This paper describes an experiment to examine the water stress on corn yield so as to determine the economic feasibility to irrigate the crop with groundwater. It is a concise paper with useful information to the corn producers and researcher as well. However, at its curren status, it has not satisfied the level to be accepted to be published in the Journal because of multiple reasons (1) there is a great room for improving this paper by intensive English editorial work. There are several cases where the entire section is not well presented in fluent English. Some minor gramatic errors can be found in several locations as well. (2) Suggest to separate discuss and conclusion so that the value of the paper in science and production can be fully demonstrated. In particular, the scientific value of the paper has been less focused, which should be added
