Stabilizing and limiting factors of yield formation of spring barley.

Popis výsledku v původním jazyce

In the yers 1990 to 1992 and 1996 to 1998 the effect of nitrogen fertilization (rates of 0, 30, 60, 90 and 120 kg N.ha-1) and soil fertility on yield formation of spring barley was studied in micro-plot trials. In the first three year trial a main criterion of soil fertility were the grain size structure and humus content (< 1 %, 2 % and > 3,5 %). In the second three year experiment a main criterion was the soil pH level. It follows from the results that the productivity of spring barley, variety Jaspis, grows with graduated content of humus and gradated rates of nitrogen fertilization. Regarding the grain and straw yields of spring barley, the most efficient in most soils is a rate of 60 kg N.ha-1. Statistically significantly efficient are rates 90 and 120 kg N.ha-1 on soils with medium humus content. A good correlation were found between spring barley productivity and the content of soil total , mineral and mineralizable nitrogen. The soil acidity decreased the productivity of spring
