PLOT-SIZE IN YIELD SURVEYS [PDF]
Nature, 1947 RECENT communications by Sukhatme1'2 and Mahalanobis3 have established the conclusion that sample plots of a small size (25 sq. ft. or less according to Mahalanobis) give biased estimates of yield in sample surveys ; but whereas Sukl tme has shown the bias to. persist evenwith a plot-size of 118 sq.

Estimation of Optimum Plot Size in Split-Split Plot Design Used in Field Experiment [PDF]
The Egyptian Statistical Journal, 1999 Estimates of soil heterogeneity are obtained from Split-Split plot design. A weighted regression analysis method is used to determine the soil heterogeneity from the analysis of variance technique of the above design.

Heterogeneity, plot shape effect and optimum plot size
Geoderma, 1994 By introducing heterogeneity indices, an empirical equation is proposed for characterizing the heterogeneity of non-isotropic fields. The formula is an extension of Fairfield Smith's (1938) empirical law describing heterogeneity in isotropic fields. Based on these indices, criteria are provided for choosing optimum plot shapes in terms of minimizing ...

Plot size and shape for Sesame experiments
OBSERVATÓRIO DE LA ECONOMÍA LATINOAMERICANA, 2023 In agricultural experimentation, the use of adequate plot size and shape is an important experimental technique to increase the precision of the experiment. Thus, the objective of this study was to determine the appropriate size and shape of the plot for field experimentation with sesame.

Optimal plot size in wheat with comparison of three methods [PDF]
Revista Ciência Agronômica, 2023 The objectives of this study were to determine the optimal plot size (Xo) to evaluate the fresh matter productivity of wheat (Triticum aestivum L.) and check whether Xo differs between three determination methods. Five uniformity trials were carried out.
