Fertilization and Pre-Sowing Seed Soaking Affect Yield and Mineral Nutrients of Ten Microgreen Species

Microgreens, vegetable or herb seedlings consumed at a young growth stage, are considered to be functional food with high concentrations of mineral nutrients and healthy beneficial bioactive compounds. The production microgreens has been increasing in recent years. Vegetable growers interested growing as new specialty crop due their market value, popularity, short cycles. However, there is lack research-based crop-specific recommendations for cultural practices including fertilization, pre-sowing seed treatments, effects on nutritional facts microgreens. Ten microgreen species were evaluated shoot nutrient affected by one-time post-emergence fertilization soaking two repeated experiments, from November 2018 January 2019, greenhouse. varied fresh dry weights, height, visual rating, well macro- micro-nutrient concentrations. Fertilization general-purpose soluble fertilizer (20-20-20 micronutrients) rate 100 mg·L−1 nitrogen (N) increased weight, one both the exception decreasing calcium (Ca), magnesium (Mg), manganese (Mn). Seed consistently decreased weight when was significant effect.
