BAKING QUALITIES OF WINTER CROPS IN THE MIDDLE PREDURALIE
The effect of nitrogen top dressing on grain quality of winter wheat, winter triticale and winter rye was studied in the conditions of Permskii krai in 2013-2015. The experiment was laid down at the experimental and training field of the Perm State Agro-Technological University as follows: factor A - crop: A<sub>1</sub>-rye; A<sub>2 </sub>- wheat; A<sub>3 </sub>- triticale; factor B - dose of nitrogen, kg/ha: B<sub>1 </sub>- 0; B<sub>2 </sub>- 30; B<sub>3 </sub>- 60; factor C - term of fertilizing: C<sub>1</sub> - physical maturity of soil at 0-5 cm soil layer; C<sub>2</sub> - 5 days after the first term; C<sub>3 </sub>- 10 days after the first term. The content of humus in arable layer is 2.3 2.0%, of mobile phosphorus 74-142 mg, exchange potassium 120-304 mg/kg of soil, pH<sub>sal</sub> 5.6-6.3. Spring-summer period of plant development in 2014 was characterized as cool (average daily air temperature was below normal ranged from -0.7 to -4.5° C) and humid. Spring and summer period of plant development in 2015 was characterized as warm. The average air temperature in May was 13.4° C, in June -18.6° C. The weather in 2016 was warm and dry. Precipitation was 5 times lower than the norm. The dependence of the baking qualities on doses and timing of nitrogen fertilizing was established. Their response to the level of nitrogen nutrition was determined. Application of nitrogen feeding increases the nature of grain, falling number, glassiness, fraction of total mass of crude gluten. Flour and baking quality do not depend significantly on the nitrogen fertilizing.
