Pomegranate is an important fruit crop grown in many parts of India, valued for its high market demand and good returns. To achieve healthy plants, good flowering, and high-quality fruits, proper nutrient management is essential. Pomegranate trees need a balanced supply of major and micronutrients throughout the year. When nutrients are supplied correctly, the plant grows well, produces uniform fruits, and remains less prone to diseases and disorders.
Before planting, the field should be well-prepared with organic manure. Adding 20–25 kg of well-decomposed farmyard manure (FYM) or compost per pit improves soil structure, increases fertility, and supports long-term productivity. Organic matter also enhances water-holding capacity, which is important for pomegranate, especially in dry regions.
Pomegranate requires three main nutrients: Nitrogen (N), Phosphorus (P), and Potassium (K). Each plays a specific role in plant growth. Nitrogen supports leaf development and overall growth. Phosphorus strengthens roots and helps in flowering. Potassium improves fruit size, colour, sweetness, and resistance to diseases.
For a mature pomegranate plant, the recommended annual fertilizer dose is usually around:
200–250 g Nitrogen
150–200 g Phosphorus
150–250 g Potassium
These values can vary depending on soil fertility, irrigation, and plant age. The total fertilizer should be split into 2–3 doses during the year. The first dose is applied at the start of the growth cycle, the second during flowering, and the third during fruit development.
Micronutrients also play an important role. Deficiencies of iron, zinc, boron, and magnesium can lead to yellowing leaves, poor flowering, fruit cracking, and reduced yield. Foliar sprays of micronutrient mixtures help correct these deficiencies quickly. For example, iron chelate helps control chlorosis, while boron improves fruit setting.
Pomegranate farmers often follow bahar management, which involves pruning and regulating the flowering season. During each bahar (ambi, mrig, or hasta), fertilizers should be applied after pruning and just before irrigation. This ensures that nutrients reach the roots when the plant begins active growth.
Irrigation plays a key role in nutrient uptake. Applying fertilizers when the soil is too dry reduces absorption, while applying them in waterlogged conditions causes nutrient loss. Drip irrigation is ideal for pomegranate because it provides uniform moisture and allows fertigation—applying soluble fertilizers through the drip system. This improves nutrient use efficiency and reduces wastage.
Using biofertilizers such as Azotobacter, Azospirillum, and phosphate-solubilizing bacteria (PSB) is also beneficial. These microorganisms help convert unavailable nutrients into forms that roots can absorb. They also improve soil health in the long run.
Farmers should conduct a soil test once every 2–3 years. Soil test results help determine the exact fertilizer needs, prevent overuse, and save costs. For example, if the soil already has enough phosphorus, farmers can reduce P fertilizers and focus on nitrogen or potash depending on the requirement.
In simple words, nutrient management in pomegranate includes using organic manure, applying balanced NPK fertilizers in split doses, ensuring micronutrient sprays, maintaining proper irrigation, using biofertilizers, and following bahar-based fertilization. When farmers follow these practices, their pomegranate orchards grow healthier, produce more fruit, and give better returns year after year.
