S. Solanum
Introduction Eggplant (Solanum melongena) is a species of nightshade commonly known in British English as aubergine and also known as melongene, garden egg, or guinea squash. It is known in South Asia as brinjal. It bears a fruit of the same name (commonly either "eggplant" in American and Australian English or "aubergine" in British English) that is widely used in cooking, most notably as an important ingredient in dishes such as moussaka and ratatouille. As a member of the genus Solanum, it is related to both the tomato and the potato. It was originally domesticated in India and Bangladesh from the wild nightshade, the thorn or bitter apple, S. incanum.

Crop Management
Soil
Eggplant can be grown in sandy to very clayey soils. Best results however are obtained in soils with a medium texture, deep, rich in organic matter good moisture retention and well drained. Eggplant does not tolerate waterlogging. Before preparing the soil samples should be taken from both the top soil layer (0 – 20 cm) and the subsurface layer (20 – 40 cm) which is essential for the proper fertilization application. Soil preparation usually consists of one to two plow passes and two disc passes. Plowing should reach a depth of 30cm followed by a harrow to level the soil. Next limestone should be applied evenly by hand followed by a second plowing to homogenously incorporate the limestone in the top soil layer (0 – 20 cm). Liming should be done 60 to 90 days before transplanting for dolomitic limestone (dolomitische kalksteen) while 15 days for calcined limestone (gecalcineerde kalksteen) and soil should be kept humid. The amount of limestone to be applied depends on the results of your soil analyses. There are two
methods for calculating how much limestone should be applied to maintain a soil pH of 5.0 to 6.5 with a
70% degree of base saturation:
Mton/ha-1 =
(V1 – V2)T
CLP
1) Mton/ha-1 = Metric tons of limestone per hectare
2) V1 = actual degree of base saturation (soil analyses) = [(Ca2+
+ Mg2+
+ K+) x 100]/T
3) V2 = 70% (desired degree of base saturation)
4) T = Cation exchange capacity at pH 7.0 per dm3 CEMOLC/dm3 = [Ca2+
+ Mg2+
+ K+ + (H + Al)]
(Calculating CEMOLC/dm3 based on soil analyses)
5) CLP = Corrected Lime Potential
The cultivation of Eggplant should be done in grooves or pits. Grooves need to be 20cm deep and 0.7 to
1.0 meter wide while the beds should have a width of 1.2 to 1.5 meters. The larger spacing should be
applied when using hybrid cultivars, which are more vigorous or when you want to prolong the harvest
period.
Chemical Fertilizer needs and sidedress:
There are two methods for deciding on how to fertilize eggplant. The first is for small scale farming where the added costs of soil analyses can be a burden and the latter is for a larger scaled approach where the added preparation costs can lower the overall production costs.
1) Eggplant is a very tender annual. And a heavy feeder use 15 milliliter of ammonium nitrate 33-0-0 per 3 meter row. Before planting, broadcast (1.5kg). 10-10-10 per 30m². Use a starter solution on transplants. Use O.5 kg 10-10-10 per 30m² - 3 to 4 weeks after planting and repeat in one month if needed. When fruits are swelling, apply a high potash tomato fertilizer.
2) Fertilization for Eggplant should be done using the fertilization chart based on the results gained through a soil analyses. The complete dosage of P (100%) and a portion of the K and N (40%)
5
should be applied before transplanting. De remaining dosage should be applied during the entire cultivation period at 10% every 15 days. In addition 20 to 40 Mton/ha of cattle manure or 5 to 10 Mton/ha of chicken manure should be applied and well incorporated in the pits or groves where the rows shall be placed 10 to 15 days before transplanting. Use the larger amounts for sandy soils.

