Forestry management stations in Anju City, Phyongwon County and other parts of South Phyongan Province are gaining much economic benefit from the introduction of those reagents which help strengthening the functions of growth substances.

The reagents were developed by a research group of Sukchon University of Agriculture with locally available raw materials.

They promote the root growth of saplings, germination rate of seeds and growth rate of saplings and thus ensure the rooting rate at over 96 percent.

According to Yun Hyok Chol, vice-rector of the university, the reagents make it possible to multiply plants and crops in an industrial way.
