ENVIRONMENTALLY SAFE APPROACHES TO SUNFLOWER CULTIVATION

Abstract

Thus, the application of biopreparations (Ekostern Lite, Ekostern Classic, Ekostern Bacterial) compared to the control variant without the destructor shows significantly higher decomposition rates of plant residues. Of the three preparations studied, Ekostern Bacterial gave the best results (66.8% versus 53.2% in control), with the difference according to LSD₀₅ (4.8–6.1%, depending on the year) confirming the statistical reliability of the data. The correlation-regression model we constructed confirmed a strong relationship between the decomposition intensity of winter wheat stubble after the application of decomposers in sunflower crops and the increase in grain yield (according to the Chaddock scale, the coefficient of determination indicates a very high degree of correlation). This makes it possible to recommend using decomposers to activate the decomposition of plant residues, improve the soil nutrient status, and increase the yield of crops.
