As one of the most popular and profitable fruit crops in the world, mango is cultivated extensively across various regions and is an important source of livelihood for farmers. To ensure high yields and quality produce, fertilization is a crucial aspect of mango cultivation that cannot be overlooked. Here’s a detailed guide on fertilizer dose for mango crop:
1. Soil Testing:
Before applying any fertilizers, it’s essential to test the soil to determine the pH, nutrient content, and other important parameters. This helps in determining the specific requirements of the soil and aids in the selection of the right fertilizers.
2. Nitrogen:
Nitrogen is an essential nutrient for plant growth, and mango trees require an adequate amount of it during the vegetative growth phase. The recommended dose of nitrogen for young mango trees is around 150 grams per plant per year, while mature trees require around 500-700 grams per year.
3. Phosphorus:
Phosphorus is essential for root development and fruit formation. Young mango trees require around 40-50 grams of phosphorus per plant per year, while mature trees require around 250-300 grams per year.
4. Potassium:
Potassium plays a significant role in increasing the resistance of plants to pests and diseases. Young mango trees require around 40-50 grams of potassium per plant per year, while mature trees require around 350-500 grams per year.
5. Micronutrients:
Apart from the major nutrients, mango trees require small amounts of various micronutrients such as iron, zinc, and manganese. The deficiency of these micronutrients can result in stunted growth and poor fruit quality. A balanced fertilizer that includes all these micronutrients can be applied once in every two to three years.
6. Timing and Frequency:
Fertilizers should be applied at the beginning of the rainy season when the soil is moist and nutrients get easily absorbed by the roots. The application of fertilizers should be frequent, with two to three doses spread across the season. Over-application of fertilizers should be avoided as it may lead to nutrient imbalance and cause harm to the plant.
In conclusion, fertilization is a crucial aspect of mango cultivation that requires careful consideration and appropriate dosage. By following the above guidelines, farmers can ensure healthy growth, high yields, and quality produce.
