Prenial peanut is promoted as an excellent green manure cover crop. We have tried using it… with mixed results. Are we alone in our experience? We are in southern Philippines lowland humid tropics with pronounced dry season.
We are just harvesting cassava planted last November. Part of the field has a covering of perenial peanut. Under this the cassava roots were very small, the rest of the field they were much bigger. It was also much more difficult to harvest due to the root mat. the guy harvesting reckons it is alos not good to use with bananas. We also have guavas, a few of which we planted perenial peanut under and they now have a thick mat. However they look no different (better or worse) than the ones with grasses under them. The maintenance treatmetn for both is the same - mowing.
