Management of applied practices in the field such as, water quality, irrigation amount,
fertilizer use, and soil tillage etc. has considerably impact on the amount of CO2 emissions in
agricultural systems. The principal objective of this research was to discover how CO2 emissions
respond to water quality and amount under different soil tillage practices. For this aim two years field
experiment was carried out under no-tillage (NT) and conventional tillage (CT) practices on silage
maize with wastewater irrigation at different water levels (WW100%, WW67% and WW33%) and
freshwater irrigation (FW100%) as control treatment. The results revealed that the interaction of
irrigation and tillage practices was statistically significant at all measurement time intervals. CT
increased CO2 emission as compared to NT under all irrigation treatments. Irrigation with wastewater
increased CO2 emission as compared to freshwater irrigation in both NT and CT. In both soil tillage
treatments, the measured CO2 emissions from WW100% and WW67% were higher as compared to
FW100% whereas WW33% treatment released less CO2 than FW100%. Our results showed that with
different scenarios depending on the amount and quality of available water and soil tillage practices,
different solutions could be applied to improve climate resilience for a given region.
