The Importance of Chelated Zinc: Recommended Dosage per Acre in India
Zinc is an essential micronutrient that plays a crucial role in the growth and development of crops. In India, the use of chelated zinc fertilizers has gained popularity due to their enhanced availability to plants. This article aims to provide information about the recommended chelated zinc dosage per acre in India, focusing on the benefits and best practices to maximize crop yield.
Understanding Chelated Zinc
Chelated zinc refers to zinc that is bound with organic molecules, which enhances its solubility and availability to plants. This form of zinc is less prone to leaching and can be absorbed more effectively by crops, making it an ideal choice for various agricultural applications.
Why is Zinc Important for Crops?
Zinc is vital for various plant functions, including:
1. Photosynthesis: Zinc plays a key role in chlorophyll production, which is essential for photosynthesis.
2. Enzyme Activity: It is a crucial component of several enzymes that facilitate biochemical reactions in plants.
3. Growth Regulation: Zinc influences plant growth and development by affecting hormone levels.
4. Disease Resistance: Adequate zinc levels contribute to enhanced disease resistance in crops.
Recommended Chelated Zinc Dose per Acre in India
The recommended dosage of chelated zinc varies depending on the type of crop, soil condition, and existing zinc level in the soil. However, a general guideline can be as follows:
– For Major Crops: The average recommended chelated zinc dose is typically between 5 to 10 kg per acre.
– Specific Recommendations:
– Cereals (e.g., Rice, Wheat): 5 kg per acre.
– Pulses (e.g., Chickpeas, Lentils): 3 to 5 kg per acre.
– Vegetables (e.g., Tomatoes, Peppers): 7 to 10 kg per acre.
– Fruits (e.g., Mangoes, Bananas): 5 to 10 kg per acre, depending on the growth stage.
Factors Influencing Zinc Application
1. Soil Test Results: Conducting a soil test is paramount to determine the existing zinc levels and decide on the necessary application.
2. Crop Type: Different crops have varying zinc requirements; understanding these needs can optimize yield.
3. Soil pH: Zinc availability is affected by soil pH. Acidic soils tend to have higher zinc availability compared to alkaline soils.
Best Practices for Applying Chelated Zinc
1. Soil Testing: Always start with a soil test to identify nutrient levels.
2. Timing: Apply chelated zinc during the critical growth stages of crops to ensure maximum uptake.
3. Method of Application:
– Foliar Spray: For immediate results, using a foliar spray can ensure quick absorption.
– Soil Application: Incorporating it into the soil can provide a slow release of nutrients over time.
4. Combine with Other Nutrients: Chelated zinc can be applied alongside other micronutrients for enhanced effectiveness.
Conclusion
Utilizing chelated zinc in agriculture is crucial for enhancing crop growth and productivity in India. By adhering to the recommended dosage of 5 to 10 kg per acre, farmers can significantly improve their yields and contribute to food security. Ensuring optimal application practices will yield the best results, helping to sustain India’s agricultural output while addressing micronutrient deficiencies.
