Climate Change and the Possibility of Tea Production in the Egyptian Soils

CLIMATE change is one of the most important global issues that impacts all our life sides. Growing crops and their productivity also are influenced by changing in the climate and climatic elements. Growing tea in non-traditional regions like Egypt could be considered a challenge due to the specific climatic and soil requirements for growing and production. However, with careful planning and experimentation, it might be possible to establish tea cultivation in such conditions. So, a lysimeter trial was conducted as an exploratory experiment aiming to assess tea cultivation performance in both sandy and clayey soil. Additionally, a separate field trial was carried out to evaluate tea growth in clayey soil along with applied organic fertilizer (chicken manure). The findings revealed that, under the lysimeter trial, tea plants exhibited robust growth on both sandy and clayey soil. Various parameters, including plant height, fresh and dry weights, leaf area, chlorophyll content, and leaf N, P, K levels, indicated superior performance on sandy soil compared to clayey soil. In the field trial, notable superiority was observed in plants grown on the organic medium containing chicken manure over those plants grown on clayey soil without such supplementation. These outcomes suggest that climate changes could potentially transform Egypt into a favorable region for tea cultivation. More studies are needed to establish a complete program of cultivation of tea including the water and nutrient requirements.
