The article discusses the use of domestic liquid bio-organic fertilizer "BioEcoGum" in the cultivation of corn and soybeans in the south-east of Kazakhstan. The influence of seed treatment and foliar top dressing during the growing season on the growth, development and yield of corn (Porumben 458) and soybeans (Zhansaya, Victory) was studied. Pre-sowing treatment of corn and soybean seeds with a solution of liquid bioorganic fertilizer increases germination by 10-15 %. Two and three-fold foliar top dressing of corn and soybean plants enhances growth and development, increases the yield of soybean grain by 25-33 % and corn by 75 %, contributes to an increase in root biomass by 50 %, increases the economic efficiency of application. According to the results of production tests, the bio-organic liquid fertilizer "BioEcoGum" is recommended for widespread introduction in the south and south-east of Kazakhstan in the cultivation of grain and leguminous crops.
