New rice technology - short duration varieties, herbicides, and tillage machinery with higher horsepower - may make new systems of land preparation and crop establishment economically feasible. To identify conditions for adaption of alternative systems and to determine where further research is necessary, the characteristics of the traditional rainfed rice land preparation transplanting system and its alternative are reviewed. The major advantages of wetland tillage are reduction of draft requirements, improved weed control, ease of transplanting, enhancement of soil fertility, and reduction of percolation losses. The major disadvantages of wetland tillage are increased late-season drought risk, high transplanting labor requirements and power unit sizelimitations. Once the soil has been puddled, the method of crop establishment is restricted to transplanting or direct seeding of pregerminated seeds... |
