Persimmon (often called “Japanese fruit”) is still a less common fruit crop in India compared to apple or pear, but it is gaining interest in some hill and temperate regions. Because it is a perennial fruit tree, fertilizer dose is not a fixed “one-time” number like vegetables. The nutrient requirement changes with the age of the plant, soil fertility, and the expected fruit load. The goal of fertilizer management in persimmon is to build a strong tree frame in the first few years and later support flowering, fruit setting, and good fruit quality without making the tree too leafy.
The first and most important step is improving soil organic matter. Persimmon trees respond well to well-decomposed farmyard manure (FYM) or compost. Organic manure improves soil structure, helps roots grow deeper, and supports helpful microbes. For young persimmon plants (1 to 3 years old), apply about 10 to 15 kg FYM or compost per plant per year. For bearing trees (5 years and above), apply about 25 to 40 kg FYM per plant per year depending on tree size and soil condition. Apply organic manure during winter or before spring growth so it mixes well into the soil and starts releasing nutrients when the tree becomes active.
Along with organic manure, persimmon needs balanced NPK (nitrogen, phosphorus, and potassium). Nitrogen supports new growth and leaf development, phosphorus supports root growth and flowering, and potassium is very important for fruit size, sweetness, colour, and overall quality. Too much nitrogen can lead to excessive vegetative growth, fewer flowers, delayed fruit maturity, and sometimes more fruit drop. So nitrogen should be used carefully in bearing trees.
A simple age-wise fertilizer plan can be followed in many orchards. For a 1-year-old plant, you can apply roughly around 50–60 grams nitrogen, 25–30 grams phosphorus (P2O5), and 40–50 grams potassium (K2O) per plant in a year, along with FYM. For a 2 to 3-year-old plant, the dose can be increased gradually each year as the canopy grows. For a 4 to 5-year-old plant, the dose may reach around 200–300 grams nitrogen, 100–150 grams phosphorus (P2O5), and 200–250 grams potassium (K2O) per plant per year. For fully bearing trees (6 years and above), farmers often apply around 400–500 grams nitrogen, 200–250 grams phosphorus (P2O5), and 400–500 grams potassium (K2O) per plant per year, depending on tree size, yield level, and soil fertility. These numbers are general guidelines; in rich soils the dose can be reduced, and in poor soils it may need slight increase.
Timing and split application matter a lot. For persimmon, it is better to apply fertilizer in two splits. Give half nitrogen along with full phosphorus and half potassium just before spring growth starts. The remaining half nitrogen and half potassium can be given after fruit set or during early fruit development. This supports both growth and fruit filling. Avoid late heavy nitrogen close to harvest because it can reduce fruit quality and delay maturity.
Method of application is also important. Apply manure and fertilizers in a circular band under the canopy, away from the trunk, because feeder roots are mostly in that zone. Mix lightly into the soil and irrigate if moisture is low. Do not place fertilizer right at the trunk because it may not be used well and can sometimes damage bark.
Micronutrients like boron and zinc may be needed in some soils, especially in high pH or low organic matter conditions. If trees show poor flowering, uneven fruit set, or leaf yellowing, micronutrient deficiency may be involved. Foliar sprays can give quick correction, but they should be used in recommended dose only.
In simple terms, fertilizer dose for persimmon depends mainly on tree age. Start with lower doses in young plants and increase gradually as the tree grows and starts bearing. Use plenty of compost or FYM, apply balanced NPK with careful nitrogen management, split the dose between pre-spring and after fruit set, and place fertilizers under the canopy. With steady nutrition and good moisture, persimmon trees grow healthier and give better fruit yield and quality year after year.
