Abstract
Uniformity trials in cashew (airlayers) were laid out is the existing cashew estates at Periya, Kasaragod district, belonging to the Plantation Corporation of Kerala. The yield data from 288 trees (24 rows of 12 trees each) were collected for two year 1982-83 and 198344 by daily harvest Fair field Smiths Law Y = ax and Its generalisation y=ac-s1 where g s stand for the heterogeneity coefficients expressing the reiationship between plot size (x) in r rows of c column and the C. V. (Y) of yield were tried Graphical method and maximum curvature technique were used for working out the optimum plot size. Further the cost of experimentation per treatment to estimate the means at 10% S E. was worked out for different price situations. A plot size or 6 rows of 2 trees each forming the plot across the fertility lines was found to be the optimum for experiments with cashew.
