Poprawa wartości pokarmowej ziarna pszenicy jarej poprzez siewy mieszanin odmianowych

2020 
The aim of the study was to determine the content of nutrients and bioactive substances in two- and three-variety mixtures of spring wheat in comparison to varieties growing in pure stand and to demonstrate whether this method of grain production allows, in addition to better yielding, improvement of its nutritional value. The material for analysis consisted of 14 varieties and 60 varietal mixtures, including 10 two-component mixtures harvested in the years 2014, 2016 and 2018. The content of protein, lipids, minerals and starch, constituting nutrients and dietary fibre, including its basic components and phenolic compounds, was determined as bioactive substances of cereal grains. The results showed that the improvement of the end-use value is possible by cultivating spring wheat varietal mixtures. The genetic factor had a significant impact on the content of nutrients and the complex of dietary fibre in the variety mixture of spring wheat. Identification of suitable varieties for mixed sowing is necessary to improve the nutritional value of spring wheat.
