Dry farming is possible because of:
- AUtilization of groundwater potential
- BIntroduction of quick maturing and resistant varieties of millets
- CImprovements in technology
- DAll of the above
Solution & Step-by-step Explanation
Dry farming relies on structural and biological methods to sustain crop yields in regions experiencing low or erratic rainfall without extensive surface irrigation. This agricultural system succeeds through a combination of maximizing groundwater potential, utilizing drought-resistant, short-duration millet varieties, and adopting moisture-conservation farming technologies. Thus, all choices contribute to its viability.
