The research studied the influence of time periods and doses of nitrogen fertilizers on the activity of glutamine synthetase enzyme (GS), content of ammonia in the leaves, photosynthetic activity of planting and yield capacity of spring wheat grain. It was found out that GS was mostly active in the leaves in the blooming period. Nitrogen fertilizers in the dose of 2/3 of the calculated norm in the tillering period increased yield capacity by 1.32 t/ha in comparison with the control variant and by 0.31 t/ha in comparison with the variant where the whole norm of nitrogen had been introduced before planting. Fertilizers in the dose of 1/3 of the calculated norm of nitrogen improved the quality of spring wheat grain in the booting and blooming periods.
