Studies show that the application of nitrogen fertilizers and glauconite sand positively affects the yield of winter wheat. Applying 120 kg of nitrogen increases the grain content in the ear by 11.3%, and adding 1 ton/ha of glauconite sand along with nitrogen increases the number of grains by another 3.9%. The grain mass per ear increases by 5.1-5.9% when using 1-2 tons/ha of glauconite sand. As a result of fertilization, the weight of 1000 grains of the "Yanbash" variety increases by 1.7-2.4%. Winter wheat yield increases by 62.3% when nitrogen fertilizers are applied, with an additional yield increase of 13.4 centners/ha. Using 1-2 tons/ha of glauconite sand on the N120 background further increases the yield by 5.8-5.0 centners/ha. Thus, the application of glauconite sand allows achieving high yields without the use of phosphorus-potassium fertilizers, providing the plants with the necessary nutrients and improving the chemical composition of straw and grain.
