The article investigates complex application of pesticides, microelements, growth regulators Ecosil for pre-sowing seed treatment and foliar top dressing of clover hybrid. It is found how these components enhance seed herbage structure and seed productivity. Microelements (boric acid, molybdenum-ammonium, Maxibor 21) for foliar top dressing in various phases provide maximal clover productivity of 2.74 -3.0 centner per ha. Seed productivity growth by 0.8-0.95 centner per ha (32-44 %) was obtained due to various intensification agents
