Information Regarding Fertilizer Doses in Kinnow
The kinnow, also known as the mandarin orange or tangerine, is a citrus fruit widely cultivated in India and Pakistan. It is known for its juicy and sweet pulp, as well as its high vitamin C content. However, like any other crop, kinnow trees require proper care and inputs to ensure optimal growth and yield. One of the key inputs for kinnow cultivation is fertilizers. In this article, we will discuss the recommended fertilizer doses for kinnow trees.
Fertilizer Requirements of Kinnow Trees
Kinnow trees have specific fertilizer requirements that vary according to their age, soil type, and climate. The following are the major nutrients required by kinnow trees:
– Nitrogen (N)
– Phosphorus (P)
– Potassium (K)
Apart from these macro-nutrients, kinnow trees also need micronutrients like iron (Fe), manganese (Mn), zinc (Zn), copper (Cu), and boron (B) in small quantities.
Recommended Fertilizer Doses for Kinnow Trees
The following are the general fertilizer doses recommended for kinnow trees:
1. Nitrogen:
– For young plants (1-2 years old), apply 300-400 grams of nitrogen per tree per year.
– For mature trees (3 years and above), apply 1 to 1.5 kg of nitrogen per tree per year.
2. Phosphorus:
– For young plants, apply 150-200 grams of phosphorus per tree per year.
– For mature trees, apply 400 to 500 grams of phosphorus per tree per year.
3. Potassium:
– For young plants, apply 200-250 grams of potassium per tree per year.
– For mature trees, apply 700 to 800 grams of potassium per tree per year.
4. Micronutrients:
– Apply 30 to 40 grams of zinc sulfate and 10 to 15 grams of borax per tree per year.
– Apply 10 to 15 grams of copper sulfate and manganese sulfate per tree per year.
It is important to note that these doses are general guidelines and may vary based on soil analysis, climate, and other factors. It is advisable to consult a local horticulturist or agricultural expert for specific fertilizer recommendations.
Fertilizer Application Methods
Fertilizers can be applied to kinnow trees in different ways, such as:
– Broadcasting: Spreading fertilizer uniformly on the soil surface around the tree and then mixing it with the soil using a cultivator or hoe.
– Spot application: Applying fertilizer in small holes made around the tree’s canopy, where the feeder roots are concentrated.
– Foliar application: Spraying a liquid fertilizer solution directly on the leaves of the tree. This method is useful for providing quick nutrient uptake and addressing nutrient deficiencies.
Conclusion
Fertilizers play a vital role in the growth and yield of kinnow trees. By providing the right amount of nutrients at the right time, farmers can ensure healthy and productive trees. It is essential to follow the recommended fertilizer doses and application methods for optimal results. Regular soil testing and consultation with experts can help farmers fine-tune their fertilizer management practices and achieve high-quality kinnow produce.
