Irrigation plays a very important role in producing various crops all over the world. There are some areas where no crops are able to grow without irrigation. Apart from those areas, rain fed agriculture is dominant. To stabilize and increase crop yield in semi-arid area, where rainfall is insufficient and unreliable even during rainy season, supplemental irrigation is essential. Main characteristic of irrigation agriculture in Karakalpakstan is that crop production is strongly relying on irrigation water because of low precipitation. And also lower temperature in winter and government control of cotton and wheat marketing are affecting the agriculture in Karakalpakstan. Field Research conducted in Karakalpakstan (Chimbay and Nukus districts) in August/September is a part of research entitled “Water quality impacts to Agriculture products in case of Karakalpakstan, Uzbekistan”. The research aims to explore impacts of water quality to agriculture products through Questionnaire Surveys.
Key words: Farmers, irrigation, crop yield, questionnaire survey, productivity
