Edge effects in cocoa shade and manurial experimental
The separate recording of "edges" and "cores" of the plots of a cocoa shade and manurial experiment has shown that the gross plot yield exceeds the guarded plot yield by about 17 percent. Previously published yields of this experiment have been based on unguarded plots and are presumably correspondingly in error, at least in recent years. (The edge effects may not have been so great in earlier years). At interfaces between manured and unmanured plots there was a substantial manurial edge effect, the edge rows of the unmanured plots apparently deriving almost as much benefit from the fertilizer as did the manured plots themselves.
