Chestnut tree planting goes full steam ahead in the DPRK.
Songchon chestnut, Taesong chestnut-1 and other chestnut trees yield 3 to 5 tons of fruits per hectare. The chestnuts contain 20 percent of sugar content and large amounts of starch, protein and fat.
More than one million chestnut saplings of superior grain species are produced every year by introducing a method of producing saplings through cleft grafting.
This year, chestnut trees were planted in thousands of hectares of land across the country.
