The present study aimed to predict the expected production of summer maize crop under suitable and unsuitable environmental factors. Also, to estimate the expected effect of the environmental factors on the production technique of summer maize crop that reflects the amount of loss in yield due to the unsuitable environmental factors. The study showed the environmental and agricultural requirements of the crop. Also, the study revealed the nature of variance in the Egyptian agricultural environment. The study showed that the total production of summer maize yield under the appropriate environmental factors ranges from 4272 to 4357 thousand Ardab (Ardab = 140 kg.) with an average of 4315 thousand and with a value of 5084 to 5184 million LE with an average of 5134 million LE under the unsuitable environmental factors, the total production of summer maize yield is expected to be 4153 to 4251 thousand with an average of 4202 thousand and with a value of 4943 to 5059 million LE with an average of 5001 million LE. Faddan productivity under suitable environmental variables is expected to be 24.57 to 25.05 and with an average of 24.81 and/fed under the unsuitable environmental factors, the productivity is expected to be 23.89 to 24.45 and with average of 24.17 and/fed. The study indicated that the maize crop has low sensitivity to the effect of agricultural and environmental variables in its production regions. This is reflected in the reduction of maize production due to unsuitable environmental variables where the loss amount of the production is 2.8% of the expected production.
