A field experiment was conducted with wheat to study the effect of tillage operations on the changes of the CO2- balance and reflection thereof, if any, on the yield of the crop. The organic sources in the form of decomposed paddy straw and farm yard manure (FYM) were applied in soil and the changes of the CO2-in and CO2-out were observed at the conventional (CT) and zero tillage (ZT) practices. The maximum level of CO2-in (914.06 ppm) and CO2-out (859.43 ppm) were recorded under the CT. The magnitude of yield differences of wheat was in the order of the treatment T9>T6 (where, T9; full dose of paddy straw and FYM and T6; half dose of paddy straw and full FYM). A close correlation was observed between the CO2- balance and ambient temperature at the proximity of the leaf surfaces corresponding to different treatments. The gradual decrease of CO2-out (ppm) was observed upto the day five (D5) when the maximum leaf – temperature was on day two (D2) under each treatment.
