Abstract

This article analyses and evaluates the effect of the level of nitrogen supply at different sowing dates on the yield and grain quality indicators of the newly developed local winter soft wheat variety “Aqmang‘it”. According to the results obtained, the highest yield was 93.4 c/ha, achieved at the sowing date of 20 September with a nitrogen rate of 200 kg/ha. When sowing was delayed until 10 October, the yield ranged from 73.1 to 83.3 c/ha, that is 10.1–19.3 c/ha lower than at the optimal date. The optimal sowing date and nitrogen rate for making full use of the high biological potential of the newly developed local “Aqmang‘it” variety have been scientifically substantiated.
