• A. Calculation of net yield becomes easy
• B. Farmland area on earth cannot be increased indefinitely
• C. Greater yield can be obtained
• D. All of the above

Answer 1

Answer: (B), (C)

The correct options are
B Farmland area on earth cannot be increased indefinitely
C Greater yield can be obtained

All life is dependent on plants, so humans undertake practices like plant breeding to improve the quality of crops, fruits and vegetables. Even in breeding programs, the major focus is to increase the yield from the crops to meet the demands of the ever increasing population. Thus, through plant breeding crops which give high productivity are produced. Breeding is undertaken because the farmland area available is fixed. We cannot acquire new farmlands as most of the area is already in use for other activities, so the only way is to judiciously use the space that we have is to grow high yielding crops.
