Egypt's climate center has warned of the impact of a heatwave on crops and trees, particularly those that are sensitive to temperature fluctuations. The center's head, Dr. Mohamed Ali Fahim, stated that the heatwave, which is expected to hit the country in early November, could have devastating effects on crops and trees, especially those that are newly planted. He emphasized the need for caution and careful monitoring of weather conditions.
The heatwave, which is expected to be followed by a rapid drop in temperature, could lead to thermal shocks that affect plant growth and physiological processes. This, in turn, could increase water loss, particularly in young plants that have not yet adapted to changing weather conditions. Dr. Fahim noted that winter crops, such as potatoes, sugar beets, onions, garlic, strawberries, and autumn vegetables, require close monitoring during this period.
Dr. Fahim also highlighted the vulnerability of fruit trees, which require special attention during this time. He noted that the heatwave could lead to increased respiration rates, consuming some of the stored nutrients that trees have accumulated during the previous season. For mango trees, continued vegetative activity could affect their ability to flower, particularly if the trees have not yet completed their growth.
The climate center has identified several key areas that require attention, including the need to monitor pests and diseases that thrive in changing weather conditions. Dr. Fahim noted that pests, such as aphids, whiteflies, and thrips, require close monitoring, and that farmers should avoid using preventive pesticides without evidence of infestation.
To mitigate the effects of the heatwave, the climate center has issued seven recommendations for farmers. These include avoiding over-irrigation of newly planted crops, adjusting irrigation schedules according to soil type and crop needs, and avoiding excessive nitrogen fertilization. Farmers are also advised to closely monitor crops, such as strawberries and potatoes, and to control pests and diseases.
The climate center's recommendations also emphasize the need for careful timing in agricultural practices. Farmers are advised to avoid pruning or stimulating flowering during periods of high heat or wind activity. Additionally, they should avoid rushing into dormancy-inducing treatments for trees, and instead, carefully monitor their condition.
Dr. Fahim emphasized that responding effectively to weather fluctuations requires an understanding of plant needs and careful monitoring of their physiological state. He noted that the timing of temperature changes may be more critical than the actual temperature increases. By following these recommendations, farmers can minimize the impact of the heatwave on their crops and trees.
