Rice is considered one of the most important foods and export to many countries.
Background
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. [email protected]

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 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.

Research Approach and Methodology
Research Approach and Methodology
The new technique of ricecultivation depends ontransplanting rice in thebottom of long furrows(trench) have a crosssection (V shape), by thistechnique the rice didn'texpose to water stress andthe volume of water willbecome less to about 50%of total soil size.

The innovative machine of soil and water management for rice (SWMR).
SWMR Machine isManufactured of acylinder rule (printer onsoil surface) having manyof circular teeth aroundthe basic cylinder rule toroll after subsoil chisel ofdepth 25 cm under the soilsurface, behind the tractoron soil and printed thedesigned V shape of crosssection of furrows.
Research Approach and Methodology
Rice is transplanted untwo methods (Traditional& SWMR), the nutrientsare applied inrecommendation dosesunder traditional methodand applied in threeamounts under SWMRmethod (50%, 75% and100% of recommendedrequirements.

Future SMWR developmentThe type A is saved about 47% of irrigation water, thetype B replaces more soilinstead of water accordingto the reduce the V shape,angle, and also type C have alower angel and the largestreplaced soil and expectedsave more water andnutrients.
Isometric design showsthe type A, B and C vs.The traditional method ofrice planting.
