Quality attributes of eggplant varieties grown under different fertilization regimes

Abstract

Eggplants is an excellent nutritionally vegetable in all parts of the world, and it is extensively consumed, thus it has a considerable impact on the horticultural industry. The purpose of this study was to assess the qualitative of Two hybrid varieties (Mirval and Black Pearl) cultivated under various fertilization and farming regimes, with a focus on nutritional and antioxidant capabilities. The experiment was carried out on the farm of the Iasi University of Life Sciences in Romania, utilizing different agronomic techniques. A total of 8 version were cultivated using four different fertilization treatments: organic, chemical, control, and biological. Following harvesting, analyses were performed at the Andalusian Institute in Cordoba, Spain, using advanced laboratory modern. Quality and safety markers such as chlorophyll a, chlorophyll b, lycopene, beta-carotene, tannins, total polyphenols, and antioxidant activity (ABTS, DPPH assays) were assessed. The results showed significant variations between fertilization procedures. For example, the biofertilisation treatment produced the highest total polyphenol content, but the control group demonstrated modest antioxidant activity. Chlorophyll levels and carotenoid content also varied with cropping methods, demonstrating that fertilisation types had a significant impact on eggplant quality. This study examines the effects of planting schemes and irrigation regimes on the nutritional and phytochemical properties of eggplant, promoting sustainable agricultural methods that improve crop quality.
