Influence of pre-sowing treatment of seeds with zinc and copper chelates on yield and grain quality of spring wheat cultivated in the forest-steppe of Western Siberia

One of the problems of mineral nutrition of crops in Western Siberia is the lack of trace elements in the soil, including available compounds of copper and zinc, so it is necessary to study the use of microfertilizers in crop production in the region. The aim of the research is to study the effect of pre-sowing treatment of seeds with zinc and copper chelates on the yield and quality of spring wheat grain when cultivated on meadow-chernozem soil. Field studies were carried out in 2017-2018 in the fields of Omsk Agrarian Research Center, laboratory studies - at the Department of Agrochemistry and Soil Sciences of Omsk State Agrarian University. The object of research was the variety of spring wheat “Pamyati Azieva”. The content in the 0-20 cm soil layer of nitrate nitrogen, labile phosphorus, exchangeable potassium is high, while that of labile zinc and copper is low. The forecrop was coulisse fallow, the agricultural practice was the one commonly applied in the area. Applied zinc and copper chelate fertilizers positively affected the yield and quality of spring wheat grain...
