This presentation is done by Export Agriculture students of Uva Wellassa University of Sri Lanka as a requirement for the subject which is “Fruit & Vegetable production”. Note that the information included here is relevant to Sri Lankan condition.

2. O Brinjal (Eggplant)
O Family: Solanaceae
O Botanical Name: Solanum melongina L

3. O It covers second large extent after curry banana
O hardy plant compared to other vegetables grown in Sri-
Lanka,
Grown in very dry areas under rain-fed conditions
or with minimum irrigation facilities
O can be kept for more than one year in production by
pruning at the end of the harvesting season
O This crop can be grown through out the year in all Agro-
climatic regions except up country-wet zone

4. O Grows well up to an elevation of about 1300m
O low country wet zone, Intermediate, up country
intermediate and dry zone
O Eggplant is tolerant to drought
 Well drain
 pH of 5.5-5.8 are more suitable
O The fruit color varies from pure white to dark purple or
black in different varieties

7. O The national average yield of brinjal - 7.38 t /ha
in Sri Lanka
O The national average yield in world - 13.7 t/ha
and 12.3 t / ha in Asia

8. Recommended Varieties
O Anjalee (F1 hybrid)

9. O Flowers are purple in colour
O Anthocyanin deposited in ribs
O Purple coloured fruits; Resistance to Bacterial Wilt
O Most applicable for wet and dry zones
O Fruit weight is about 80-110g and 20 cm in length
O Yield 30 -40 tons/ Ha with irrigation facilities

10. Amanda ((F1 hybrid)

11. O Flowers are purple in colour and high number of flowers
O Leaf blades are purple mixed green in colour
O Anthocyanin moderately deposited in ribs
O Fruit weight is about 75-100g and 15 cm in length
O Cylindrical shape, purplish pink colour fruits
O Moderately resistant to bacterial wilt
O Yield 30 -35 tons/ Ha with irrigation facilities

12. SM- 64

13. O Anthocyanin moderately deposited in stem
O Flowers are light purple in colour
O Moderately resistant to bacterial wilt
O Most applicable for wet and dry zones
O Cylindrical shaped, light purple colour, medium sized
fruits
O Yield 15-18 tons/ha with the irrigation facilities

14. Thinnavelli Purple

15. O Cylindrical shaped, dark purple fruits,
susceptible to Bacterial Wilt
O Anthocyanin well deposited in stem
O Leaf blades are purple mixed green in colour
(bright dark purple)

16. Padagoda (BW 11)

17. O Flowers are light purple in colour
O Stem and ribs are in green colour
O Resistant to bacterial wilt
O Cylindrical shaped; the fruit has light purple lines
on a white background
O Anthocyanin moderately deposited in stem
O Most applicable for wet and intermediate zones

18. Nursery Management
O Direct seeding is not practiced due to the small size of
the seeds
O Twenty nursery beds of 3x 1 m are required to raised
seedlings for 1 ha
O Soils should be worked to a fine tilth
O height of 15-20cm
O Incorporate well decomposed organic matter at the
rate of 3-4 kg/m2

19. O Sterile seedbeds by burning (straw and paddy husk)
O Treat seeds with a recommended fungicide such as Captan
or Thiram at the rate of 2g/100g of seed
O Seed should be planted in beds
10-15 cm apart
depth of 0.5 to 1 cm and cover with a thin
layer of soil
O Spread a layer of straw mulch over beds and water daily

20. O Remove the mulch when the germination is complete
O Avoid exposure to heavy rains and to prolong sunlight
O Harden seedlings ,exposing them to sunlight and
increasing irrigation intervals for one week before
planting
O Seedlings are ready to transplant after 21 days
O Seed Requirement: 250 g/ha

21. Time of planting
O Maha- November and December
O Yala- April to May
O (Avoid planting during heavy rains)
O Nursery should be laid one month before
planting

22. Land preparation
O Plough the field to a depth of 15-30cm
O prepare Planting holes - 30 x 30 x 30cm
O Incorporate organic matter - 6-12t/ha
O Level the area
O Establish drains across slopes to ensure good
drainage
O Avoid field cropped with Solanaceous crops in
the previous season Bacterial wilt

23. Planting and Spacing
O Optimum spacing is 90 x 60cm with one
plant/hill
O transplanting,
OHealthy seedlings aged 25 to 30 days
O four fully expanded leaves
O ransplant in the evening to avoid mid day wilt

25. Major Disease
O Damping off
O Bacterial wilt
O Foot Rot
Damping Off
 Causal Agents:
 Fusarium spp
 Pythium spp
 Phytopthora spp
 Rhizoctonia spp

26. O Seed treatments will effectively control this disease
O Eg: Captan
O Thiram
O Chlorothalonil
Bacterial wilt

27. Insect Pests
O Mites
O Hoppers

28. Harvesting
O Harvesting about 75 days after transplanting
O Ten to twelve picks at weekly intervals are
possible
O Yield can be varied with the variety and
climatic condition
O Main crop - 20-25t/ha
