hedgerows were well established so they were more effective in preventing soil erosion than other
treatments
2.2 Farmer’s Adaptation and Adoption
After conducting two consecutive years of FPR trials, farmers were convinced of the
usefulness of vetiver hedgerows. They adopted the treatment and expanded it to a larger area in
their production fields. Farmers in Nakhon Ratchasima province actually combined three
treatments together: (i) using vetiver and chewing cane as contour hedgerows against erosion, (ii)
intercropping with pumpkin between cassava rows, and (iii) contour ridging.
