abstract:
The experiment was carried out at the Department of Plant and Soil Cultivation, Agricultural University of Poznań, in 2004-2005. It comprised four doses of nitrogen: 0.6; 1.2; 1.8 and 2.4 g N pot-1, and 2 methods of fertilization: broadcast and point application (with fertilizer placed 5 cm off the side and 5 cm below the grains), and 2 kinds of grains (without inoculation and with inoculation with F. culmorum). The influence of nitrogen content in the soil, the way of application and additionally the way of fungal inoculation with F. culmorum on the content of chlorophyll was determined. Plants used in the experiment were at the stages of 3-4 and 4-5 fully developed leaves. The better method of nutrient application proved to be the in-row fertilization. Inoculation of seeds with F. culmorum decreased the content of chlorophyll.
