ABSTRACT



In plant breeding field trials plant competition effects can seriously distort the treatment contrasts. To detect the effects, the special designs, known as competition designs, should be applied. In the study the so-called competition diallel with 5 genotypes was used to estimate the competition effects in pea, faba bean and yellow lupin. For each species the two trials with 1- and 3-row plots were established. Soil samples were taken to assess spatial soil variation. The semivariances of soil properties (pH, P, K, Mg) were calculated and semivariogram models were fitted. Finally, kriging was applied to predict the values of the soil properties for each plot. The general linear models were applied to estimate the magnitude of neighbor effects and the spatial effects of soil variation. The competition effects were calculated according to the competition diallel model using original data and residuals after elimination of soil spatial effects. The competition effects in yield of grain legumes depended on the plot size as well as on the species and its growth habit. The competition effects in 1-row plot experiment ranged from 10 to 40% in pea, 10 to 30% in faba bean and 10 to 100% in yellow lupin. For the 3-row plot experiment the effects ranged from 0 to 10% in pea and faba bean and 5 to 50% in yellow lupin. The competition analysis with additional information on soil variation in comparison with the analysis using the original plot data may extend the interpretation of specific competition relations between the genotypes of a given crop.

Key words: pea, faba bean, yellow lupin, field trials, plant competition, geostatistical methods.
