Sugarcane is the crop among the options that is not typically cultivated under dryland farming conditions. Dryland farming is practiced in regions with low and erratic rainfall, and the crops grown are selected for their ability to tolerate drought or mature quickly using limited moisture.
Jowar (Sorghum), Ragi (Finger Millet), and Groundnut are common rain-fed crops suitable for cultivation in dryland areas due to their drought tolerance. Sugarcane, however, is a water-intensive crop requiring significant and consistent irrigation for optimal growth, making it unsuitable for dryland farming where irrigation is limited or unavailable.
Dryland farming aims to conserve soil moisture, utilize available rainfall efficiently, and cultivate drought-resistant crops. Examples of crops suited for dryland farming in India include millets (Jowar, Bajra, Ragi), pulses (gram, moong, arhar), oilseeds (groundnut, sesame, castor), and cotton in some areas. Sugarcane cultivation is concentrated in areas with assured irrigation facilities, either from canals, wells, or abundant rainfall.
