Abstract: Background and Objective: Wheat stalks residual is the important problem which faces both planting and germination of rice seeds. So, wheat stalks must be burnt before soil tillage. The aim of this study was the development and evaluation of a-unit for burning wheat stalks residual before soil tillage. Materials and Mathods: To achieve that aim 3 operating parameters were used in sub-sub plot design, 4 forward speeds (3.19, 3.97, 4.5 and 5.4 km h1), 3 distance between flame cannon (30, 40 and 50 cm) and 3 flame cannon height from soil (10, 15 and 20 cm) with 3 replicates. The obtained data in this study was analyzed with the statistical analysis software CoStat (version 6.4) in one way completely randomized design. Duncans multiple range test was used to compare the means at probability level of 0.05. Results: The obtained results show that, the maximum burning efficiency and gas consumption were 95.86% and 4.15 (kg fed1), respectively at forward speed (3.19 km h1), flame height from soil 10 and 30 cm distance between flame cannon. Fungal population of all genera decreased in the 1st speed and 3rd h after treating compared with control. This study gave good results when use temperature to control soil-borne pathogens. Conclusion: It was concluded a simple flame unit fitted on a chisel plow was developed, tested and evaluated. Using the flame to control the pests can reduce the chemical applications that increase environmental pollution. This treatment could be applied to control soil pests once every year.
