Sweet potato, including seasonal crops. This plant is suitable for planting in the area with an altitude of 500 s / s 1000-above sea level and temperature of 21-27 degrees Celsius and receive 10 hours of sunlight per day.
humidity (RH) 50% - 60% with 750 mm of rainfall, 1500 mm per year. Sweet potatoes planted in the sandy loam ideal, friable, many containing organic materials with a pH of 5.5 to 7.
Sweet potato plant was formed at the age of 3 weeks after planting. Varieties of potatoes sweet about Mendut, Kalasan, lampeneng, sapodilla, Cilembu, Rambo, papaya, piles, klenang, Georgia, Borobudur, and others. The variety is said to excel when yield of at least 30 tonnes per hectare and short duration of 3 to 4 months old.
Sweet potatoes can be propagated vegetatively using stem cuttings or leaves. Leaf cuttings material used must meet the requirements of the plant material at least 2 months or more, the growth of plants that will be taken hunger seteknya in the state healthy and normal and not very fertile, has experienced a period of storage in the dark for 1-7 days.
Sweet potatoes will be planted should be prepared enough land. Land preparation is when the soil is not too wet or too dry for its structure is not broken, sticky or hard. Land preparation is done by treating soil to lose guludan-guludan once made, which later 1minggu. Guludan can be mulched.
Sweet potatoes are planted dilahan dry penanman the best time is during the rainy season at the beginning or the beginning of the dry season when the weather is normal. When planted rice dilahan proper planting time is in early dry season. cropping systems of sweet potato can be done monokulture or intermediaries.
Sweet potato, although resistant to drought, but in the early phase of growth requires adequate water. Stitching is done after 3 weeks old plants and fertilization occurs at the time of planting and the plants after 45 days. Pembubunan weeding and implemented when the plant reaches the age of 1 month after planting that is repeated when the plants are 2 months.
Sweet potatoes are harvested in a timely manner will result in tuber quality and high production yield. Harvest is too slow or too fast is bad for the quality produced. The latest crop of a lowering blood sugar levels also cause the risk of pest attack Bolenge
harvest period for sweet potatoes is influenced by various factors such as climate, the level of soil fertility, varieties and planting sites. If planted didataran higher than the harvest will be more time between 5-6 months, whereas when planted in the plains can be harvested at the age of 3 to 4 months
Sweet potato yields vary widely depending on the location of the plantation. Lowland planting sweet potatoes can be harvested up to 15-20 tons / hectare. For the Plains be able to sweet potato harvest 20-25 tonnes / ha and high didataran can be harvested 25-30 tons / hectare.
Sweet potatoes can be stored up to 5-6 months depending on how more storage. The sweet potatoes that were stored taste sweeter than sweet potatoes just harvested. The most convenient way for sustainable integrated is stored in the sand.
SWEET POTATO improving production ENGINEERING
The role of commodity tubers (cassava, sweet potato). In general as a source of carbohydrate foods, animal feed and industrial raw materials and processed food. In the future, the role of increasingly important strategic and in line with the development of processing technologies, among others, namely cassava as feedstock for chemical production of glucose, fructose, monosaccharides and and other raw materials for bioethanol, while for the sweet potato with the content of beta-carotene (provitamin A) and anthocyanins (antioxidants) that high, healthy foods so that the sweet potato called.
Crops Research Institute for Legumes and tubers produced some excellent sweet potato varieties that contain beta-carotene is new: the Papua and Papua Pattipi Salossa, each of which contains beta-carotene 533.8 mg / kg body weight and 245.3 mg / kg of body weight. It has also generated clones of sweet potato which contain high anthocyanin generally characterized the flesh of the tubers of sweet potato purple.
The results of research that anthocyanins play an important role in merepleksi and repair of DNA, which optimizes the function of body cells, thus preventing the aging process. This means that the consumption of sweet potato with high levels of anthocyanins on a regular basis has the potential to remain healthy and young.
With the role increasingly important and strategic to support food security also grow food and processed food not. Thus, opportunities exist to develop these two products. However, critical issues of the nature of this plant is also very serious and require appropriate solutions, including:
A cassava plantation on land are generally planted at the beginning of the rainy season, around October-November. Planting simultaneously at the beginning of the rainy season resulted in a cassava crop in July-August, with production so abundant that cassava prices low. This is related to the nature of cassava products, namely dry rot quickly or easily contract kepoyohan disease, due to physiological and pathological activity.
