ABSTRACT

The problem of the effective control of
soil variability is the main limitation on the broader use of factorial or fractional
designs in agricultural experimental practice. The objective of the study was
to assess the usefulness of some soil (pH, P, K, Mg, organic C) and plant traits
(plant height, seed yield) for the estimation of spatial variation of the experimental
field and to assess their usefulness in increasing the efficiency of 3⁵ field
plot experiment with pea. Geostatistical methods were used in spatial analyses
and ANOVA and ANCOVA in the analyses of the data from the experiment. The relative
efficiency of the ANCOVA with information on spatial variation compared to the
classic ANOVA was calculated. All of the studied soil properties and plant traits
were spatially autocorrelated. The experimental semivariograms were transitive, having the range and the sill fitted
with the spherical and exponential models. The range of spatial autocorrelation for soil properties was 18.5-73.7 m and for
plant traits 1.6-3.7 m, while the share of structural variance (C) in the variance
of sill (C₀ + C) was 60% and 90% for soil properties and plant traits,
respectively. The values of spatial descriptors predicted
for each experimental plot by kriging and used as covariates in ANCOVA resulted
in higher efficiency.

Key words: field experiments, factorial design at three levels, geostatistics, spatial variation.
