A pot experiment was conducted in a wired greenhouse under local weather conditions at the Faculty of Technology & Development greenhouses, Zagazig University, Zagazig, Egypt. Maize plants were used as an indicator for the examination of produced bagasse biochar effects on soil properties and maize plants growth in sandy soil. Bagasse biochar was mixed with soil in rates of 0, 1, 2.5, 5, 10% and randomized complete–plot design with three replicates. Forty days after sowing, maize plants were estimated for chlorophyll content, root depth, plant height. Some soil properties such as particles density (PD), bulk density (BD), water–holding capacity (WHC), soil porosity, organic matter (OM), electrical conductivity (EC) and pH were determined. Maize plants were dried, milled and analyzed for N, P, K and Si. The obtained results indicated to that application of bagasse biochar significantly improved soil physio–chemical properties such as PD, BD, porosity, WHC, OM and maize N, P, K and Si contents. Also, biochar led to improving maize plants growth, chlorophyll content, roots depth and maize height. Conclusively, it can be concluded that the use of bagasse biochar in amending sandy soil caused a significant increase in maize plants growth and available nutrients uptake.
