Multivariable analysis of effects of various methods of magnesium application of LG 2244 maize hybrid
Summary.

The paper presents a multivariable approach to the estimation of variability for quantitative traits after using the seven methods of magnesium application of the “stay-green” type of maize (Zea mays L.) hybrid. The 13 characteristics of LG 2244 hybrid were under consideration in three years (2006-2008): grain yield, moisture of grain, 1000 grain yield, dry matter of a single plant, dry matter yield, uptake of N, uptake of P, uptake of K, uptake of Mg, uptake of Ca, chlorophyll a, chlorophyll b and chlorophyll a+b content. The obtained results were computed with statistical multivariable methods of application. Canonical variable analysis (in each year independent) has proved to be an effective tool for clear assessing of differences among the studied methods of magnesium application. The most diverse methods were: C and E (in 2006), A and F (in 2007), and B as G (in 2008). The most similar methods (in respect of 13 traits simultaneously) were: B and C (in 2006), D and E (in 2007), and C and E (in 2008). Mahalanobis’ distances between methods of magnesium application in individual years of the study were not significantly correlated.

Key words: canonical variables analysis, maize, magnesium, Mahalanobis’ distances
