摘要：

Planting of rice transplant technology is ancient and practiced in all regions where the crop is grown, unfortunately consumes large volumes of water, because it remains throughout its cycle with water logging. Therefore, research in the Scientific Technological Base Unit "Palaces", aimed to assess the effect of suspending the sheet of water on crop yield of rice transplanting. This confidence intervals were used. At 30 days after transplantation 50 % of the experimental area was suspended the water surface for a period of 15 days, assessments were made and at the time of the harvest at the end of it As a result of water management agricultural output increased by 31,26 % and saved about 1 931,4 m(3).ha(-1) water. The saved water may increase the area under irrigation by 11,19 % for rice cultivation.
