Eggplant is a long-duration crop and applying NPK fertilizer during the growth (3 and 6 weeks after transplanting) and harvesting periods (every 2-3 weeks) is needed. Irrigation is essential in areas with little rain during the growing and fruiting stages. Avoid using land that was previously planted with solanaceous crops such as potato, tomato, pepper, etc. From flowering to market-fruit size takes about 3-4 weeks. Firm and heavy fruits should be harvested while they are still glossy with a desirable color.
