MAGNESIUM STATUS IN CORN (Zea mays L.) HYBRIDS AND ITS RELATIONS TO POTASSIUM AND CALCIUM

Twenty corn (Zea mays L.) hybrids were grown under the field conditions during the 2000 and 2001 growing seasons. The ear-leaf at the beginning of the skilling stage was taken for chemical analysis. The experimental field was acid hydromorphic soil with moderate levels of mobile fractions of megnesi...

Description
Summary:Twenty corn (Zea mays L.) hybrids were grown under the field conditions during the 2000 and 2001 growing seasons. The ear-leaf at the beginning of the skilling stage was taken for chemical analysis. The experimental field was acid hydromorphic soil with moderate levels of mobile fractions of megnesium (Mg), calcium (Ca) and phosphorus (P). In our testing considerable influences of growing season (mean 0.273 and 0.177 mg Mg/kg, for 2000 and 2001, respectively) and heredity (range of 2-year means among the 20 hybrids: from 0.120 to 0.291 mg Mg/kg) were found. Three corn hybrids (OsSK395, RK1456 and OsSK332) had low Mg (
