Abstract:
The biochar amendment in soil had got more attention of research in the recent time, to reclaim acidic soil. The aim of this study was to increase yield of red beet and cabbage in pot experiment via biochar for the experiments were pyrolysis by 500oC and sieved with mesh size 2mm applied in acidic soil with pH= 4.98 at the rate of six different treatments. The results of the study showed a significant (P<0.05) increase in dry weight of red beet 7.16±0.03 g at highest application of biochar comparing to control soil 1.325±0.009 g similarly 5.32±0.2 g of cabbage was obtained highest application of biochar combined with fertilizer comparing to control soil 0.94±0.03g. A significant (P <0.05) result in soil pH 7.83±0.001 and 7.97±0.02 increased with significantly comparing to control soil pH 4.83±0.08 and 4.74±0.12 after harvesting of cabbage and red beet. The EC 0.30±0.0007mScm_1 was obtained from application of highest does of biochar at red beet comparing to control soil EC= 0.11±0.003 and EC=0.28±0.015 m s/cm also obtained at cabbage comparing to control soil 0.11±0.003 mScm_1. Particularly soil organic carbon 1.98±0.09 and 2.22±0.023 % were obtained from the high dose of biochar after harvest of red beet and cabbage respectively which, showed trends of increase with increasing biochar application compared to the control soil 0.74 % value for the two crops. A significantly CEC difference (at p < 0.05) was observed between treatments (48.42±0.07 cmolc kg-1) and control (17.81±0.04 cmolc kg-1) on cabbage. similarly significant (P<0.05 increasing of CEC 36.4±4.324 cmol (+) kg soil application of highest treatments of biochar together with fertilizer comparing to control soil 17.81±0.060 cmol (+) kg soil on red beet The total nitrogen 0.23±0.01 and 0.25±0.01 % was obtained highest biochar nested on fertilization compared to the control 0.16 and 0.15% after harvest red beet and cabbage respectively.Therefore, application biochar is very imperative to increase soil fertility, enhance nutrient retention and remediate acidic soil.
