Effect of bioclimate factors on olive (olea europaea l.) yield: to increase the economy and maintaining food security in Palestine

Abstract: 

Olive (oleae europaea L.) is one of the most important agricultural crops production and plays a role in the Palestinian economy, we analyzed the mean monthly temperature and precipitation using data from nine weather stations from the Palestine Meteorological Department, recorded in the period from 1993-2008, with the same years plant production (rain-fed) from the Palestinian Central Bureau of Statistics (PCBS). Statistical tests included a bioclimatic analysis of Palestinian meteorological stations for the period previous by using bioclimatic classification of the Earth of Salvador Rivas Martinez, with regard to bioclimate factors as simple continentality index, compensated thermicity index, and annual ombrothermic index. In concluded, when we applied a correspondence analysis Bethlehem, Jerusalem and Ramallah areas were influenced by the annual ombrothermic index and simple continentality index, while Jenin, Nabuls, Tubas, Tulkareem and Salfite were affected by compensated thermicity index with large a proportion of the variance explained by axes 1 (84.98 %). We indicated that in the upper inframediterranean  to mesomediterranean environments, the optimum for the olive production is achieved with value of annual ombrothermic index ˂ 3.6, simple continentality index value between 15-22 and compensated thermicity index value between 280-450.
