1、NUTRITION AND FERTILIZATION IN MANGO. LITERATURE REVIEW
It is also indicated that experiments done in mango comparing organic and inorganic sources of fertilizers have not shown clear differences regarding nutrient absorption and yield; and that organic fertilizers are applied directly to the soil or, in some cases, through fertigation.
2、Nitrogen uptake and macronutrients distribution in mango
We assessed the effects of N fertigation regime on nutrient uptake and distribution in leaves and fruit of mango cv. Keitt grown in a lysimeter for four years.
3、Nitrogen as a regulator for flowering time in plant
In this review, we summarize prominent mechanisms and key players that govern the N-dependent response of flowering time, and further discuss the interaction between N utilization and growth phase transitions in plants.
4、Unlocking the role of nutrients in the induction of mango flowering
The critical role of maintaining a balanced carbon-to-nitrogen ratio, implementing strategic nutrient management (particularly nitrogen, phosphorus, and potassium), and comprehending the source-sink relationship for optimal flower induction.
5、How do preharvest applications of nitrogen fertiliser affect branch
Nitrogen fertilizer directly affected the yield, fruit quality, and metabolites of peach at different growth stages. RNA-Seq was used to analyze the influence of N levels at PH and FE in peach.
Fertilizer and nutrient dose in mango fruit – AgriBot
Each nutrient plays a significant role in the various stages of mango’s life cycle, from flowering to fruit development. Nitrogen (N): Nitrogen is vital for vegetative growth, leaf production, and overall tree vigor.
Table of Contents
Excessive or poorly timed nitrogen (N) application can negatively impact mango quality by promoting excessive or unwanted vegetative flush, which can divert calcium (Ca) away from the fruit and lead to issues such as:
Enhancing mango yield and soil health with organic and slow
Incorporating 25% organic or slow-release nitrogen ensures soil ecological sustainability. Excessive utilization of chemical fertilizers in mango orchards not only hampers the attainment of sustainable harvests but also poses significant ecological detriments.
Best Fertilizer for Mango Tree: When to Apply and How To Apply
To encourage flower and Mango yield, additional nitrogen fertilizers are applied before the Mango trees begin to flower. Manures and fertilizers can be applied from September to October. Fertilizers are applied and added to the peripheral leaf drip at a distance of 45 to 90 cm from the stem.
How to Choose and Use Mango Tree Fertilizer
Young, non-fruiting mango trees benefit from higher nitrogen content to encourage robust vegetative growth. An NPK ratio like 6-2-4 or 8-4-8 supports initial establishment and canopy development.
The role of nitrogen fertilizer during the mango flowering period is critical, as it profoundly impacts the growth, development, and fruiting of mango trees. Nitrogen, one of the three essential macronutrients for plants, is vital for mango trees. Proper application can promote healthy growth, improve fruit quality, and increase yields.
1. Promoting Growth
Nitrogen is a foundational element for synthesizing proteins, chlorophyll, and other key substances in plants. A deficiency can directly impact normal growth, leading to stunted plants, yellowed leaves, and reduced flowering. Applying an appropriate amount of nitrogen fertilizer during the flowering period strengthens the tree’s structure, laying a solid foundation for fruit development.
2. Enhancing Flower Bud Differentiation
Nitrogen supply closely regulates flower bud differentiation in mango trees. Adequate nitrogen during this stage increases flower quantity and fruit set rates, which is crucial for boosting both yield and fruit quality.
3. Boosting Photosynthesis
Nitrogen is an essential component of photosynthesis, participating in enzyme-catalyzed reactions within plants. Proper nitrogen application during flowering enhances photosynthetic efficiency, providing ample nutrients for the tree’s growth and development.
4. Improving Disease Resistance
Mango trees are prone to pests and diseases, but nitrogen strengthens their defense mechanisms. Balanced nitrogen use during flowering helps prevent infections and safeguards tree health.
Risks of Overapplication
Excessive nitrogen, leads to negative effects. Overapplication causes rapid, weak growth (e.g., thin stems, pale leaves), reduces fruit quality, and diminishes flavor, ultimately harming market appeal.
Best Practices for Nitrogen Application
To optimize results and avoid risks:
- Soil Testing: Determine nitrogen needs based on soil tests. For most mango orchards, 15–20 kilograms of urea per mu (approx. 0.067 hectares) is sufficient.
- Fertilizer Selection: Use specialized compound fertilizers (e.g., urea, potassium nitrate) or organic options (e.g., chicken/cow manure).
- Timing and Method: Apply in early morning or late evening via trench, hole, or broadcast spreading near roots for efficient absorption.
- Balanced Nutrients: Combine nitrogen with phosphorus and potassium fertilizers to meet the tree’s full nutritional needs.
Scientific nitrogen management during the mango flowering period is vital for robust growth, flowering, and fruiting. While nitrogen is indispensable, strict control of application rates ensures sustained tree health and high-quality yields.
