Save Irrigation Water and Nutrients Using the Innovative Machine of Soil and Water Management for Rice Crop Cultivation (SWMR) 

  1. 1. Save Irrigation Water and Nutrients Using the Innovative Machine of Soil and Water Management for Rice Crop Cultivation (SWMR) Dr. MOHAMED ELHAGAREY DESERT RESEARCH CENTER, CAIRO, EGYPT
  2. 2. Rice is considered one of the most important foods and export to many countries.
  3. 3. Rice is a global strategic crop Irrigated rice receives an estimated about 40 % of the total world’s irrigation water, Rice is the second crop of yield amount and the third crop of the cultivated area in the world, Rice is the food for about half world people.
  4. 4. Traditional methods cause a water and nutrient losses
  5. 5. Objectives: The main objectives of the Innovation of Soil and Water Management machine for Rice Cultivation (SWMR) are: 1) Development of SWMR design to be more flexible in various soil textures. 2) Resulting of the modified SWMR type to produce the mass product. 3) Maximizing the WUE and FUE of rice crop. 4) Minimizing of rice water footprints. 5) Applicability and spreading of a modern rice cultivation method to save water. 6) Reduction of water and nutrient losses by exceeding irrigation of paddy. 7) Change of rice cultivation map according to new innovative method. 8) Provide a new reclamation land using surplus water.
  6. 6. The new technique of rice cultivation depends on transplanting rice in the bottom of long furrows (trench) have a cross section (V shape), by this technique the rice didn't expose to water stress and the volume of water will become less to about 50% of total basin size.
  7. 7. The new technique of rice cultivation depends on transplanting rice in the bottom of a long trench have a cross section V shape
  8. 8. SWMR Machine is Manufactured of a cylinder rule (printer on soil surface) having many of circular teeth around the basic cylinder rule to roll after subsoil chisel of depth 25 cm under the soil surface, behind the tractor on soil and printed the designed V shape of cross section of furrows. The innovative machine of soil and water management for rice (SWMR).
  9. 9. Rice is transplanted un two methods (Traditional & SWMR), the nutrients are applied in recommendation doses under traditional method and applied in three amounts under SWMR method (50%, 75% and 100% of recommended requirements.

  15. 15. Future SMWR development The type A is saved about 47 % of irrigation water, the type B replaces more soil instead of water according to the reduce the V shape, angle, and also type C have a lower angel and the largest replaced soil and expected save more water and nutrients.
  16. 16. Isometric design shows the type A, B and C vs. The traditional method of rice planting.
