A pot experiment was conducted to investigate the potential of using tomato stems biochar (TSB) prepared at three pyrolysis temperatures (250°C, 400°C, and 600°C) as an agricultural enhancer in sandy soil to improve quality indicators, nitrogen use efficiency (NUE), and wheat growth. This experiment included the following treatments; control (no biochar added), 1% TSB250, 2.5% TSB250, 5% TSB250, 1% TSB400, 2.5% TSB400, 5% TSB400, 1% TSB600, 2.5% TSB600, and 5% TSB6000, where every type of biochar was applied at different doses (1, 2.5, and 5% w/w). The experiment was designed in a completely randomized design with three replications. Compared to the unamended soil, applying TSB250 decreased significantly soil pH from 8.25 for Control to 8.17, 7.73, and 7.62 for levels 1%, 2.5%, and 5% respectively, while the applications of TSB400, and TSB600 significantly increased soil pH. Applying TSB caused increased soil available nitrogen by 28%, 9.60%, 27.40%, 45%, and 8.70% for the TSB600 at 1, 2.5%, and TSB400 at all levels, respectively. Available nitrogen in sandy soil decreased significantly with TSB250 addition at doses of 2.5%, and 5%. Fresh and dry biomass of wheat increased significantly with the application of tomato stems biochar. Adding TSB400 and TSB600 at all doses as well as 1% TSB250 into sandy soil led to significant increases in NUE of wheat. The effectiveness of tomato stems biochar treatments on NUE increased in the order of TSB400 > TSB600 > TSB250. Based on these results, we recommend applying TSB400 at 2.5% to sandy soils.
