Analysis of the effect of the climate factors on the orange production in Yemen

الملخص EN

Yemen unquestionably produces many quantities of Oranges.

There are about 985380 orange, which are affected by several factors.

Climate is one of the important factors.

This paper tends to focus on the effect of climate- causing an increase or a decrease- on the production of orange.

Spectrum analysis, used to analyze this problem on the production of orange in Yemen, and the extent of its effect on those working in the agricultural area in order to uncover, and solve the problems caused by climate.

This model concentrates also on temperature, rain, air relative humidity, wind and light.

The spectrum analysis, which used the correlation between the production of orange and the temperature of many periods of time, is based specifically on the following relationship: y, = j + [ E a, cosW,t sin W,' ] This relationship investigates if there is a correlation between the increase and decrease Of temperature and the poduction of orange The results show that the expected values of the production Of orange in Yemen are not as required due to the effects Of different factors like the climate.

It is found that the climate directly qffects the production of orange either by an increase or a decrease.

TO sum up, (f the temperature decreases, then production Of orange increases, and vice versa
