Pear Production (Pyrus communis L.) in Jerusalem, Palestine

Abstract

Pear is a tree belonging to the Rosaceae family, sensitive to different environmental conditions. It is spread in East and West Asia, America and the European Union, and its production has an economic role for many countries of the world, including Palestine. Average annual temperatures and precipitation were analyzed using data from the Palestinian Meteorological Station affiliated with the city of Jerusalem, which was recorded between the years (1993-2014), and equal to the number of years of pear production, noting that the data for pear production was taken from the Palestinian Central Bureau of Statistics. On the other hand, we used Professor Salvador Ravers Martins' methodology to classify the Earth in the process of analyzing environmental factors, there are two aspects of the factors: The first is climatic, which is the amount of rain or precipitation, mean monthly temperature and soil water reserve, and the second factor is the bioclimatic, which is annual ombrothermic index, simple continentality index, compensated thermicity index, and water deficit. Moreover, we used Professor Salvador Rivers Martinez's methodology for classifying the land in the process of analyzing dependent and independents factors (environmental factors). There are two aspects to the factors: First is climatic, precipitation, mean monthly temperature and soil water reserve, and the second factor (bioclimatic factor), as simple continentality thermicity index, annual ombrothermic index, water deficit and compensated thermicity index.
