Which one of the following is NOT cultivated under wetland farming?

The correct answer is Option (4) → Ragi

In wetland farming the rainfall is more than the soil needs during the rainy season, so the crops grown are water-loving. Ragi, a hardy millet, is a crop of dryland farming, grown where rainfall is low, like jowar and bajra.

Rice, jute and sugarcane need plenty of water, so they are the typical crops of wetland farming.
