With regard to the article "Kingdom buys 690,000 tons of hard wheat" (Feb. 3), self-sufficiency in food must remain a top priority for all self-respecting nations. The Ministry of Agriculture of Saudi Arabia must keep experimenting and trying to achieve that objective. It all depends on the hard work and endless toil of determined minds. In the meantime, importing a basic staple, such as wheat, seems to be the sensible way forward. Muhammad Sarmad Alamgir Dar, Online response
