Modeling of spring wheat yield with differentiated seeding and mineral fertilizer application

One of the most effective methods for increasing the yield of spring soft wheat is the improvement of its cultivation technologies, the use of differentiated seeding and the targeted application of mineral fertilizers. The development and implementation of precision farming tech- nologies are becoming important tools for agricultural production. The purpose of the work is to evaluate the agronomic efficiency of using various seeding rates and doses of granulated and liq- uid mineral fertilizers when cultivating spring wheat in the steppe zone of Novosibirsk region. In 2024, the agronomic efficiency of differentiated nutrition systems for spring wheat of Predgornaya cultivar with the same seeding rate; the agronomic efficiency of differentiated nutrition systems for spring wheat and the agronomic efficiency of differentiated nutrition systems for spring wheat with the same dose of mineral fertilizers were studied in three fields of the farm at Rubin LLC in Krasnozersky district, Novosibirsk region. The analysis of the results showed that the most signif- icant influence on the wheat yield was exerted by the field fertility zone (X3), in second place was the dose of mineral fertilizers (X2), and in third place was the seeding rate of wheat seeds (X1 ). It has been established that the use of different doses of mineral fertilizers and seeding rates by field fertility zones has a very significant effect on the structure of the harvest, the amount of costs and economic efficiency. Therefore, the correct use of differentiated seeding and fertilizer application by soil fertility zones in the fields is one of the most significant areas for increasing the efficiency of grain production.
