Summary. Studies were carried out under conditions of Tomsk region in 2011-2014 in five-field crop rotation: fallow, wheat, wheat, Sudan grass + leguminous, barley. The aim of the investigation was to determine the influence of fertilizers containing trace elements on yield of grain crops and fodder mixture Sudan grass + beans. The soil is grey forest, moderately podzolized and loamy; humus content is 3.9-5.2%, content of (N-NO3 + NH4) is 7.6-11.9 mg/kg, of mobile P2O5–16,1 mg/100g, of exchange K2O–10.4 mg/100g. The soil is characterized by low availability of mobile forms of trace elements (molybdenum, copper, magnesium, boron). For presowing treatment of seeds complex fertilizers containing trace elements were used: hydromix (200 g/t), aquarin 5 and aquarin 9 (2 kg/t). With the use of these fertilizers plant height of wheat increased by 2.0-5.4 cm, barley–2.3-4.6 cm, bean and Sudan grass–1.9-16.2 cm. Simultaneously, the injury of grain crops by Alternaria decreased 2.1-2.7 times. Presowing treatment by hydromix, aquarin 5 and aquarin 9 promoted increase in the yield of wheat by 9.4-18.9%, barley–24.0-28.6%, the green mass of Sudan grass and beans mixture–6.8-13.4%. The highest yield increase was obtained in the variant with aquarin 9. With the use of fertilizers, containing trace elements, the gluten quantity in wheat grain increased by 3.4-5.6%, the protein content in barley grain–by 1.3-1.6%, total yield of protein per 1 hectare of Sudan grass with beans–by 11-21%.
Keywords: fertilizers containing trace elements, application efficiency, grain crops, forage mixture.
