Shortages of water and the rapid spread of two-wheel tractors (2WT) have created the opportunity to develop locally-adapted conservation agriculture (CA) techniques for crop establishment by rice-based smallholders in South Asia. During 2009, the wet season rice (Oryza sativa L.) was transplanted into minimum tillage puddled; unpuddled-bed and strip tillage conditions in the drought-prone area of Bangladesh, to assess establishment methods that could reduce crop production cost and water use. Land preparations were done by the 2-WT operated, Versatile Multi-crop Planter (VMP) recently developed by CIMMYT, Bangladesh. Tillage treatments did not influence the shoot dry matter production. There was 65 % less diesel fuel required in the strip tillage treatment than with beds formed by VMP. Labour requirement for land preparation in beds formed by a shaper were 4.5 times higher than single pass puddling and beds formed by VMP. Time required to transplant seedlings was almost doubled in unpuddled plots relative to puddled plots. Weeding cost was higher in beds formed by VMP and strip tillage plots compared to other tillage treatments. Regardless of tillage treatment, 41-43 % less irrigation water was used by crops established by VMP planting operations as compared to a traditional tillage system.
