This study is an attempt to examine some of the economic issues of date production covering 315 farms in Saudi Arabia, using different analytical and empirical techniques. The results indicated that the date production process is exhibiting constant return to scale in the long-run, though in the short-run it exhibited decreasing returns to scale due to the limitation posed by their inability to adjust to farm size. The effect of water input on production is highly significant. Further, the results revealed that government policies, such as input price subsidies, have had negative effects on input use efficiency. We estimated production efficiency based on a stochastic production frontier model using maximum likelihood estimation procedures. The findings of the study indicated that overall production efficiency which is currently at 64%, can be improved substantially by improving both technical and allocative efficiencies which are at 74% and 87%, respectively. There was a very perceptible effect of farm size on the efficiency level, indicating as the size of farm increases, the level of efficiency also increases. Therefore, the smaller farms are less efficient than the larger farms. The effect of socioeconomic factors such as education level, age of the farmer, ownership type, and irrigation type on the level of efficiency were tested to understand the relation between those factors and the improvement of productivity. It was observed that the size of farm, education level and age of farmer have a positive effect in reducing inefficiency both technically and allocatively. The trust ownership and government project irrigation type had negative effect on economic efficiency. The research recommended some reforms in present government policy instruments to improve the productivity and efficiency of date production. These changes include subsidizing capital for small farmers in order to bridge capital gap and to encourage these farmers to expand their farms so as to reap the benefits of scale economics and thereby helping to correct the distortions in income distribution across different groups of farmers
