Abstract
Description
The paper presents results of field studies, examining
the effects of application of different forms of nitrogen fertilizers
and magnesium on the dynamics of dry matter accumulation in
the early growth stages of two hybrid types of maize. The experiment
determined dry matter yield at the 5–6 leaf stage, absolute
growth rate (AGR) of dry matter, macronutrient contents
and their uptake. It was shown that the type of nitrogen fertilizer
and the dose of magnesium do not significantly differentiate the
dynamics of the early growth in maize expressed by the amount
of dry matter and absolute growth rate for dry matter. It was found
that the stay-green cultivar ES Paroli had a significantly higher
dry matter yield at the 5–6 leaf stage than the conventional cv.
ES Palazzo.
