Comparison of different biochar and fertilizer levels on yield and yield components of wheat and water use efficiency

The biochar produced from organic matter and agricultural residues is a soil amendment that can increase porosity, decrease bulk density and increase moisture content in the soil. In this study, the effects of different levels of 1.5 and 3.5 by weight percent of biochar produced from wheat straw and 1.5 and 3 by weight percent of fertilizers on wheat yield and soil characteristics were investigated. Water use efficiency and water consumption were also studied. The results showed that the highest average dry weight of wheat was 3% (B2) with 2.69 and the lowest was 1.05% by weight (2.22 g / plant). The average volume of moisture content in treatment B2 was 29.36% higher than other treatments, and the addition of biochar to soil increased the electrical conductivity related to fertilizer and control treatment. The highest mean water use efficiency in dry weight of wheat was related to B2 treatment with 2.87 g / liter, indicating a significant difference of 5% of the treatment with control and 1.5% fertilizer.
