可以通过采用改进的生产技术或提高效率或两者兼而有之来提高稻农的生产力。但是由于尼日利亚农民对改良水稻技术的采用率很低，提高效率成为短期内提高生产力的最佳选择。由于几乎缺乏关于全国特别是克罗斯河州小规模沼泽稻生产的农场级技术效率的经验信息，因此使用最大似然技术估计了一个包含低效率因素的随机前沿函数，该函数利用从克罗斯河州112名小规模沼泽稻农获得的数据提供了技术效率及其决定因素的估计。结果表明，稻农技术效率不高。获得的平均效率为77%，表明有23%的改进效率的余地。结果还表明，农民的受教育程度、合作社/农民协会成员资格和信贷获取对农民的效率有显著的正向影响。所涉问题是，应在国家制定和执行鼓励受过教育的人成立和加入合作社并使他们容易获得正式信贷的政策。
The productivity of rice farmers can be raised either by adoption of improved production technologies or improvement in efficiency or both. But with the low rate of adoption of improved rice technologies by farmers in Nigeria, improvement in efficiency becomes the best option in productivity enhancement in the short run. As a result of the near absence of empirical information on farm-level technical efficiency in small scale swamp rice production in the country generally and Cross River State in particular, a Stochastic Frontier function that incorporated inefficiency factors was estimated using a Maximum Likelihood technique to provide estimates of technical efficiency and its determinants using data obtained from 112 small scale swamp rice farmers in Cross River State. The results indicate that, the rice farmers were not fully technically efficient. The mean efficiency obtained was 77 percent indicating that there was a 23 percent allowance for improving efficiency. The result also shows that, farmers' educational level, membership of cooperative/farmer association and access to credit significantly influenced the farmers' efficiency positively. The implications are that policies that would encourage educated persons to form and join cooperatives and provide them with easy access to formal credit should be made and implemented in State.
