Water is the major limiting factor for crop production. A lot of water resources have been exploited for irrigation purpose. Therefore, the objective of this review paper was to collect information on cabbage water requirement, irrigation scheduling and water use efficiency by triangulating different literatures on the topic. Nowadays on worldwide there is a water-shortage, accordingly it is necessary to adopt water saving agriculture as a counter measure as well as efficient use of irrigation water is becoming increasingly important. In growing crop, irrigation scheduling is a critical management input to ensure optimum soil moisture status for proper plant growth and development as well as for optimum yield, water use efficiency and economic benefits. Thus according reviewed literatures on average twice a week irrigation scheduling and 2.57 - 5.81 mm/day of crop water requirement is more visible for cabbage production. In addition, climate models were reviewed in detail in this paper CROPWAT 8.0 and DSSAT reproduce acceptably the unimodal and bimodal shapes of the annual variation of rainfall and temperature respectively; there is a time shift between the observed and simulated peaks. Therefore it is essential to develop irrigation scheduling strategies under local climatic conditions to utilize scarce water resources efficiently and effectively for crop production.
