Yield and quality of winter rye in the regulation of nutritio by nitrogen top dressings

The research objective was to give comparative assessment of the influence mineral nitric fertilizers top dressing on nutrition conditions, productivityand quality of grain of a winter rye of the varieties of Yeniseika and Atlanta. The researches were conducted in JSC ‘Tigritskoye’ of Minusinsk area of Krasnoyarsk Region. In 2016-2017 field experiments on leached heavy loam chernozem were made.

For each option of the experiment in production crops of a winter rye allotments with the sizes of 100 sq.m in fivefold frequency were allocated. The increase of the content of general moisture in the soil after nitric fertilizers top dressing at the expense of economical expenditure of moisture fertilized plants was established. The increase in the soil of amount of nitrate nitrogen, especially on options with top dressing by ammonium nitrate was recorded...
