2013, Department of Agriculture and Rural Development of Bac Kan deployment model testing techniques in cultivation of arrowroot My Phuong Commune (Ba district) aims arrowroot choice varieties with high yield and quality , find suitable farming practices with soil conditions and climate of the province, creating the raw materials for the processing industry of the province arrowroot develop stable and sustainable.

Accordingly, the Department of Agriculture and Rural Development of Bac Kan has studied some of the same tests as arrowroot and prospective trials on the effects of nitrogen doses on yield, quality and economic efficiency arrowroot galangal in production. The model uses the same 6 arrowroot is derived from the Institute of Food crops, food crops and two local varieties that farmers have planted as controls on 3ha in area Na cilantro, My Phuong Commune (Ba).

Through monitoring and evaluating experimental models that, just like V.CIP arrowroot DR3 and the highest yield, reaching 120-140 tonnes / ha, much of the local arrowroot (used as controls) only 48 tons / ha. According to the people's participation model, arrowroot varieties are 240-285 days growth period, the percentage grows well, the growing quite.

On testing the effects of nitrogen doses on yield, quality and economic efficiency that formula 5 tons of organic fertilizer + urea 200kg + 500kg + 200kg potassium phosphate, 2 khom/m2 planting density, yield from 96-120 tons / ha. This is a model farmer can apply universally.
