Cotton in Egypt has an important economic situation. Thus the study aimed to evaluate the expected economic effects and productivity of environmental factors on Egyptian cotton production. This comes by predicting production yield value and evaluating its return due to cultural and environmental desired and undesired variables. So, convenient production pattern could be determined to obtain maximum yield under these variables effect. The study clarified that expected cotton yield under desired environmental variables will be ranges between 4169-4336 thousand quintar, with an average equal 4253 thousand quintar. This production will realize national net income ranges between 429.37- 474.68 million L.E., with an average equal 452.03 million L. E. Meanwhile, the expected cotton yield under undesired environmental variables ranges between 3171- 3338 thousand quintar with an average equals 3255 thousand quintar. This yield will realize national net income ranges between 33.37- 78.60 million L. E. with an average equals 55.99 million L.E. The study also indicated that cotton crop is one of the extremely affected crops by the environmental and cultural variables extended in its production zones due its long life period. This is detected by its decrease in the production value undesired environmental factors, where this decrease ranges between 23.02% to 23.94% of the
