Fresh weight of shoot (mg/shoot), fresh yield (kg/m2), dry biomass (g/m2), and chlorophyll, carotenoid, and nutrition element content of microgreens were measured. Estimated daily intake (EDI) of macro- and microelements of microgreens was calculated.Findings: While the highest mean fresh weight of shoot of L. sativum microgreens was measured as 27.65 mg/shoot in media of C50, the highest fresh yield and dry biomass of microgreens were measured as 1.870 kg/m2 and 94.81 g/m2 in media of WE50. Chlorophyll a content of microgreens cultivated in C100, C25, and WE100 was significantly lower than control (P KW - compost KW - water extract KW - microgreens KW - Lepidium sativum KW - nutrition elements N2 - Amaç: Bu çalışmanın amacı kompost, kompost sulu ekstraktı ve torf ile yetiştirilen Lepidium sativum mikroyeşilliklerinin verim, klorofil ve karotenoid içeriğini ve besin profilini değerlendirmektir.Metod: Kontrol (100% torf), C100 (100% kompost), C50 (50% torf + %50 kompost), C25 (75% torf + %25 kompost) ve komposttan elde edilen WE100 (100% sulu özüt), WE50 (50% sulu özüt) ve WE25 (25% sulu özüt), L. sativum mikroyeşilliklerinin LED ışık kaynağı altında yetiştirilmesi için kullanılmıştır. Mikroyeşilliklerin taze sürgün ağırlığı (mg/sürgün), taze verimi (kg/m2), kuru biyokütlesi (g/m2), ve klorofil, karotenoid, ve besin elementi içeriği, ölçülmüştür. Makro ve mikro elementlerin tahmini günlük alımları hesaplanmıştır.Bulgular: L. sativum mikroyeşilliklerinin en yüksek taze sürgün ağırlığı 27.65 mg/sürgün olarak C50’de, en yüksek taze verim ve kuru biyokütlesi sırasıyla 1.870 kg/m2 and 94.81 g/m2 olarak WE50’de ölçülmüştür. C100, C25, ve WE100’de yetiştirilen mikroyeşilliklerin klorofil a içerikleri kontrole kıyasla sırasıyla P CR - [1] Pinto, E., Almeida, A. A., Aguiar, A. A., & Ferreira, I. M. P. L. V. O. (2015).
