Abstract: This paper deals with the influence of Mg, N and the content of chlorophylls and carotenoids on photosynthetic productivity of two new genotypes of winter wheat, Lara and Perla, at two localities, Donji Miholjac and Kutjevo, during the vegetation periods 1997/1998 and 1998/1999. The applied parameters were determined by standard methods. The results showed effects of Mg concentration on all examined parameters with the exception of chlorophyll b content. The highest correlation coefficient was with the N concentration, significant correlation between the leaf area and N concentrations and between the leaf area and chlorophyll a. Statistical analysis showed very significant relationship between the content of organic matter and examined parameters with a large number of significant correlations. The most important correlation was found between the content of organic matter and N concentration, and between chlorophyll a, chlorophyll b, carotenoids and the content of organic matter. The link between N, Mg and other examined parameters was firm and significant as well as under strong influence of external factors.
