Greece is the EU’s main cotton grower, accounting for more than 80 percent of total European production. About 79.700 producers are concentrated in Thessaly, Macedonia, Thrace, and Mainland Greece, the major cotton-producing areas. Cotton is essential for Greek agricultural production, accounting for more than nine percent of total agricultural output. Cotton in Greece is planted from March 1 to April 15, and the crop life cycle is usually 170 to 210 days, depending on the variety and weather conditions. The harvest typically occurs from October 1 to November 30; most cotton is machine harvested. Especially for Karditsa’s prefecture, cotton is the most important agricultural product. It covers an area of 40309 ha, when the area of all annual crops in the Prefecture is about 900000 str. (percentage 55%). Although farmers have cultivated cotton for many years, irrigation is a significant problem. The area under study is the Prefecture of Karditsa which is of particular interest because it is a part of the water district of Thessaly. This district consists of the most extensive plain of Greece and gathers all types of water consumption. It is an area where the occupations of most of the population are connected to the primary sector, which is confined almost exclusively to agriculture. For this reason, the resulting irrigation has an important role in both economic and social terms. Vouras, mentioned the critical significance of cotton growing in Greece. Karditsa's prefecture was one of the main areas, even in 1963. The increase in irrigation was one of the critical factors for the mass increase in cotton production (in addition to fertilizers, pesticides, and improved varieties of cotton. Evapotranspiration (ET) is an important component of the water cycle. It is composed of two subprocesses: evaporation from soil and vegetation surfaces and transpiration, which consists of the exchange of moisture between the plant and atmosphere through plant stomata. The importance of “evapotranspiration” (ET) in sustaining the global- and continental-scale “hydrologic cycle” and replenishing the world's “freshwater” resources have been recognized for thousands of years. The Blaney –Criddle method is a theoretical method to calculate the reference crop evapotranspiration. It is a simple method using only the measured date on temperature.
