Environmental Aspects of Sustainable Corn Production and its Impact on Grain Quality

In recent years the question about organic cultivation of crops is becoming more popular. It means, that farmers which want to use organic products and grow crops it sustainable way have to follow certain rules. So, the aim of our study was to estimate effect of seed inoculation and foliar fertilization of corn by special fertilizer products with microorganisms that certified Organic standard. Therefore, corn seeds were treated by biofertilizers in liquid (Leanum) and powdered (Vitamin O7) forms and then sown in the field conditions. During summer period, plants were treated by liquid fertilizer one or two times. Also, impact of the soil tillage was studied. Research was conducted on the effects of cultivation at depths of 15–18 and 5–8 cm, as well as plowing and flat–cutting cultivation at depths of 25–28 cm. It was found that fertilization impacted on corn yield and grain quality – protein, ash and starch content. Usage of seed inoculants and foliar fertilization in generally leads to increase yield but at different levels. Protein and oil content had a weak positive correlation with applied fertilizers on the background of flat–cut tillage.
