Popis: The modification of ‘the nearest neighbour’ method for using various size plots in field trials has been developed and the results of testing its validity by computer simulation are presented. It was found that the Field-S variant of this method using a square pilot area is the best for fields with a low and medium spatial heterogeneity. The Field-L variant using the least quantity of neighbours, offers advantages for fields with a medium and high spatial effect. The optimal values of the controlling coefficients of these variants were computed to allow for the calculation of the environmental indices over a wide interval of spatial heterogeneity with sufficient accuracy. For this reason, this local adjustment method is recommended as an obligatory statistical procedure for a prior data analysis of any field experiments that have fulfilled the necessary requirements. The original Field and CRBSD programs using the local adjustment method developed have been created for IBM-compatible personal computers.
