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 use of 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 (level of: FER 64%; FPS 98%; L* 92) can be produced from spring durum wheat grown without the growth regulator and at 80 kgha-1 nitrogen fertilization. Additionally, this variant of applied cultivation system can reduce costs of durum wheat production and contamination of the natural environment.
