Which of the following will not increase the efficiency of water use by plants in an irrigation system? 52
A) The use of concrete-lined delivery ditches
B) The use of flood irrigation for forage crops
C) The use of drip irrigation for fruit trees
D) The use of crop residues to reduce evaporation
E) The use of herbicides to control weeds

Question

Quizplus · Accepted Answer

Flood irrigation involves a large amount of water being applied to the field at once, which can result in significant water loss due to runoff, evaporation, and deep percolation. This method is not efficient for water use by plants. The other options (A, C, D, and E) can all increase efficiency of water use by plants in an irrigation system. Concrete-lined delivery ditches can reduce seepage losses, drip irrigation allows for precise application of water to the root zone of plants, using crop residues can reduce evaporation losses, and using herbicides decreases competition for water between crops and weeds.
