- To Simulate efﬁciencies of conventional (ﬂood irrigation) and alternative irrigation practices (furrow, alternate furrow, and raised bed).
- To evaluate the changes in yield and water saving on wheat crop to compare alternative and ﬂood irrigation.
- Perform analysis on capacity and economic for each water limiting scenario and suggest best irrigation system to growers for conservation of water at farm level.

Water management is one of the crucial components for various dimensions such as agribusiness, municipality, urbanization, and fisheries. One of the water-oriented dimensions is irrigation. In Pakistan, there is lack of water system planning and management for water conservation. This study was an effort to focus on water conservation using cost effective irrigation practices and the field data were used in SIRMOD model to simulate all the efficiencies. This study is based on comparative fieldbased analysis between four irrigation techniques: flood irrigation (conventional), furrow, alternate furrow, raised bed, and model based analysis on wheat crop to determine the most efficient irrigation technique and optimum efficiencies for each practice on clay loam soil.
Wheat crop was cultivated in Rabi season (2016-17) on an area of one acre on a land of a local farmer of district Sujawal, Sindh. Randomized complete block design (RCBD) method was used to design and allocate three subplots for irrigation method and determine four application efficiencies for each practice such as application efficiency of system, irrigation efficiency, distribution uniformity and requirement efficiency. The results showed that efficiency of water conserved by using furrow irrigation system was 25%, alternate furrow conserved 49% and raised-bed gave 31% in comparison to conventional method. Crop yield indicated that furrow irrigation and raised-bed technology gave higher yields than the others as increase in yield was 26% by using raised-bed technique and 17% by furrow irrigation technique whereas by using alternate irrigation it was 13% in comparison with conventional irrigation using at farm level. The model-based analysis was performed by using SIRMOD model: it was concluded that raised bed and alternate furrow produced better yield as compared to flood irrigation.
