The farming technique that must be used in order to grow crops on the Deccan Plateau is:
1. Irrigation: Due to the semi-arid climate of the Deccan Plateau, where rainfall can be limited and erratic, irrigation is crucial for successful crop cultivation. By providing water artificially through irrigation methods such as canals, wells, or drip irrigation, farmers can ensure that their crops receive an adequate water supply to grow and thrive.
2. No-till: No-till farming is a technique where the soil is left undisturbed by tilling machinery. This method helps in retaining soil moisture and nutrients, reducing erosion, and improving soil health, which can be particularly beneficial in regions like the Deccan Plateau with fragile soil conditions.
Both irrigation and no-till practices are important for sustainable agriculture on the Deccan Plateau, allowing farmers to overcome challenges posed by the region's climate and soil characteristics to achieve successful crop yields.
