathing and circulation of water immediately. But there is a big hole in the head to make it look pretty then. Also be a way for bacteria into the head easily, so it should not be cultivated soils moist soil are also sprouting potatoes have eyes for it. The head may have a very early potatoes and 15 normal eyes, one might head to head from 6-10 depending on the fertility of the soil for planting. Potatoes are generally fast and bushy plants. If tides permitting fields would yield approximately 2 times the weight of the rice grown on the same area. Capable of durable cold and heat. Made from potatoes can be grown successfully in the height above sea level and below sea level. Farmers found the potatoes grown in the winter will yield higher than those grown in the hot weather. The potatoes will grow best at temperatures of 15-18 degrees Celsius, the temperature up to 30 ° C, the yield will be reduced. For this reason, we see that 90 percent of the potatoes from farms in Europe. In Thailand Farmers planted potatoes in winter. Is from November to January This is the time when it is raining enough. The farm is located in the most high. Tenders will be used loam or loamy sand to grow. Because the soil is well drained. And the acidity (pH) of 5.5-6.5 in terms of preparing the ground for planting. Farmers to plow the soil to a depth before. And soil for 1-2 weeks to dry land. Then the manure into the soil so that it can absorb water. Tenders may be used to grow the head. Cloth was the head If the first method, the potatoes are completely fed from the whole head. If you use the latter method Will be used to feed the little food. And sometimes fungi (Phytophthora infestans) infection may start to rot. The advantage of this method is to help farmers save money. I do not have to buy the expensive varieties. Before planting Tenders will be used to cut the head or the head, has jumped before. The eye on the top of the head sprouting from 1.5-2 cm long, to be planted. It provides a set faster. The planting depth of 5-10 cm, and then cover with soil. Then, watering, fertilizing And weeding out After 3-4 months, farmers can keep up. By observing that the mature tree trunk begins to overflow leaning against the soil and the leaves begin to turn yellow. Normally, farmers will cut the head about 7-10 days before digging in to the skin of the head, strong abrasion resistance. The potatoes should be selected to head the organization and should be carefully excavated. Do not make head wounds If not, the head is rotten disease threat. Then the potatoes air dry before you store with good ventilation and temperature is not high. Because of the low temperature will help wounds heal faster potatoes. The fungus causes no interference The sun should not interfere because if potatoes sunlight. Skin, it creates alkaloid solanine, which can cause skin with green toxic if consumed raw.
