Effect of cultivation system on quality changes in durum wheat grain and flour produced in North-Eastern Europe

Abstract

Grain of the highest hardness was produced from durum wheat grown without the growth regulator, at the lowest sowing density (350 seeds m-2) and nitrogen fertilization dose of 80 kg ha-1. The highest values L* and b* were determined in the grain of wheat cultivated without additional agrotechnical measures (growth regulator and nitrogen fertilization). Study results, supported by correlation analysis, indicated that high-quality grain with desired flour quality parameters (extraction rate, granulation and lightness) can be produced from spring durum wheat grown without the growth regulator and at medium doses of nitrogen fertilization. Additionally, this variant of applied cultivation system can reduce costs of durum wheat production and contamination of the natural environment.
