8. ECOLOGICAL REQUIREMENT
 Litchi is subtropical fruit
 Bearing tree is much affected by HOT
WIND causing fruit cracking
 Alluvial soil with good drainage is
suitable for litchi orchard.
 It can grow in wide range of soils
from light sandy to heavy clay.
SOIL
 The temperature should not go
beyond 40.5 0C in summer and
below freezing point in winter
TEMPERATURE

9. VARIETIES
EARLY-dehradoon(fruit have an attractive colour),
Early badam (seedless variety) ,
muzzafarpur, shahi
MEDIUM- rose santed, Mclean
LATE- seedless late(late bedana), calcttia, china

10. PROPAGATION
 Through Seed
 Through vegetative.
Litchi seed loses its viability with in 4-5days of its extraction from the fruit.
The trees raised from seeds are very slow to come into bearing and may
take 10-12 years to come to bearing.
 In vegetative propagation technique, litchi can be propagated through
cutting, budding, layering and grafting.
 AIR LAYERING(in the month June-July) is the Commercial method of
propagation.

11. PROCESS OF AIR LAYERING

12. Details Usual Practice
Planting Time • August – September
• Planting may be done in spring and early summer if irrigation facility is available
Planting Distance • 10×8m.
• Average no. of plants- 200 per ha.
Size of pits • 1x1x1 m (pits are dug a few weeks prior to planting)
Filling of pits • Pits are left undisturbed initially for a period of 15-20 days.
• Filled with top soil mixed with manures and fertilizers @ 20-25 kg FYM, 2 kg
bone meal and 300 g muriate of potash per pit.
Planting • Square system of planting is usually followed.
• A small hole is made at the centre of the pit and the desired material is planted.
Water is applied immediately after planting

Above 10 60 3.5 2.25 0.60

14. Methods- Basin or ring system of irrigation is recommended.
Two irrigations at an interval of 45 – 60 days during winter months
is required for bearing litchi trees.
The trees are irrigated from flowering onwards until the completion
of the post-harvest flush.
However, the growers normally irrigate the tree at 7 to 10 days
interval from panicle emergence to fruit harvest or until the post-
harvest flush appears
Irrigation

15. Intercultural Operations
Mulching- The farmyard
manure, compost or straw may
be used for soil mulching.
Cutting down of tall growing
weeds in the orchard and
spreading them over the soil is
another method of mulching the
soil.
Training & Pruning- After
planting, a certain amount of
pruning is often necessary to
give proper shape to the litchi
plant
Once the desired shape is
achieved, no pruning is usually
necessary, except the removal
of dead or diseased branches

16. Weed control
Weeds compete with the trees for water and nutrients.
Mulches used include wheat, barley or rice straw, hay,
sorghum stubble and similar materials.
Reduce costs by growing mulch material between the rows
for later slashing.

17. Maturity index
colour change to deep red
flattened of tubercles
smoothening of epicarp
Stages of maturity

18. Harvesting
 Depending on the tree age there are four
growth phases in litchi plants
 young non-bearing stage (1-3 years),
 young bearing stage (6-10 years),
 junior adult bearing stage (11-20 years)
 senior adult bearing stage (21 years and
above).
 Harvesting is usually done in May and June.
 The fruits are harvested in bunches along with a portion of the branch
and a few leaves.

19. 80-150 kg fruits/tree.
Storage temp:- 0 -1 °c with 80-85% RH.
Stogae life:- 3-4 weeks.
Grade used in litchi:-extra class, grade-I, grade-II.
