Abstract
This study was conducted to evaluate the effect of rice cover crop cropping systems on rice root growth in a rice field as affected by conventional tillage without rice straw or green manure crop treatment (CTFS, check plot), no-tillage without cover crops (NTNT), no-tillage amended with rape (NTRA), no-tillage amended with rye (NTRY), no-tillage amended with hairyvetch (NTHV), and no-tillage amended with Chinese milk vetch (NTCM). In 0-5 cm soil depth, dry weight of root in NTRS ($128g\;m^{-2}$) was significantly higher than in the other plots (p<0.05) at harvesting stage. In addition, content of active organic matter at 0-5 cm soil depth was $1,684g\;m^{-2}$ in NTCM, $1,309g\;m^{-2}$ in NTRA, $1,295g\;m^{-2}$ in NTRS, $1,072g\;m^{-2}$ in NTRY, $917g\;m^{-2}$ in NTHV, $434g\;m^{-2}$ CTFS, and $426g\;m^{-2}$ in NTNT treatment. In no-tillage rice cover crop cropping system, our findings suggest that NTRS and NTCM should be enhanced root growth and active organic matter in paddy field.
