Pyongyang, July 17 (KCNA) — Researchers of the Dry-field Crop Institute under the Academy of Agricultural Science of the DPRK have succeeded in breeding new species of bean which can ensure a high and stable yield as after-crops.
They created the species from the mother system which ripens well and easily adapts itself to new circumstances and the father system which is strong in growth, by the system breeding method.
They, with a strong vitality, ensure high-yield with comparatively less amount of fertilizer.
The new ones are sown after wheat, barley and potato on the two-crop fields in the western coastal area and in the area south of Pyongyang between the closing of June and the beginning of July to reap in the beginning or middle of October.
The plant number per phyong (approximately one square meters) is more than 100-120 and the weight of 1,000 grains is 216 grams.
The years of cultivation tests show that their production is 20 percent higher than that of other after-crops bean species.
Researchers have also established the scientific and technical cultivation method for the new ones.
Pak Yong Chol, director of the institute, said in an interview with the KCNA that they had cultured high-yielding first-crop breeds and on its basis, made the new species. They would do their best to put the bean farming in the country, the home of bean, on a scientific basis, he added.
