Abstract. The purpose of the research is to study the influence of the main technological methods of cultivation on the formation of the crop and grain quality of new varieties of soft winter wheat breeding North-Cavcasus FARC. Methods. Statement of field experiment and generalization of research results are made in accordance with the methodical instructions of B. A. Dospekhov. Accounting harvest was performed with the combine method. Technological assessment of winter wheat grain quality was determined according to GOST R 54478-2011. Results. The conducted researches showed that on the predecessor pure steam the studied new grades of a winter wheat form not only a big crop, but also the best quality of grain, in comparison with the predecessor a winter wheat. So, on average in grades for 2015‒2018 productivity and amount of crude gluten of a winter wheat in our experiences on the steam predecessor on control made, respectively, 5.0 t/ha and 17.5 %, and on the winter wheat predecessor ‒ 3.4 t/ha and 16.4 %. Improvement of conditions of mineral food provided increase in productivity and amount of crude gluten on the predecessor pure steam, respectively, on 2.2 t/ha and on 5.9 items, and on the predecessor a winter wheat – on 1.7 t/ha and on 2.2 items. Our researches showed that on the sum of the indicators defining stability of a grain yield and its quality, the most perspective grades are the Stavka and Stat’. The scientific novelty consists in that, for the first in the conditions of unstable moistening of Stavropol Krai influence of various elements of technology on productivity and quality of grain of a winter wheat of new grades of selection of the North-Cavcasus FARC is studied.
Keywords: winter wheat (Triticum aestivum L.), meteorological conditions, yield, grain quality, variety, precursor, mineral nutrition.
