Drylands constitute the land both on steep slope and flat valley plains where water resource (surface and ground water) are not sufficient and hence, agriculture depends on rainfall. The arable land depends entirely on rainfall for crop production and the practice of agriculture here is called dryland farming. Drylands cover a vast area of earth. Drylands are generally poor in productivity. Most of the crops and varieties grown in drylands are subsistence oriented with low yields. The cultivars are of longer duration, photosensitive and have a low harvest index with low response to inputs. |
