Assessment of the Influence of Meteorological Factors and Agricultural Background on the Productivity of Spring Wheat Ulyanovskaya 105 in the Predkamye of the Republic of Tatarstan

The most valuable and widespread food crop is spring wheat. Soil and climatic conditions influence the grain productivity and quality. The grain quality is affected by air humidity, insolation, nitrogen content in the soil and agricultural technologies. In 2019–2020, on the experimental field of the agronomic faculty of Kazan State Agrarian University, studies aimed to identify the reaction of the Ulyanovskaya 105 spring soft wheat to meteorological conditions and agricultural background were carried out. The soil was light gray forest, medium loamy. The predecessor was winter rye after pure fallow. Meteorological conditions were favorable for the growth and development of spring wheat. In 2019, the HMC was 1.36, in 2020 – 1.13. The maximum yield in 2019 and in 2020 was obtained with the application of calculated doses of fertilizers when sowing 6 million viable seeds per hectare – 3.0–3.44 tons and 3.67–4.21 tons per hectare
