Influence on crop yields is:
Correct answer: D. Both (a) & (b)
- A. Are carefully measured at various points on a line perpendicular to the center of the windbreak
- B. By calculation, it can be shown that the total potential yields for most crops will be 2-10% greater on the field
- C. None of these
- D. Both (a) & (b)
Explanation
Crop yield effects are measured at several points along a line perpendicular to the windbreak, allowing the protected and unprotected zones to be compared. Properly designed windbreaks can raise total potential yields for many crops by about 2 to 10%.
