The study looked at how different types of fertilizers can increase potato yield. By using organic and microelement fertilizers, the researchers found a 39.6% increase in yield and a 21% increase in marketable tubers compared to compound fertilizer alone. Organic fertilizer combined with microbial fertilizer showed the most significant increase in yield and marketable tubers. The increase in yield varied depending on the soil type, with a 10.9% increase in black clay soil and a 32.0% increase in alluvial soil.
