Final answer:
Dry farming is the agricultural practice that relies on rainfall for crop production, which contrasts with irrigated farming that uses artificial means to supply water. It involves growing drought-resistant crops and using soil conservation methods to manage water sustainably, especially in regions with limited water supply.
Step-by-step explanation:
The type of agricultural production that relies on rainfall to produce crops is c. Dry farming. This method is typically used in regions with limited water resources and where the cultivation of crops depends solely on moisture from rainfall rather than artificial irrigation. Dry farming techniques often involve the selection of drought-resistant crop varieties and conservation tillage methods to preserve soil moisture. Unlike irrigated farming, which requires elaborate systems like dams and canals, dry farming is more reliant on the natural precipitation patterns and sustainable agricultural practices to achieve sufficient yields.
While irrigated farming can produce abundant harvests in arid areas by artificially providing water, it is also associated with significant water use and potential mismanagement of this precious resource. Conversely, dry farming is seen as a more sustainable approach in suitable climates. It is a strategy that aligns with water conservation practices and can be particularly important in the face of climate variability and changing rainfall patterns.