It is not always easy to find fertilizers that can easily fulfill the required fertilizer needs of a soil. For that reason it is recommended to use a fertilizer calculator to calculate how much based on the availability of fertilizer mixtures (Ex. 10-10-10, 30-0-0, etc.) near you. http://soiltesting.tamu.edu/calc2/AgNcalc.htm
Sowing eggplant
When growing your eggplant from seed, give your eggplant a head start by planting your eggplant seeds in a controlled environment about 4 weeks prior to transplanting. Eggplant seeds are fairly small so try not to plant your eggplant seeds more than six millimeters deep. Under optimal conditions, your eggplant seeds should germinate in as little as 7 days. Do not permit seedlings or young plants to suffer from low temperature or drought.
Eggplant seeds will germinate well for the better part of four years or more when stored properly in
a cool, dry location.
6
Transplanting
Plants should be grown for eight to ten weeks in 5cm or larger pots before setting them out. During this period plants should not be in direct sun light and should as they grow be gradually exposed to direct sunlight in the morning and evening so they can harden and get ready for transplanting. Also during this perio less water should be given to the young plant so branches can get woody and the plant can strengthen itself in general. Once you are ready to move your eggplant to the outdoors, make sure you choose a sunny location (full sun works best) where the soil has a pH level of 5.5 to 7.0 (acidic to neutral). Space out your eggplant 45 centimeters and 60 centimeters between rows. The soil where the transplants will be put and the soil in the seed tray or pots should be sufficiently moist to avoid root damage. Place transplants in the soil slightly deeper than they were in their pot. Avoid placing transplants such that the part where the stem meets the root is buried. Cold soil will shock the plant and set it back several weeks. Press the soil around the plant slight to increase the contact between the soil and root system. Aubergines are suitable for growing in large containers or tubs. Container growing will help prevent soil borne disease.
Crop Rotation
When rotating, eggplant will do well following beans or peas.
Inter-cropping
In companion planting, eggplant fairs well with beans, peas, and peppers, but not so well with fennel.
Pollination - Hand pollination
The flowers are relatively unattractive to bees and the first blossoms often do not set fruit. Hand pollination will improve the set of the first blossoms. Flowers are complete, containing both female and male structures, and may be self-pollinated or cross-pollinated. When pollination is needed on a large scale, such as for field crops, orchards, or commercial seed production, honeybees or other pollinators are cultured and provided for pollination management. Hand-pollination is an option only on a small scale, but is a common technique by gardeners that transfer pollen with an artist brush or cotton swab. The flowers on these plants can stay open for several days, so it's not a bad idea to repeat the process every day or so. You will know the process has worked if the flower closes but doesn't fall off the plant.
Sometimes the corolla is removed from male flowers and the flower itself is brushed against the stigmas of female flowers. Keep in mind though, that every "perfect" flower is female, so it can produce fruit. Every flower you pull off for pollinating is a fruit you can't harvest.
A potential cause of your eggplant failing to produce fruit is stress from lack of water. Has it been very hot and dry there? Are you watering adequately? Also, if it is very humid the pollen may stick and avoid falling down onto the pistil to pollinate the flower.
7
Harvesting
Eggplant can be cultivated for 12 months and harvesting should take place 2 times per week.
Also, as an eggplant fruit matures, the seeds become more noticeable. So an eggplant picked when very mature to over-mature might appear "seedier" than others picked when less mature, even those from the same plant. Pick eggplant fruits when full size is reached but while the exterior is still a glossy purple.
Once the exterior becomes dull purple, the eggplant fruit is over-mature. Depending on the size of fruit you wish to harvest, pinch out terminal growth and blossoms to allow up to 6 fruits to mature or allow all fruits to set and harvest when small. Male eggplants tend to have fewer seeds, and are therefore less bitter than female eggplants. To sex an eggplant, look at the indentation at the bottom. If it's deep and shaped like a dash, it's a female. If it's shallow and round, it's a male. Smaller eggplants also tend to be less bitter. Freshness is important, so don't store them for very long.
The ideal time to harvest fruits and vegetables is late in the afternoon, sorting them and packing them at dusk and carrying them at night and / or at dawn, offering fresh produce before sunrise. Avoid dewy mornings and rainy days. Harvested product should be placed immediately in the shade or be transported to the "packing house" shed or hanger. Use buckets, baskets or protected bagst (with false bottom. Always disinfect the materials used to harvest using a solution of sodium hypochlorite (bleach) in a concentration of 4 ml (for plastics) to 8 ml of the product to 10 liters of water (for wood materials)
Storing Eggplant
Eggplants are very perishable and become bitter with age. They should be stored in a cool, dry place and used within a day or two of purchase. To store in the refrigerator, place in a plastic bag. If you plan to cook it the same day you buy it, leave it out at room temperature. Eggplant is not suitable for drying or canning. Freezing is the best method for home preservation.
Another method that can be used to decide when to pick the fruit is to pick fruits when about 2/3 maximum size.
Mature fruit should not be left on the plant as this will reduce overall productivity.
8
Watering
Water Aubergine sufficiently to moisten the soil to a depth of at least 6 inches (15cm). The critical period for moisture is during fruit set and fruit development.
General Cultivation Practices
Eggplant fruits can become heavy for the plant to carry and may cause it to tip over. When tipping over the risk of the fruits touching the soil increases and so does the attack of insects. Use a stake to prop them up. When plants are about 20 cm high, nip back the growing tip to encourage branching. These heavy feeders should be planted in heavily composted soil with lots of manure, if available. Side dress frequently, especially when the plant begins to bloom. Aubergine is fairly drought tolerant and should not be over watered as it is susceptible to root rot. Mulching around the plant will help maintain even moisture. Watering may be increased when blooms appear.
Integrated Pests Management
Aromatic plants such as lavender, tansy, marigolds or wormwood help to keep aphids at bay. Pests: Aphids, red spider mites and caterpillars are the main culprits. Others are: colorado potato beetle, tomato russet mite, flea beetle, lace bugs, root knot, nematodes, thrips ,tomato hornworms, pepper maggot, whitefly. Diseases: Phytophthora Blight - Avoid water-logged root zones.
Grow Aubergine in well drained fields. Planting on raised beds will increase soil drainage. Water management is of primary importance for controlling Phytophthora blight. Rotate infested fields with other non-host crops for several years
Verticillium Wilt - Because of the aubergine's susceptibility to verticillium wilt, rotate plantings with other crops on the same garden soil. Avoid fields with a history of Verticillium Wilts. Fumigate soils with a propriety soil fumigant - 250 to 370lt per hectare Allow at least 30 days between application of the fumigant and planting.
Practice a 2 to 3 year crop rotation schedule to avoid Phomopsis Blight, Alternaria Leaf Spot, Cercospora Leaf Spot, and Anthracnose
Pests
Eggplant fruit and shoot borer (EFSB)
Leucinodes orbonalis Guenee (Lepidoptera: Pyralidae)
Eggplant fruit and shoot borer is one of the most destructive pests on eggplant and can reduce yields by as much as 70%.

