Determination of the Effect of Biochar Applications on Soil Physical and Chemical Properties and Wheat ( Triticum aestivum L.) Germination and Biomass

In this study, in order to determine the effects of biochar applications on the physical and chemical properties of soils grown in Kayra bread wheat variety, this study was carried out in the form of a pot experiment in a randomized plot design with three replications and at five different doses 0 (B0), 10 (B1), 20 (B2), 40 (B3) and 80 (B4) t ha -1 biochar were applied. According to biochar applications, the highest pH, EC, lime, organic matter, total N, available P, K, Ca, Mg, Na, Zn, Fe, Mn, Cu and B values in the soil are 7.66, 2.26 mS cm -1 , 3.55%, 2.81%, 0.201%, 48.89 mg kg -1 , 1172.89 mg kg -1 , 2268.88 mg kg -1 , 186.92 mg kg -1 , 101.43 mg kg -1 , 2.34 mg kg -1 , 2.40 mg kg -1 , 7.33 mg kg -1 , 1.79 mg kg -1 and 1.08 mg kg -1 respectivelythe highest values were determined in B4 (80 t ha -1 ) application. The lowest values in soil according to biochar applications were pH, EC, lime, organic matter, total N, the available P, K, Ca, Mg, Na, Zn, Fe, Mn, Cu and B values are 7.45, 0.87 mS cm -1 , 2.28%, 1.28%, 0.078%, 14.92 mg kg -1 , 344.84 mg kg -1 2171.68 mg kg -1 , 129.01 mg kg -1 , 47.09 mg kg -1 , 1.25 mg kg -1 , 1.82 mg kg -1 , 4.52 mg kg -1 , 1.61 mg kg -1 and 0.71 mg kg -1 detected in B0 (control) application. The highest germination rate in wheat seeds was found in B2 with 95.41% and the lowest germination rate was found in B0 applications with 90.12%. It was determined that the effects of biochar applications on the fresh and dry weight of the plant were the highest in B2 application (11.42 and 2.21 gr pot -1 ) and the lowest values in B0 application (10.01 and 1.93 gr pot -1 ), respectively. It was detected in 09 mg kg -1 , 1.25 mg kg -1 , 1.82 mg kg -1 , 4.52 mg kg -1 , 1.61 mg kg -1 and 0.71 mg kg -1 B0 (control) application. The highest germination rate in wheat seeds was found in B2 with 95.41% and the lowest germination rate was found in B0 applications with 90.12%. It was determined that the effects of biochar applications on the fresh and dry weight of the plant were the highest in B2 application (11.42 and 2.21 gr pot -1 ) and the lowest values in B0 application (10.01 and 1.93 gr pot -1 ), respectively. It was detected in 09 mg kg -1 , 1.25 mg kg -1 , 1.82 mg kg -1 , 4.52 mg kg -1 , 1.61 mg kg -1 and 0.71 mg kg -1 B0 (control) application. The highest germination rate in wheat seeds was found in B2 with 95.41% and the lowest germination rate was found in B0 applications with 90.12%. It was determined that the effects of biochar applications on the fresh and dry weight of the plant were the highest in B2 application (11.42 and 2.21 gr pot -1) and the lowest values in B0 application (10.01 and 1.93 gr pot-1), respectively.
