Yield and quality of bitter and aromatic hop varieties depending on the level of mineral nutrition in the soil and climatic conditions of the Republic of Belarus

Abstract

The soil and climatic conditions of the Republic of Belarus are favorable for the growth and development of various bitter and aromatic hop varieties from different regions of the world. Of the cultivated bitter varieties, Hallertauer Magnum Bel (11,5– 13,3 c/ha) are distinguished by the yield level of cones, Pearl Bel (9,5–11,2 c/ha) from the aromatic group, and Hallertauer Magnum Bel (12,7–13,2 %) and Northern Brewer Bel (10,1–12,3 %). It should be noted the high potential productivity of the Pearl Bel variety, which is characterized by a large number of forming cones (4504–4783 pcs.) and maximum leaf mass (11.5–14.5 c/ha). The highest coefficients of the β/α acid ratio were obtained in Thettnanger Bel varieties (1,00–1,04). The effect of various doses of nitrogen-phosphorus-potassium fertilizers on the yield of hop cones has been established.
