Production with irrigation is high and some of the economic advantages of irrigation farming are given. To achieve this high and steady rate of production, engineering and hydraulic principles must be followed in the design and construction of the border strips. If pasture is irrigated more than five times an economic advantage exists for a border strip length of 220 m as compared with 110 m or 440 m. As lengths of border strips are shortened, watering rates are increased and a greater area can be covered with the same amount of water or the area may be watered more frequently.
