The Mineral Biochar Alters the Biochemical and Microbial Properties of the Soil and the Grain Yield of Hordeum vulgare L. under Drought Stress

Biochar improves soil physical, biochemical, and microbial properties, leading to the amelioration of fertility, which, in turn, results better growth yield crop plants. The current study aimed evaluate whether using different levels biochar can enhance characteristics plant attributes. Accordingly, an experimental was conducted 2022 a randomized complete block design with four replications (n = 4) glasshouse University Zanjan, which two regimes irrigation (D0, full as control; D1, water scarcity applied immediately after flowering stage for weeks) natural mineral (0% control treatment, 0.25, 0.5, 1% weight) were applied. indicated that drought substantially decreased organic carbon content grain while increasing available phosphorous, carbohydrate content, biomass soil. could considerably alter means studied quality parameters barley yield. Adding be considered valid strategy increase resistance plants drought.
