Citrus

Its global importance is reflected in its extensive cultivation in tropical and subtropical regions. Citrus also has a significant socio-economic and cultural impact on societies worldwide.

The fruit's numerous nutritional and medicinal benefits make it indispensable in many parts of the world. Primarily, citrus is valued as a fruit that is either consumed fresh or processed into juice.

• Increases productivity, enhances fruit characteristics and quality, and extends the export window.
• Boosts sugar content and improves fruit coloration.
• Promotes flowering and fruit set while reducing fruit drop.
• Enhances plant resistance to various pathogens (fungal and insect).
• Improves plant resistance to environmental stress factors such as high temperatures, frost, drought, and salinity.
• It increases the ability of roots to absorb nutrients and plays a major role in balancing carbohydrates and nitrogenous substances by reducing excessive nitrogen levels.

• Improves and boosts flowering, pollination, and fertilization.
• Improves growth and root distribution, especially at the beginning of spring growth.
• Plays a vital role in improving vegetative growth.
• Maintain long-term productivity.
• Enhances the quality of fruit juice.
• Produces fruits with excellent export specifications.

• Essential for root growth and distribution, as well as vegetative growth.
• Increases fruit set and decreases fruit drop.
• Reduces physiological disorders in fruits, such as creasing and splitting.
• Enhances the storage ability of citrus fruits in the market.
• Increases plant resistance to insect and fungal pathogens by strengthening plant cell walls.

• Poor fruit set and decreases both yield and fruit quality.
• General weakness in vegetative growth due to potassium deficiency.
• Potassium deficiency causes the death of young leaves, while older leaves become wrinkled and leathery. Additionally, leaves experience a reduction in chlorophyll content, resulting in irregular yellow spots that fall after the flowering period.
• Trees become less resistant to unfavorable environmental stress.
• Overall weakness in trees with poor vegetative growth.
• Poor sugar content and coloring in fruits.

• Reduces vegetative and root growth.
• Increases percentage of flowering and fruit set falling.
• Fruits become highly acidic.
• Thick, rough-textured fruit peel.
• Phosphorus deficiency may limit the absorption of other elements.

• Poor root growth and distribution.
• Reduces fruit set, with increased flower and fruit drop.
• Physiological disorders in fruits, such as creasing and splitting.
• Reduces storage ability of fruits in the market.
• Deformation and poor growth of young leaves.
• Death of the terminal buds on the branches.
