Influence of Nitrogen Fertilization on Biomass Accumulation of the Brewer’s Spring Barley
Published on: 2019-02-19
The objective of this study was to analyses the nitrogen fertilization effect on biomass accumulation and grain quality of the brewer’s barley. The study was conducted in randomized blocks with 4 replicates in Warsaw Agriculture University Experimental Field in Chylice. The experimental factors were: three cultivars of spring barley (Maresi, Poldek and Rasbet of chaffy grain) and nitrogen doses (0, 30, 60, 90 kg N/ha). The size of grain yield and protein content in the grain of brewer’s spring barley is closely dependent on nitrogen fertilization. The highest nitrogen fertilization used in the experiment (90 kg/ha) increases the protein content in the grain above the allowed norm, making it incompetent raw material for the brewing industry. The condition to produce high dry matter by the plants of brewer’s spring barley is constant and high relative growth rate since the beginning of the growing season, so the growing of barley should be focused on obtaining fast-growing form.
