Figure 2. Increase in soil organic carbon (%) assuming 100% for TPR followed by conventional tilled wheat influenced by conservation and conventional practice and contrast of upper depths between different practices at Rampur, Chitwan Nepal from 2011/12-2012/13. Treatment means followed by common letter(s) in the column are not significantly different among each other based on DMRT at 0.05. NS= non significant. CTDSR+ ZTW= Conventional tilled dry direct seed Rice followed by Zero tilled wheat. TPR+CTDSW= Transplanted rice followed by conventional tilled wheat. ZTR-ZTW+RH= Zero tilled rice followed by wheat without residue retention. ZTR-ZTW+RR= Zero tilled rice followed by wheat with residue retention. BPR-BPW+RH= permanent raised bed rice followed by wheat without residue retention. BPR-BPW+RR= permanent raised bed rice followed by wheat without residue retention with residue retention
