Brinjals is the nightshade Solanum melongena, also known as the aubergine, brinjal eggplant, eggplant, melongene, or guinea squash. It was domesticated in India. It grows 40 to 150 cm (16 to 57 in) tall, with large, coarsely lobed leaves that are 10 to 20 cm (4–8 in) long and 5 to 10 cm (2–4 in) broad.The young and almost mature fruits are used as a vegetable. The fruit is a good source of vitamin A and C, potassium, phosphorous and calcium. They may be roasted, fried, stuffed, cooked as curry or pickled. Cooking for prolonged periods will destroy most of the vitamins. In Kenya production is done throughout the year and the bulk of the crop is exported. The fruits of the white varieties have medicinal value for diabetics. Eggplant has a cropping period of 4-7 months. In Kenya they are normally planted from beginning of June to end of December to correspond with the export season from October to May.

Husbandry Eggplant is normally propagated by seed and also by rooting of healthy shoots. Soaking the seeds in water for 24 hours speeds up germination. Transplant by digging a hole deep enough to bury a plant so that its first true leaf is just above the soil surface. Irrigate furrows immediately after transplanting. Side dressing with groundnut cake is recommended 40 days after transplanting. Also at this period, remove three nodes at the tips of the plants to improve branching and to increase the number of fruits. Weed control should be shallow, to avoid damage to the roots. Tall-growing cultivars will also require support. Mulching with dried plant materials reduces moisture loss and weed problems.

Expected Duration from Planting to Harvesting 2.5 – 3.5 months
Climatic Conditions Optimum day temperatures are 25-35°C and night temperatures from 20-27°C. It does not tolerate frost. It is tolerant to drought and excessive rainfall. It does best in well-drained, sandy loam soils and lowland (below 800m) areas with relatively little temperature variation. The pH requirements range from 6 to 7 with the optimum being pH 6.4.
Harvesting The first harvestable fruits appear 60-90 days after planting. Harvest fruits when they are about two-thirds of their maximum size. Harvesting is done once or twice a week by cutting the fruit from the stem and leaving a short piece of stem on the fruit. For seed production, harvest only fully mature fruits from healthy and productive plants.
Post Harvest and Storage Egg plants are stored in cool spaces. During transportation, ensure the fruit is not injured.
