Effect of distribution uniformity on application efficiency?

Effect of distribution uniformity on application efficiency?

• A. Higher DU generally improves application efficiency.
• B. Lower DU generally improves application efficiency.
• C. DU is unrelated to application efficiency.
• D. DU only affects head type selection.

Answer: (A)

Distribution uniformity describes how evenly water is delivered across the field. When DU is high, most areas receive about the same amount of water, so the water applied is more effectively used by the crop. This minimizes losses from runoff and deep percolation and reduces the need for extra irrigation cycles, boosting application efficiency. If uniformity is low, some areas get too much water while others get too little; the excess is wasted and the crop may not receive enough in parts of the field, lowering overall efficiency. So, higher distribution uniformity generally improves application efficiency.
