Study of the effect of new complex micronutrient fertilizers on the biological activity of crop seedlings

To obtain high and sustainable crop yields, one of the main conditions is the presence of the necessary trace elements. Macro- and microelements are a necessary component of the fertilizer system for a balanced nutrition of crops. Manufacturers are increasingly paying attention to microfertilizers, which contribute to the intensification of agriculture. The paper considers studies on testing the components of a new microfertilizer and its effect on the growth and development of grain crops, in particular wheat varieties "Moskovskaya 40", conducted at the Central Collective Use "Oryol Regional Center for Agricultural Biotechnology" of the Oryol State Agrarian University. The developed compositions of microfertilizers were used for presowing treatment of wheat seeds. It has been established that a new microfertilizer based on micro- and macroelements, humates and exometabolites of the fungus Trichoderma atrobrunneum VKPM F-1434 increases laboratory germination and germination energy in comparison with the control by 9% and 11%, respectively. There is an increase in growth rates and weight of wheat seedlings. So the length of the seedlings in comparison with the control exceeds by the end of the experiment by 28%, and their weight by 20%, the length of the roots is more by 36%, and the mass exceeds the control by 25%.
