Abstract

The article shares resource-saving technologies of growing soft spring wheat (Triticum aestivum L.) in the non-chernozem zone of the Russian Federation based on modern agrotechnical methods involving combination application of plant growth regulators and chelated fertilizers Epin Plus, Epin Extra, and Cytovit. Such technics increase yields, improve the quality of grain, and increase biomass. Field studies for 2022 - 2024 years described positive effects on morphological parameters such as height of plants, length of ear, number of spikelets and grains per ear and weight of 1000 seeds. The greatest results were obtained when Epin Plus and Cytovit were used in aggregate. Grain yield increased by 35,16%, straw by 37,3%. Protein, gluten, and glassy content of grain have increased by 15,86%, 17,89%, and 22,19% respectively compared to the control group. The data obtained demonstrate the high efficiency of an integrated approach to agrochemicals aimed at improving the productivity and technological characteristics of grain crops. This contributes to the sustainable development of agriculture in the non-chernozem zone and the rational use of resources.
