Nitrogen is necessary for leaf development. Fertilizers that support rapid leaf development, such as urea and ammonium nitrate, help onions accumulate energy. This energy is required for bulb production.
Phosphorus improves the quality of bulbs and helps with root growth. Apply superphosphate or bone meal to ensure robust roots and increase the overall durability of your onion crop.
Potassium boosts hydration retention and resistance to disease. Onions benefit from potassium sulphate and phosphate in terms of flavour, bulb growth, and resistance to stress.
Compost and well-rotted manure are examples of organic choices that improve the soil's structure and supply nutrients. They encourage the growth of onions and sustainable agricultural methods.
For optimum growth, onions need micronutrients such as iron, magnesium, and zinc. Using specific micronutrient fertilizers guarantees that your onions receive the necessary nutrients.
Applying fertilizer with the right timing and technique is essential. Also, ensure that your onions grow strongly and yield abundantly by increasing nutrient uptake through foliar feeding and side dressing.
