Figure 1. Change in soil organic carbon as influenced by conservation and conventional practice at Rampur, Chitwan, Nepal, 2012/13. 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
