Brinjal is propagated by seeds. Brinjal seeds are dicotyledonous.
Collecting Brinjal fruits from plants
To start with, collect the seeds from open-pollination varieties of Brinjal. Pollination by wind, insects, or other natural means is called open pollination. Hybrid seeds won't work. Ask for open-pollinated varieties in the nursery or check the label before buying the seeds.
When collecting Brinjal seeds, grow only one type of Brinjal in an area. If you plant different varieties together, the plants can get cross pollinated.
The flower drop is a common problem in Brinjal. It may be due to failure to self-pollinate. To increase the percentage of pollination, encourage pollinators in the garden and do not use chemicals that are harmful to pollinators. Also, lack of humidity may cause flower drop.
Collecting Brinjal Seeds
Wait until the Brinjal is overripe before collecting eggplant seeds. Overripe Brinjal looks brownish to back or yellow, and they look shriveled. Slice open such ripe brinjals and remove the seeds from the pulp. Collect the seeds and wash the pulp away. Dry the cleaned seeds in the shade.
Storing the seeds
Ensure the seeds are properly dried before you store them. Put the seeds in an air-tight jar or a zip-lock bag. Store the seeds in a cool, dry place out of the direct sun with a humidity of 20-40%.
Brinjal crop can be grown in both winter and summer. As a winter crop, it is better to sow Brinjal between June and July. And as a summer crop, it is recommended to sow Brinjal between December and January.
How to sow brinjal seeds?
Brinjal seeds are tiny and should be sown at a depth of 2-3 cm and covered with a thin layer of soil. After sowing, irrigate lightly. You can cover the beds with dry leaves or grass to maintain the required temperature and moisture. Light watering should be done regularly. Eggplant seeds germinate in 7 to 14 days, depending on the heat, moisture content, and age of the seed. Remove the dry leaves or grass on the seed beds when you see the signs of germination.
Just before transplanting, the seedlings can be hardened by slightly withholding water. Then, the seedlings can be transplanted to a container or ground after 4-6 weeks when the plant has grown 15cm tall with 2-3 true leaves.
Soaking the seeds in water for up to 24 hours increases the chances of seed germination and the speed of germination.
How long will it take for the plant to reach the harvesting stage?
You can harvest brinjal 65 to 80 days after transplanting. It may take 100-120 days for the seed to germinate, grow and reach the harvesting stage.
