Introduction

In on going many years, water asset supervisors have confronted troubles in fulfilling the numerous and always developing water requests of semi-parched regions. This is especially evident in the Mediterranean bowl, where an expansion in water system grounds and force has been joined by a diminishing in accessible water assets because of segment development and simultaneousness with improvement related exercises. Since horticulture is the significant water client, its effective use is expected to ration this restricted asset. To support horticultural creation, a more objective farming water use is required, especially in regions where the flow water system frameworks and practices are exceptionally wasteful. Water system the executives is an appealing an open door to mitigate water shortage in the Mediterranean bowl, since the procedure requires no new framework. Potato rates fourth among the world's farming items as far as creation volume, after wheat rice and corn It is a mild harvest, developing and yielding great in cool and damp environments or seasons, however it is likewise developed in tropical to sub-polar climatic districts, and addresses a significant food crop in numerous nations. Among the numerous ecological elements influencing yield, water supply is a significant restricting variable in the creation and nature of potatoes. The potato is known to be delicate to water deficiency. To get exceptional returns, the dirt water content ought to be no lower than half of most extreme accessible water in the root zone, particularly during tuber development even slight water pressure causes a decrease in number of leaves, leaf size, covering radiation capture and photosynthesis, and thus influences the number, size and the level of attractive tubers [1-3].

In the Mediterranean Bowl, potato creation possesses a general area of around 1 million ha and produces 28 million t of tubers (FAO, 2010). In a few nations, for example, Tunisia, Egypt, Cyprus, Israel, Lebanon, Turkey and southern Italy, potatoes are developed in the standard cycle (springsummer) yet in addition in the colder time of year spring cycle (planting from November to January and collecting from spring to early September) for early creation. Early potatoes, characterized as "potatoes collected before they are totally adult, promoted following gathering and whose skin can be effortlessly eliminated without stripping" (Joined Countries Financial Commission for Europe of Geneva, New Leafy foods 30/2001), are exceptionally valued and basically sent out to northern European nations, with impressive benefit.

Potatoes developed for early creation are likewise especially delicate to water pressure, which unfavourably impacts tuber yield as well as earliness In the Mediterranean seaside districts, water system is principal for high early potato yield. For sure, the yield is planted during cold weather months when precipitation generally surpasses dissipation, yet in the progressive phases of development of the flying part and of tubers from the finish of winter to the entire of spring, the precipitation diminishes while evapotranspiration and temperatures increment, consequently causing significant soil water deficiencies. Accordingly, early potato development in this area typically falls back on water system all through the spring, harmonizing with the period of tuber building and development. In any case, water the board inside the Mediterranean locale is completed observationally and is in this manner portrayed by a specific fluctuation corresponding to how much precipitation, its dispersion and the pressure driven qualities of the dirt [4,5].

Conclusion

Where water system is utilized methodically, how much water provided, the quantity of watering’s and timing between watering’s might vary starting with one season then onto the next, generally speaking, generally half of harvest water prerequisites are fulfilled by water system and the leftover by precipitation; in any case, exorbitant water inputs (up to 250-300 mm for each yield season) disseminated by upwards of 15 watering’s are likewise normal because of wasteful water system strategies (wrinkle, full scale sprinklers). For best yields, a sufficient stock of water is expected consistently however dampness stress during tuber inception and building periods lessens yields more than at some other period.
