- Apreparation of land and sowing
- Bsowing and harvesting of a cropCorrect
- Csowing and the last watering before harvesting a crop
- Dpreparation of land and last watering before harvesting a crop
Solution
Concept
Crop period is the full time from sowing to harvesting of a crop.
Step-by-step solution
1. Crop period = number of days the crop stays in the field. 2. The crop is in the field from sowing until harvesting. 3. So crop period = time between sowing and harvesting. 4. Answer is option B.
Explanation
Crop period is the time from sowing of the crop to its harvesting. Base period is a different term. It is the time from the first watering (for land preparation) to the last watering before harvest. Crop period is usually a little longer than base period.
Why the other options are wrong
A: Land preparation to sowing is only the pre-sowing stage, not the crop life. C: Sowing to last watering leaves out the days after the last watering till harvest. D: First watering for land preparation to last watering before harvest is the definition of base period, not crop period.
Shortcut
Crop period = sowing to harvesting. Base period = first watering to last watering.
Common mistake
Mixing up crop period with base period (option D).
Correct answer: B) sowing and harvesting of a crop
