Abstract:
ان هذه الرسالة تبحث في اثر عناصر المناخ في زراعة وانتاج محصول الرمان في قضاء المقدادية وكان هدف الدراسة الكشف عن تاثير عناصر المناخ في زراعة وانتاج محصول الرمان.ومن هنا انطلقت المشكلة البحثية (ما اثر عناصر المناخ على زراعة وانتاج محصول الرمان في قضاء المق | This study aims at investigating the effect of the climate factors in planting and producing the pomegranate in Al - Miqdadyah district.So, the study problem began from the study hypothesis which suggest that (the climate factors have an influential effect in the prosperity of the pomegranate and the determination of its ripeness time.The climate factors the study deals with are (light, temperature, wind, humidity ,rain).Moreover, the study depends on theclimate data of the weather stations in (Khanaqeen and Khalis)for 12 years from(2001 - 2012).The study is divided into four chapters in addition to the conclusions and recommendations.The study has shown that the great temperature exceeded the usual levels during the ripping time and the gathered temperature was appropriate for planting the crop in the study area ,also the studyhas revealed that the rain levels were insufficient so they depended on supplementary irrigation. Moreover ,it has been founded a noticeable outbreak of many blights such as Mediterranean fruit worm and the Pomegranate trunk - carver particularly in the east of the study area ,actually changes in trends and average towards decreasing in vaporization /exudation caused decrease in the water consumption of this crop to be reflected positively in the reduction of water ration and water inefficacy.Besides , the study has shown that the pomegranate production trend is towards decreasing as proved by the statistical devices in Khalis weather station that(speed of wind, sun brightness, normal temperature) are the most effective factors on the production of this crop ,that is the (t - test)assures the significance of these factors with(95%)whereas the (F - test)assures the significance of these factors (99%)and the value of the selection coefficient(R2) is(97%).In Khanaqeen weather station ,the factors (speed of wind, sun brightness and lowest temperature )are the most effective ones in the production of the crop,that is the (t - test)pointed out the importance of the factor is(95%)for the lowest temperature and(0.99)for the speed of wind and sun brightness , whereas the (F - test)assures the significance of these factors (99%)and the value of the selection coefficient(R2) is(99%).
