Plant breeders at the Arid Zone Research Institute have spent a decade developing sorghum varieties that survive on roughly half the water conventional strains require. The key adaptation lies in root architecture: the new strains grow deeper, thinner roots that reach moisture reserves far below the surface, rather than the shallow, wide root systems of standard sorghum. Field trials across three drought-prone provinces showed yields dropping by only ten percent during severe dry spells, compared to a sixty percent drop in conventional crops. The institute cautions, however, that these varieties are not a universal fix, since they perform poorly in waterlogged soil and require careful selection based on local rainfall patterns before farmers adopt them.
