Manuring & Fertilization

The nutrient requirements of litchi are very high. Apart from the major requirements N, P and K which contributes to profuse vegetative growth and flower initiation, micronutrients such as calcium, magnesium, zinc, boron and copper also play an important role in flowering and fruiting. In India, litchi is grown mostly in the fertile belt and hence very little or no fertilizer is given. However, soil analysis should be done to determine the exact doses of fertilizer.

Recommended doses of fertilizers for getting optimum yield.

1/3 dose of nitrogen, 1/2 dose of potash, full dose of phosphorous and FYM should be given in the month of June-July just after the harvesting at a distance of 1.0 - 1.5 m from the main trunk of the tree. Beside that 20-25 gm copper sulphate, zinc sulphate and boron per plant per year should be given in the month of June-July. After the application of fertilizers, light irrigation should be done. 1/3 dose of nitrogen should be given in the month of February at the time of flowering. Remaining 1/2 dose of potash and 1/3 dose of nitrogen should be given in the month of April.
