Abstract:
A field experiment was conducted during kharif and rabi seasons of 2018-19 to evaluate the impact of conservation agricultural management practices on carbon sequestration potential through soybean-chickpea cropping system in different villages of Barshi Takali tahsil, Akola District in Maharashtra. The results of study showed that carbon input in kharif through leaf litter biomass and stubble biomass was noted significantly higher (2.27 Mg ha^-1) under conservation tillage for 15 years which is followed by treatment T5 (2.22 Mg ha^-1) and T6 (2.16 Mg ha^-1) under conservation tillage done for 12 and 10 years respectively. The highest (3.23 Mg ha-1) total carbon input through leaf litter biomass and stubble biomass of Soybean-Chickpea cropping system was recorded under conservation tillage for 15 years and the lowest (2.36 Mg ha-1) was observed under conventional tillage during 2018-19. By adoption of conservation tillage practices along with residue retention of leaf litter biomass and stubble biomass total carbon input addition was increased by 36.86 per cent over conventional tillage. Hence, the consistent adoption of conservation agricultural management practices along with residue management improves the total carbon input and carbon sequestration potential under conservation agricultural system.
