Discover key facts about brinjal nutrition, composition, and best cultivation practices in horticulture. This quiz covers important details relevant to growers, students, and enthusiasts.
Which vitamin is most abundant in brinjal (eggplant) according to horticultural nutrition studies?
Explanation: Vitamin C is the most abundant vitamin found in brinjal, supporting immunity and acting as an antioxidant. Vitamin D is not present in significant amounts in brinjal, Vitamin B12 is primarily found in animal products, and Vitamin A content is relatively low in this vegetable.
Brinjal is a good source of which essential mineral, important for proper cell and nerve function?
Explanation: Brinjal contains significant potassium, which is crucial for cell and nerve health. While it does have traces of iron and zinc, the levels are lower compared to potassium. Sodium is present only in minor amounts and not considered a nutritional highlight of brinjal.
How would you describe the caloric content of brinjal per 100g serving?
Explanation: Brinjal has a low caloric value, roughly 25 kcal per 100g, making it suitable for calorie-conscious diets. 'High', 'Moderate', and 'Very high' overstate its actual energy contribution and may mislead regarding its suitability for low-calorie diets.
What phytochemical in brinjal skin is primarily responsible for its deep purple coloration and antioxidant activity?
Explanation: Anthocyanins give brinjal skin its characteristic purple shade and have antioxidant benefits. Lycopene is prominent in tomatoes, beta-carotene provides orange coloring in carrots, and chlorophyll is responsible for green coloration, not purple.
To maximize brinjal's nutrient uptake, which soil condition is considered most beneficial during cultivation?
Explanation: Well-drained loamy soil supports brinjal's growth and nutrient uptake by providing balanced moisture and fertility. Saline, waterlogged, and highly acidic soils impede root health and hinder access to nutrients, leading to poor crop performance.
