Climate feasibility of olive cultivation in Kermanshah Province

This study is implemented to survey and compare weather conditions in selected stations (Kermanshah, Kangavar, Islamabad Gharb, Sarpolezahab, and Ravansar) in a statistical period of at least 18 years, with bioclimatic needs of olive tree cultivation feasibility. For this purpose, regarding phonological conditions of olive and its match with needed climate effective indices in cultivation of the crop has been investigated. Using FAO - Penman - Mantys irrigation and water requirement are calculated. Finally, the temperature need and cooling degree of the crop product were estimated. Results of this study indicate that among the elements of climate, temperature is a limiting factor. The estimated irrigation and water requirements also indicated that the selected stations face dire shortage to rainfall and irrigation for producing quality product, but they are not limiting factors. Comparing climatic elements of Kermanshah with specific needs of olive climate it was indicated that the lowest temperature degree in the coldest month and the highest temperature, in the hottest month, and sunny hours have full compatibility with physiological conditions of olive.
