The article presents the results of research on the effectiveness of ammophos, sulfoammophos and urea modified with nitrification (DMPP) and urease (NBPT) inhibitors when applied to spring wheat. Field experiments were carried out in 2022–23 on cultivated light loamy soddy-podzolic soil on the territory of the Field Experimental Station of the Russian State Agrarian University – Moscow Timiryazev Agricultural Academy. It has been shown, that the application of inhibitors with ammophoska and urea increases grain yield by 12–14% and increases protein yield by 10–15%.

The authors carried out studies at the experimental field station of Russian State Agrarian University - Moscow Timiryazev Agricultural Academy in 2008-2020. The study aimed to determine the resistance of white clover in mixtures with various types of grasses with two- and three-cut clipping treatments. In the experiment with four to five-component mixtures, the proportion of white clover reached 36-53% in the botanical composition of swards with the content of perennial ryegrass in the fourth year of life. It did not exceed 22-23% in the mixtures with cock’s foot.
