Fertilization strategies play a crucial role in ensuring healthy plant growth and optimal yield. During the early stages of plant development, such as germination and the initial phase of new leaf emergence, it's essential to apply balanced fertilizers containing nitrogen, phosphorus, and potassium. To encourage rapid growth in spring, a foliar spray of 0.01% gibberellin combined with 0.1% potassium dihydrogen phosphate is often recommended. If growth control is needed, a root application of 0.5% CCC (Chlormequat Chloride) can be effective.
About 10 days before flower buds begin to differentiate, it's time to apply what is known as "flowering fertilizer." At this stage, the focus should be on phosphorus-rich formulations. A common practice is to spray a solution made by dissolving 2 kg of superphosphate and 0.2 kg of boric acid in 100 liters of water—this equates to approximately 2% SSP and 0.2% boric acid.
After flowering, the post-anthesis fertilizer becomes important. This period is ideal for applying nutrient-dense compound fertilizers that contain a wide range of essential elements. These help support fruit development and overall plant health.
Wintering fertilizer is applied roughly half a month before the first frost, typically around early November in southern regions. The primary goal is to prepare the plant for winter dormancy. Organic manure, along with phosphorus and potassium fertilizers, is commonly used. Phosphorus is usually applied at a concentration of 2–3%, while potassium is applied at about 1%. These nutrients help strengthen the plant’s root system and improve its resilience to cold weather.
Proper timing and balanced nutrient application are key to successful plant cultivation, ensuring both quality and quantity of harvest.
