ABSTRACT: The aim of this research was to study the influence of increasing doses of mineral fertilizers, time and methods of introducing potassium humate and combinations thereof, on barley yield and grain quality. The results of the research showed that the highest grain yield of polystichous barley (2.85 t/ha) occurred after the introduction of mineral fertilizers N₉₀P₉₀K₉₀ kg/ha of a.m. (in the amount of 90 kg/ha of active material). The use of potassium humate for cultivation + seed treatment + spraying plants during the tillering phase + during the earing phase contributed to its increase (2.60 t/ha). By individual characteristics it had an advantage (3.32-3.35 t/ha), when the same variants were used. The maximum accumulation of crude protein, fiber and fat was observed after the introduction of potassium humate and mineral fertilizers N₁₂₀P₁₂₀K₁₂₀ kg/ha of a.m.
