Carbon Dioxide Equivalent Carbon Stock under Wheat and Eucalyptus Based Agroforestry System in Central India

Abstract

An experiment was organised to evaluation of carbon dioxide equivalent carbon stock or sequestration by wheat, weed and eucalyptus tree under an agroforestry system with different weed control treatments. The two year experiment was performed during 2016-17 and 2017-18 in a well managed farmer field of block shahpura village majitha, Jabalpur with supervision of department of forestry jnkvv Jabalpur. The result revealed that the wheat crop found total CO2 equivalent C stock was significantly higher under hand weeding at 30 DAS 15.62 and 14.07 t/ha during 2016-17 and 2017-18, respectivelyover weedy check.The pooled data in wheat crop showed thatweed management practices was found higher total CO2 equivalent C stock range from (10.87 to 14.85 t/ha) over weedy check (9.68 t/ha) under wheat-Eucalyptus tereticornis based agroforestry system.The total CO2 equivalent C stockin weed was significantly higher under weedy check (4.31 to 4.37 t/ha during 2016-17 and 2017-18, respectively) over hand weeding at 30 DAS (0.57 and 0.18 t/ha during both year). The pooled data showed that the average total CO2 equivalent C stock in weed was significantly higher under weedy check (4.34 t/ha) over hand weeding 30 DAS (0.30 t/ha). The weed management practices was found lower CO2 equivalent C stockrange from (0.38 to 1.80 t/ha) under a wheat-Eucalyptus tereticornis based agroforestry system. The total CO2 equivalent C stock of eucalyptus tree was found range between 195.11 to 204.61 t/ha and 248.39 to 258.78 t/ha was found during during 2016-17 and 2017-18, respectively under wheat-Eucalyptus tereticornis based agroforestry system.The statistical analysis of the pooled data showed that the CO2 equivalent C stockin eucalyptus tree varied from 224.18 to 230.86 t/ha was found under wheat-Eucalyptus tereticornis based agroforestry system.CO2 equivalent C stockof agroforestry system was found to range between 63.06 to 66.93 t/ha and 62.48 to 66.01 t/ha during 2016-17 and 2017-18 under wheat-Eucalyptus tereticornis based agroforestry system.The pooled data showed that total CO2 equivalent C stockin agroforestry system was found varied from 62.77 to 66.47 t/ha under wheat-Eucalyptus tereticornis based agroforestry system.
