Background and Objective: This study was conducted to evaluate the effects of sulfur fertilizer and Acidithiobacillus levels on potato tuber yield and some soil nutrients.
Materials and Methods: The experiment was conducted as a factorial based on randomized complete block design with three replications in 2019. The experimental factors included sulfur fertilizer levels (0, 300, 600, 900 and 1200 kg.ha-1) and Acidithiobacillus bacteria levels (inoculation and non-inoculation).
Results: The effect of sulfur fertilizer and Acidithiobacillus application were significant on potato tuber and biological yield. The highest amount of tuber yield was obtained from using Acidithiobacillus, and the lowest amount belonged to not using Acidithiobacillus. The highest amount of tuber yield was related to the treatment of 1200 kilograms of sulfur. Application of sulfur fertilizer and Acidithiobacillus decreased the nitrate residue in potatoes. Using sulfur fertilizer and Acidithiobacillus lowered the soil pH and the highest soil pH was obtained in the control conditions (no use of sulfur and Acidithiobacillus). The highest amount of starch and tuber dry matter were obtained in the treatment of 1200 kg.ha-1 of sulfur fertilizer.
Conclusion
The results showed that the use of sulfur and Acidithiobacillus along with using basic chemical fertilizers was evaluated positively on the yield and some quality traits of potato as well as some chemical properties of the soil. Using Acidithiobacillus and sulfur decreased the pH of the soil. In general, the use of 1200 Kg.ha-1 sulfur fertilizer together with Acidithiobacillus bacteria is recommended to increase the quantity and quality of potatoes.
