"Seven varieties of buckwheat Fagopyrum esculentum Moench ( Pyra (Czech Republic), Lifestum (Germany) (1997), A-elite (Russian Federation) (1998-1999), Emka (Poland), Hruszowska (Poland), Kora (Poland), Krupinka (Russian Federation), Sum\u010Danka (Russian Federation)). were cultivated in \u010Cesk\u00E9 Bud\u011Bjovice during years 1997 - 1999. No fertilisation was applied. Chemical composition was analysed in buckwheat grains - content of nitrogenous compounds was determined according to Kjeldahl, fat content according to Soxhlet, fibre content according to Scharrer and K\u00FCrschner, amount of phosphor and calcium according to Lorenc, and content of phosphorus, calcium and ash compounds by weight method. The highest of proteins and minerals content was established by variety Pyra. The statistical signification of variety influence at the tested parametres by the analysis of variance was not observed. The high statistical signification of year influence at content of nitrogen, sugars, minerals phosphorus and calcium wa"@en . "[063AC3448EC5]" . "Kalinov\u00E1, Jana" .
