The effect of innovative copper-zinc chelate fertilizer on rice-plant growth and development in vegetation experience

Abstract

The work studied the effect of various concentrations of an innovative zinc-copper chelate compound on rice plants as a microfertilizer, which was invented at the Kuban State Agrarian University named after I.T. Trubilin. The effect of foliar feeding of plants and pre-sowing treatment of seeds with the studied microfertilizer on the growth and development of rice plants in laboratory and vegetation experiments was studied. The toxic effect of copper-zinc chelated fertilizer was revealed at its concentration above 0.05%. It was found that when processing rice seeds with 0.001%, 0.005% and 0.01% solutions of microelements, their germination energy increased by 6.8%, 8.2% and 6.8%, respectively, laboratory germination under these conditions reached 97.0%, 96.0% and 98.8%, respectively, which exceeded the control option by 3.2%, 2.1% and 5.1%.
