Our 3 Maize Cluster Farm Groups are from 3 different sub-districts of Nanoi District, Nan province, Thailand. Nanoi District is the 2nd phase district of Nan province that produces maize (around 70,000 rai). Average maize production area is 10-150 rai per household with average yield of 600-700 kg./rai. The three groups produce both maize and coffee. Main coffee variety is robusta. The DOAE plans to implement the 3Rs Model for crop switching (maize to coffee) with 80 farmers by 700 rai.
