Proportional Study of High Irrigation Efficiency over Conventional Irrigation Method on Yield Potential and Water Use Efficiency of Sunflower Crop at Lower Kohistan of Sindh

Abstract

The paper is based on investigations for the proportional outcome of High Irrigation Efficiency system of drip technique over Conventional method of furrow irrigation technique on potential of seed yield and water use efficiency, the study was carried out during the year 2007. The crop was sown on April 15, 2007 and harvested on July 8, 2007. The results revealed that the higher potential of yield with slighter water application was recorded in drip technique over furrow technique of irrigation system. Consequently, water use efficiency in drip was 189.5% more than furrow technique of irrigation. The water saving in drip technique was recorded as 56% over furrow technique of irrigation method along with an increase of 25.6% in potential of crop yield. Taken as a whole, it is proved that drip technique dominated over furrow technique of irrigation system in respect of water use, potential yields, water use efficiency and water saving. The approach on scientific data generated through this study would serve as a bench mark and would help to those scientists, irrigation and agriculture engineers, researchers and students who are engaged in similar type of activities for further research. To achieve the optimum targets of growing demand in reflection of increasing populations, more land can be taken under cultivation from the limited water resources.