Biology
Egg: The adult females lay eggs singly or in groups of two to five on the under surfaces of leaves (Plate 1), tender shoots, flower buds, or the base of developing fruits. Each female lays about 250 eggs, which are creamy white soon after laying, but turn red before hatching. The egg period is three to five days.
Larva: The larva is creamy white to pink in color in the early stages. The grown-up larva is pink with sparse hairs on the warts on the body and a dark brown or blackish head (Plate 2). The full-grown larva measures about 16-23 mm in length. The larva usually has five instars, sometimes six. The larval period is about two weeks in summer and three weeks in winter.
Pupa: The larva pupates on the plant parts or plant debris on the soil surface, or rarely, under the soil. The pupation occurs in tough silken cocoons (Plate 3), and the pupa is dark brown in color. The pupa measures about 13 mm. The pupal period varies from one to two weeks.
Adult:
The moth is white or dirty white with pale brown or black spots on the dorsum of thorax and abdomen (Plate 4). Wings are white with a pink or blue tinge, and have pink or brown and red spots on the forewings. The female is bigger than male, with a bulged abdomen. The female moth tends to curl its abdomen upwards. The adult life span is about a week; the females live longer than males.
Damage Symptoms
Upon hatching, the larva starts boring near the growing point or into the flower buds or fruits. During the early vegetative phase of the crop growth, it feeds on the tender shoots. Soon after boring into the shoots and fruits, the larva seals the entry hole with excreta. The larva tunnels inside the shoot and feeds on the inner contents. It also fills the feeding tunnels with excreta. This results in wilting of young shoots (Plate 5), followed by drying (Plate 6) and drop-off, which slows plant growth. In addition, it produces new shoots, delaying crop maturity.

During the early reproductive phase, the larva occasionally may feed on flower buds and flowers. However, it prefers to feed on the fruit rather than other plant parts during the fruiting stage of the crop. Damaged fruit exhibits boreholes on the surface (Plate 7), which often are sealed with excreta. The larva feeding inside the fruit creates tunnels filled with frass and fecal pellets (Plate 8).

Management Any single method of pest management alone will not achieve a level of EFSB control acceptable to producers. A simple and economic IPM technique can provide satisfactory control.
Avoid monoculture and follow crop rotation. Discontinuation of eggplant cultivation in a community for a few seasons will significantly reduce EFSB populations.
Avoid growing eggplant seedlings near fields with standing crops, in or near fields where the crop was grown previously, or near dried eggplant heaps. If seedlings must be grown in those areas, cover the beds with 30-mesh nylon net to prevent the entry of EFSB moths.
Choose resistant or moderately resistant cultivars available in the region. Consult the local extension agency for availability of resistant or tolerant varieties.
Promptly remove and destroy infested shoots and fruit at regular intervals until final harvest.
Protect parasitoids such as Trathala flavoorbitalis (Cameron), Eriborus sinicus (Holmgren), and Pristomerus testaceus (Morley). Reduced use of synthetic pesticides will enhance the activities of these natural enemies. In addition, weekly releases of egg parasitoid, Trichogramma chilonis (Ishii) @ 1g parasitized eggs/ha/week and larval parasitoid, Bracon habetor Say @ 800-1000 adults/ha/week could be followed (Alam et al. 2006a)
Install EFSB sex pheromone lures in traps at the rate of 100 traps per hectare. Place the traps either at canopy level or at slightly above the canopy level for effective attraction.

Classification The classification of fruits and vegetables has the following advantages:
A. Improves product presentation (better uniformity in size, color, packaging and the type); B. By offering a standardized product, package and credibility in volume and weight negotiation
and the business in general is simplified; C. Allows better option to the buyers; D. Reduces losses in marketing and prevents the marketing of unsuitable products. E. The classification gives more credibility and competitiveness to your product with the added
security of business and greater profit to the producer and the entire production chain.
UNECE STANDARD FFV-05 The united nations classification efforts puts more effort on allowing high quality produce in the
international market and focusing considerably on the cultivar, external quality and the end consumer.
