Abstract:
اصبح المناخ اليوم من الموضوعات الرئيسية المهمة التي تحتل مرتبة الصدارة لدى جميع دول العالم المتقدمة والنامية، لاسيما بعد ان تبين بوضوح مدى التغيرات التي شهدها في العقود الاخيرة. والتي تحدث اما لاسباب طبيعية نتيجة اختلال في توازن النظام البيئي او لاسباب بش | Climate has become a key topic that occupies the forefront of all developed and developing countries around the world, especially after the climate change witnessed in recent decades, These changes occur due to either natural causes as a result of an imbalance in the ecosystem, or human causes such as human economic activities, these changes affected many aspects of life, one of which is the agriculture, including palm cultivation and dates productionThe aim of this research was to study the effect or the relationship between climate and dates production, which is considered one of the most important crops that can be relied upon economically. This research uses the method of Multiple Linear Regression Analysis to find out the climatic elements effecting the productivity of two types of dates (Helawi and Zehdi). The independent variables (climatic side) were the average of the yearly rates for (Maximum temperatures, Sunshine duration, Relative humidity, Wind speed and Suspended dust) in Basra city for the period (2005 - 2014), and the dependent variable was the average of the palm tree productivity measured in (kg), which represents the (agricultural side). The results showed that there are three factors (variables) affecting dates production of (Helawi), which are (sunshine duration, suspended dust and wind speed) because they were statistically significant. As for the (Zehdi), there were two statistically significant variables, which are (Sunshine and Maximum temperatures). The conclusions and recommendations were founded by using the Stepwise regression in statistical package (SPSS v19)
