VIEWS: times Release Date:2020-06-22

The characteristics of eggplant are flowering, fruiting and continuous harvesting. The peak of nutrient demand appears in the fruiting period. In this period, in order to coordinate the contradiction between reproductive growth and vegetative growth and prevent the premature senescence of plants, it is necessary to supplement nutrients in time after harvest.

Every 1000kg eggplant needs 3.2kg nitrogen, 0.94kg phosphorus pentoxide and 4.5kg potassium oxide. From seedling stage to early fruiting stage, eggplant needs the most nitrogen, and at the peak of fruiting stage, it needs the most potassium. In addition, it needs some trace elements such as calcium, magnesium, boron and zinc.
