Rationalization of water consumption Water Conservation

Water consumption or (WU) 1) Water use in plants 2) Water use in Evaporation 3) Water use in Transpiration Factors effecting WU 1) Climatic factors 2) Plant factors 3) Soil factors

Water conservation methods (Rationalization) Genetic methods Selection for drought resistance Selection for water use efficiency ( WUE)

4) Using of suitable irrigation system 2) Agronomic methods - Selection of suitable sowing date - Selection of suitable sowing rate -Suitable and good fertilization - Weeds and pests resistance 3) Using of sewage water 4) Using of suitable irrigation system

- Traditional methods 5) Using of suitable irrigation scheduling - Based on interval time - Scientific methods 1) Based on mathematical equations 2) Using crop water stress index(CWSI) 3) Using Cumulative evaporation pan (CPE)

6) Introducing new crops with low water needs drought-resistant Short growing season 7) Using Magnetic Technologies in Correction of irrigation water salinity