Within 24 hours the meat is exposed to air bulbs have begun to rot because it is difficult to storage. As for sweet potatoes, Bolenge pests that are difficult to control. sweetpotato farmers believe that the greatest enemies of pests Bolenge as plants, this pest damage caused to the quality of the tubers causing Bolenge down and result in losses that could reach 30-50%, even lower quality overall partial or bulb can not be sold or re-sale price low.
How this control Bolenge pest that can be done for example by improving agriculture are: dipping the cuttings with a solution of a selective and effective insecticides, crop rotation and good soil management.
INTRODUCTION
Sweet potato (Ipomoea batatas (L.) Lamb.) Represents a source of carbohydrates that can be harvested at the age of 3-8 months. In addition to carbohydrates, sweet potatoes contain vitamin A, C and minerals and anthocyanins that are beneficial to health. In addition, sweet potato is not only used as food but also as an industrial raw material and feed.
In Indonesia, the sweet potato as food is usually a side. While in Irian Jaya, sweet potato is used as a staple food. Both products grown in paddy fields and moors. The area harvested potatoes Ubu INDONESIA around 230,000 ha with a productivity of about 10 tonnes / ha. And with technology developed several high yielding varieties of sweet potato can produce more than 30 tons of wet tubers / ha.
PREPARATION OF THE EARTH
Sweet potatoes can be grown ditegalan or fields. Land preparation is to create an environment increasingly loose and fertile. Land and guludan and treated with a width of 40-60 cm and height of 25-30 cm
The distance between guludan 80-100 cm. In heavy soils (clay) to create a loose guludan need more than 10 tons of organic matter / ha.
HOW TO PLANTING
The sweet potato is planted after rice that is early to mid dry season. Inclusion of sweet potato in crop rotation with rice is very good in terms of sustainability, particularly the application of organic matter in sweet potatoes during the dry season.
Compactness about 35,000 to 50,000 plants / ha. With the distance between the lines / gulud 80-100 cm and 20-30 cm in rows. Seeds of shoot cuttings, seedlings grown tubers. Sweet potatoes can be grown in the intercropping system with a level not exceeding 30% shade.
Fertilization
fertilizer dose of 100-200 kg urea + 100 kg 100 kg SP 36 + 10 tons manure KCI / ha. Manure administered simultaneously to guludan. 1 / 3 dose of urea and KCl, and all the SP 36 given at time of planting. The remaining 2 / 3 of urea and KCl given at 1.5 months old plants. Applications of fertilizer should be covered with soil.
Weeding
Weeding is done before fertilization second. For the sweet potato is planted after rice, rice straw can be used as mulch can reduce weeding costs and the reversal of the stem. bars reversal of roles can be replaced by the use of mulch for the overthrow of the rod to prevent the emergence of the roots of stem segment.
Irrigation
sweet potato dry season crop, irrigated necessary to achieve high productivity. In addition, adequate irrigation to avoid the sweet potato against pests Bolenge Cylas formicarius.
CONTROL
The main pest is a pest Bolenge Cylas formicarius, Omphisa stem borer and the nematode Meloidogyne sp anastomasalis adverse sweet potato
DISEASE CONTROL
The major diseases of sweet potato cuttings is a fungus Fusarium sp. And scabies batatas Spaceloma
Harvest and harvest POST
Sweet potatoes can be harvested when the bulb is old and fat. Harvesting can be simultaneously or in stages. Physically, the sweet potatoes ready to harvest when the leaves and stems began to turn yellow.
Lowlands, sweet potatoes are usually harvested at the age of 3.5 to 5 months. Although high didataran sweet potato can be harvested at the age of 2-8 months.
After cleaning the floor and separated from tubers that are not supposed to, derived from stem to bulb up in the form of bonds depends on the purpose of final use. The bulbs are shipped kepabrik packaged in bags or in bulk. Although the bulbs are shipped outlets can be packaged in various forms depending on the tastes pasa, for example, tied or put in the basket.
Sweet potatoes can be processed into various forms of simple dishes, steamed, boiled, fried, roasted, baked or roast is a common way to prepare to serve sweet potatoes.
In addition to the direct consumption of sweet potatoes can be transformed into intermediate products in the form of starch or flour. The starch is made by extracting the bulb that has been shredded. Although yepung obtained by washing the tubers, peeling, slicing, drying and destroy (menepungkan) screened at 80 mesh. The starch and sweet potato flour can be used to create different types of cakes, noodles, ice cream.
