Abstract
Reduced tillage is widely used among conservation tillage treatments thanks to its reduced field traffic and lower fuel consumption. The fact that this method causes less CO2 emission when compared to conventional tillage makes reduced tillage prominent in terms of environment and sustainability of soil resources. This study analyzed the effects of conventional and reduced tillage on CO2 emission throughout wheat production period. In conventional tillage (moldboard plough-cultivator + rotary harrow combination), two horizontal axis rotary tiller and one vertical axis rotary tiller were used. After tillage applications, mean weight diameter of soil, penetration resistance, stubble burying ratio, CO2 emission after tillage varied between 9.54-6.53 mm, 0.91-1.32 MPa, 52.78% - 70.37,0.42-0.84 gm-2h-1 respectively. Total CO2 emission of each treatment in the period from tillage to harvest varied between 2149-2301 kg/da. Analysis of variance on total emission values showed that the difference between the treatments was significant (P<0.01). There was a significant relationship between penetration resistance of soil, tillage depth, and CO2 emission (P<0.01). Analysis of the treatments in terms of CO2 emission revealed that machine with horizontal axis I type tilling foot was more appropriate.
