This thesis aims at studying the effect of climate on the rate of olive productivity in the West Bank and the relationship between the most effective elements of climate on the productivity of olive such as: (temperature, quantity of annual rainfall, rate of moisture, wind speed) from the beginning of budding (shooting) to full growth or maturity. The study also examines the extent of relationship between olive productivity and several variables such as ( olive categories, nature of cultivated land, type of soil, weedkillers, ploughing , shearing or cutting branches with secateurs, fertilization , catching with olive flies and catching with the disease of peacock eye. Besides that , the study discusses the relationship between the bio-climatic classification and the olive productivity. The study consists of six chapters: The fist chapter deals with the theoretical frame, the second chapter deals with olive product in the West Bank; the third chapter tackles the environmental factor affecting the productivity of olive oil in the West Bank; the Fourth chapter clarifies the effect of caring with olive trees on their productivity ; and the Fifth chapter deals with conclusions (results) and recommendations. The most important result is the availability of a close relationship between the climatic elements in the periods of fruit growth: (budding, blossomy, shooting, fruit growth and maturation or ripeness) and the olive productivity in the West Bank. In addition to that; the study concludes the availability of relationship between the moisturized and semi-moisturized bio-climatic classification on monthly , annual and semestrial or semi-annual level and the high productivity of olive oil; and there is also a relationship between synchronization of dry and semi-dry climatic classification and the low productivity of olive oil. The study also clarifies the relationship between productivity and the agricultural operations related to the olive tree.
