Phkar Rumdoul is sown directly into the mulch of Stylosanthes guianensis and Centrosema pascuorum without soil tillage and puddling. The field is located  on the upper part of the Stung Chinit irrigation scheme (80% sand, less than 1% of organic matter in 0-10 cm depth) with limited water accessibility. This system reduces soil evaporation, decreases soil surface temperature, increases soil organic C and N contents, allowing for better water and nutrients use efficiency and profitability.

Stylosanthes guianensis during the immature stage of rubber plantation

On relatively poor soil, the maintenance of rubber plantation during the vegetative development (immature) stage is very expensive, and it has much low potential for inter-cropping with annual crops. Stylo could be used as cover crop and fodder to minimize considerably the maintenance costs, improve the soil fertility and potentially integrate with livestock production.
