Litchi is a popular and high-value fruit crop grown mainly in parts of Bihar, Uttar Pradesh, West Bengal, Jharkhand, and some northeastern states of India. To get good flowering, fruit set, and quality fruits, proper fertilizer management is very important. Many farmers face problems like poor flowering, fruit drop, or small-sized fruits mainly due to imbalance or wrong timing of fertilizer application. Understanding the correct fertilizer dose for litchi helps in maintaining healthy trees and getting better yield.
The fertilizer requirement of litchi depends on the age of the tree. Young plants need less fertilizer, while bearing trees require higher and well-balanced nutrients. Litchi trees mainly need nitrogen, phosphorus, and potassium along with organic manure. Micronutrients also play an important role, especially in fruit quality.
For young litchi plants (1–3 years old), fertilizer should be applied in small quantities to support vegetative growth. Generally, about 10–20 kg of well-decomposed farmyard manure per plant per year is sufficient. Along with this, around 100–200 grams of nitrogen, 50–100 grams of phosphorus, and 50–100 grams of potassium can be applied. These doses should be split into two applications during the year.
For non-bearing litchi trees (4–6 years old), the fertilizer dose should be increased gradually. About 25–30 kg of farmyard manure per plant per year is recommended. Along with this, around 300–400 grams of nitrogen, 200 grams of phosphorus, and 200 grams of potassium can be applied annually. This helps in building a strong canopy and prepares the tree for future fruiting.
For bearing litchi trees (7 years and above), higher fertilizer doses are required. A common recommendation is about 40–50 kg of well-decomposed farmyard manure per tree per year. In addition, around 600–700 grams of nitrogen, 300–400 grams of phosphorus, and 400–500 grams of potassium should be applied per tree annually. Proper nutrition at this stage improves flowering, fruit size, sweetness, and overall yield.
Fertilizer application should be done in two split doses. The first dose is usually applied after harvest or during early monsoon, which supports vegetative growth. The second dose is applied before flowering, usually in September or October, to support flower bud development and fruiting. Fertilizers should be applied in a circular trench around the tree canopy and mixed well with soil. Fertilizer should not be applied very close to the trunk.
Micronutrients like zinc, boron, and iron are also important for litchi. Deficiency of these nutrients can cause poor flowering and fruit drop. If deficiency symptoms are noticed, foliar sprays of micronutrients can be given at the appropriate stage.
Proper irrigation should be maintained after fertilizer application so that nutrients are absorbed efficiently. Waterlogging should be avoided, as it can damage roots. Mulching with organic matter helps retain moisture and improves soil health.
In conclusion, correct fertilizer dose and proper timing are key factors in successful litchi cultivation. Using adequate organic manure, balanced nitrogen, phosphorus, and potassium, and paying attention to micronutrients helps farmers get healthy trees, good flowering, and high-quality litchi fruits with better market value.
