Abstract

The potential of biochar has increased interest in recent decades due to the increasing agricultural yield and nutritional value of products. However, scarce data have been published about the impact of biochar on the nutritional quality of products. Therefore, in this study, we assess the effects of biochar on plant health and productivity with different percentages (%) of the biochar e.g., 0%, 30%, 50%, and 70%. The gas chromatography (GC) analysis of M. arvensis treated with different concentrations of biochar showed different arrays of compounds, especially 33 compounds found in 30% biochar with an abundant source of 2-Propyl-5-acetoxy-5-methyltetrahydropyran, p-Menthan-3-one, 1,2-epoxy, and 2-Hydroxyhexadecyl butanoate. Similarly, the physicochemical characteristics of the plants showed that 30% of biochar application significantly (p > 0.05) improved the plant growth attributes e.g., shoot and root length, and fresh and dry biomass. The electrical conductivity (EC), pH, phosphorous, nitrogen, and organic compounds were also significantly (p > 0.05) improved with the addition of biochar in the soil and compared to only soil. The nutrient profiling showed that the biochar treatment significantly improved Ca, Mg, Na, and Ni compared to the soil. Antioxidant enzymes (CAT, GST, POX, and SOD) in plant and antioxidant activity of plant extracts such as DPPH, superoxide, Hydroxyl radical scavenging, TPC, and FTC were significantly improved by 30% biochar compared to control as well as 50, and 70% of biochar. The overall conclusion showed that 30% biochar application in the soil improved the valuable compounds in the soil and enhanced nutrients and antioxidant activities in M. arvensis, which improved the growth and development of plants.
