Abstract
IN the past, large yield fluctuations within treatments in cacao fertilizer experiments have proved difficult to understand. These fluctuations, frequently occurring between adjacent trees, necessitate an unwieldy degree of replication before a sensible level of error variance is obtained within the experimental area. It is important to know the cause of these fluctuations, not only to reduce to a minimum the acreage required for field-experimentation with cacao but also to help in understanding the behaviour of tree crops and of cacao in particular.
