Introduction to the Ground Apple or Yacon
Many of us are familiar with apples that grow on tree. But there exists another fruit called ‘ground apple’ that is gaining ground among the Nepalese farmer. This fruit, otherwise called ‘Yacon’, is believed to
have entered Nepal from Japan, 10 years prior. Origin of this fruit are considered to be Peru and Bolivia in South America.
The plant grows up to two meters tall and the leaves are light green and long. Each year, one to four dozen dark red or purple sprouts sprout around the base of the plant. Each sprouted seedling is transplanted as a separate seedling from the Mid-March to first week of April in sandy loam soil with hot and humid climates in suitable land or areas of suitable height. This fruit is harvested by digging the ground from November to January of each year. At the root of a plant 15-20 fruits of about 10-15 kg can be found. One fruit weigh up to 2-2.5 kg.
About 15 days after the fruit is dug out of the ground, it is washed peeled away and the juicy light red part is cut into different pieces. When eaten, it is slightly sweet, tasty and has its own lights aroma. In term of nutrition, it has been found to be placed in the rank of highly nutritious fruits. This fruit is rich in iron, calcium, sodium, potassium, chlorine, magnesium, vitamin B-1, B-2 and vitamin C. It has been found to balance 60-70 percent of blood glucose and also contains insulin. So, it is called healing plants and is counted among the fruits containing super nutrition.

Possibility of Production and Trade of Ground Apple (Yacon) in Nepal
As Nepal is an agricultural country and there is considerable diversity in its topography and climate,
cultivation can be done on Nepalese land from 1500 meters to 3000 meters above sea level. On the other hand, as the demand is increasing in all the developed countries of the world and the interest in it is also increasing in the developing countries, there is ample potential to expand its production and export from Nepal as well. It also has the potential to solve employment problems by expanding its production, trade and consumption, as well as strengthening public health. In addition, due to its quality and market value as compared to other fruits and its good position in the international market, its production,consumption and trade are considered to be extremely profitable and healthy.
A decade ago, it was first cultivated as a trial in Kakani and Kathmandu Valley, but then it was cultivated sporadically in Kavre, Makwanpur, Godawari and Lalitpur. ICIMOD, an environmental organization has also been cultivating it as a sample trial for several years.
In the last two to three years, conscious farmers of some districts like Nuwakot, Rolpa, Rukum, Rasuwa, Makwanpur, Gorkha, Dolakha, Myagdi, Baglung, Lamjung, Gulmi and other districts have increased their interest in its organic production. Recently, it has started selling nationally and internationally through Agricultural product and Marketing Centre Pvt.Ltd.
