Agronomy QUESTION #2068
Question 1
Relay intercropping is distinguished from simultaneous intercropping in that:
  • Both crops are planted on the same date in relay cropping
  • In relay intercropping, the second crop is planted into the standing first crop before it is harvested, so the two crops overlap only for part of their respective growing seasons — optimizing land use and extending the effective growing season✔️
  • Relay cropping always involves a cereal–legume combination while simultaneous intercropping is limited to two cereals
  • Relay intercropping requires wider row spacing than simultaneous intercropping
Correct Answer Explanation
Relay intercropping staggers planting times: Crop 1 is established first, and Crop 2 is seeded into it while Crop 1 is still growing (often near maturity). This extends total land occupancy, reduces competition during critical periods, and allows double or triple cropping in areas with short growing seasons — e.g., wheat–mungbean relay in Punjab.
