Wheat production in Saudi Arabia between feasibility and efficiency
通过三年实验和随机优势效率标准，评估了沙特小麦种植中种子、水和氮肥的投入效率，发现经济可行性被忽视，资源消耗严重。
The cultivation of wheat in Saudi Arabia has been claimed to be resource depletable. Huge amounts of high quality inputs, especially water, seeds, and nitrogen fertilizers, have been applied to the sandy Saudi soils to increase productivity. However, the economic feasibility of wheat production has been totally neglected, mainly for political reasons. Classical production functions analysis has not yielded significant conclusions regarding the use of inputs. A 3-year experiment on an educational farm with a soil type representative of the agricultural soil in Saudi Arabia, yielded some interesting results concerning the use of inputs. The findings were obtained through the stochastic dominance efficiency criterion which assessed the efficient levels of seeds, water, and nitrogen fertilizers in wheat cultivation when production risk was considered.
