The article deals with the influence of biological products and complex fertilizers with microelements in a chelated form on the formation of parameters of photosynthesis, symbiotic activity and productivity of clover of the Pannonian variety ANIK. It was found that inoculation of seeds with biological products of the associative group and complex fertilizers with microelements in a chelated form activated growth, morphogenetic processes, symbiotic and photosynthetic activity of Pannonian clover plants. The number and weight of active nodules in relation to the control increased by 29.2-167.6 million pl./ha and 77.7-564.1 kg/ha, respectively. The maximum parameters of the symbiosis of the agrocenosis of Pannonian clover (active nodules 221.8 million pl./ha with a weight of 893.7 kg/ha) were formed when clover seeds were inoculated with the biological product Gumariz together with the silicon-containing preparation NanoSilicon. The highest indicators of the leaf surface of clover, 53.6 thousand m2/ha, were observed during the complex seed treatment with Gumariz together with the NanoSilicon preparation, control - 28.7 thousand m2/ha. The highest productivity of Pannonian clover was obtained when seeds were inoculated with the biological product Gumariz together with the NanoSilicon preparation: dry matter - 12.48 t/ha, feed units - 9.05 t/ha, digestible protein - 1.39 t/ha; the yield of clover seeds was 786.8 kg/ha, which is 2.2 times higher than the control indicators; profitability for cultivation for seeds - 187.3%, for fodder purposes - 149.6%, energy efficiency coefficient - 2.24 and 1.89 units.
