The Effect of Biofertilization on Potato Yield Components

The potatoes (Solanum tuberosum L.) are the third most important food crop in Bosnia and Herzegovina, right after maize and wheat. It was grown on an area of 39,051 ha with an average yield of 11.3 t ha−1 in 2020. The potato root system is shallow, with a poor ability to extract nutrients from the soil. Therefore, potatoes should be provided with enough nutrients during cultivation to achieve high yields. This work aimed to examine the impact of biofertilizers on potato yield in the environment of central Bosnia and Herzegovina. The treatments used in this research consisted of several different fertilizers (mineral fertilizer, mineral fertilizer + biofertilizer, organic fertilizer and organic fertilizer + biofertilizer). The Carrera variety was used in the research. The research results showed that biofertilizer increased the number of tubers per plant. Biofertilizer variants had more tubers per plant (7.12) than those without it (6.93). The range of tuber mass was between 115.80 g (organic fertilizer) to 134.91 g. (mineral fertilizer). Depending on the year of research, potato yield ranged from 34.83 t ha−1 (2018) to 37.51 t ha−1 (2019). The applied fertilizers did not significantly affect the content of dry matter in the potato tuber.
