EXPANSION OF THE SET OF GRAIN CROPS IN THE REPUBLIC OF TATARSTAN

In the soil and climatic conditions of the Laishevsky municipal district of the Republic of Tatarstan, field experiments were conducted on the development of fertilizer systems for grain crops - spring triticale of the Timur variety and chickpeas of the Privo1 variety. Preparations of the "AgroNAN" series were used in the form of leaf feeding in different phases of crop development, and "Metallocene" for seed treatment, which are environmentally friendly micro fertilizers containing trace elements. AgroNAN Active has pesticide properties, AgroNAN Organic leads to an increase in the action of enzymes and assimilation from fertilizers by plants N and P. Metallocene D increases the stress resistance of crops and replenishes the shortage of Mg. Abnormally arid conditions of the growing season of 2021 subjected chickpea beans in the version without fertilizers to premature ripeness and shedding, which led to a decrease in yield. The least cracking of beans was in the fertilized versions. The combined use of Metallocene D (0.3 ml /t) preparations for seed treatment and AgroNAN Active (0.2 l/ha) in the form of leaf dressing during the growing season, with a purchase price for grain – 40,000 rubles / t, made it possible to harvest chickpea grain - 1.91 t/ha, which increased the profitability of production up to 464%. Despite the dry weather conditions, the yield of spring triticale was good, which, with the same background of fertilizers, corresponded to 5.3 t/ha, with a production margin of 292.4%, with a purchase price for grain of 12,000 rubles/t. The indicators of the above fertilized variants exceeded the data of the control variant by more than 1 t/ha.
