ALTERNATIVE METHODS TO DETERMINE PLOT SIZES FOR TREE CROPS: A CASE STUDY FROM COCONUT DATA

Abstract

Two methodologies are proposed to determine the most efficient plot
size for tree crops using data from experiments based on randomized complete
block designs. Both methods can be generalized for data from any
balanced design. The merits and demerits of these methods are discussed.
The methods are illustrated using the data sets of long-term field experiments
at the Coconut Research Institute, Sri Lanka. The results show that
efficient plot size in field experiments for coconut for a wide range of agroecological
regions is four or six palms.
