Demirbaş, et al (2024) Effects of Different Doses of Biochar Applications on Yield and Nutrient Element Concentrations on Wheat Grown under Salt Stress. Cumhuriyet Science Journal. https://doi.org/10.17776/csj.1500231


A study published in Cumhuriyet Science Journal examines how different doses of biochar affect wheat yield and nutrient absorption under salt stress. Conducted in a controlled greenhouse environment, the experiment involved varying salt concentrations (0, 6, and 12 dS m⁻¹) and biochar levels (0%, 0.5%, 1%, and 2% by weight). Biochar was derived from peanut shells through slow pyrolysis.

The results indicated that biochar applications generally increased dry matter yield, with the highest yield of 1.85 g/pot achieved using a 2% biochar application at moderate salinity (6 dS m⁻¹). However, at higher salinity (12 dS m⁻¹), biochar’s positive effect diminished, and yield reductions were observed.

Nutrient uptake was also influenced by biochar and salinity levels. While biochar applications increased the concentrations of micronutrients such as iron (Fe), zinc (Zn), manganese (Mn), and copper (Cu) at all salt levels compared to controls, overall nutrient concentrations declined as salinity increased. This suggests that while biochar can boost nutrient availability, its benefits are limited in highly saline conditions.

In conclusion, biochar can mitigate some effects of moderate salt stress on wheat, enhancing growth and nutrient uptake. However, its efficacy decreases as salt levels rise, highlighting the challenges of growing wheat in severely saline soils. Further research may explore optimizing biochar use for different crop and stress conditions.
