INFLUENCE OF BIOLOGICAL STIMULATOR AND CULTIVAR ON QUALITY INDICATORS OF SPRING WHEAT

Abstract

The soil of the experimental site was leachate (Calc(ar)ic Luvisol). The purpose of the study is to investigate and compare the quality indicators of different spring wheat varieties after using a biological stimulator. The experimental soil was of neutral acidity (pH 6.5), with an average phosphorus content (169.0 mg kg^-1 P₂O), as well as an average potassium content (121.2 mg kg^-1 K₂O) and an average humus content (2.27 %). Factor A - biological stimulator "Biomas Grow". Factor B - different spring wheat varieties ′Flippen‵ and ′Collada‵. The biological stimulator "Biomas Grow" is used, the spraying rate on germinated cereals was 0.1l ha^-1. The used biological stimulator had no effect on spring wheat protein content in grain, but increased sedimentation, wet gluten content, number of falls and hectoliter weight in both varieties of grain. The spring wheat variety had no significant influence on grain quality indicators, but the amount of wet gluten, the number of drops and the weight per hectoliter were higher in the 'Collada' variety, but the use of the biological tool 'Biomas Grow' increased the yield of both varieties of spring wheat in 'Flippen' - by 18.9 %. "Collada" - 28.8 %, 23.3 % more fertile was 'Collada' - a spring wheat variety compared to the 'Flippen' variety.
