Abstract
Microgreens are forms of production and consumption of plant foods in their early growth phase that add maximum efficiency to the production process. The use of this crop has been used in large urban centers, in places with low luminosity, being the main problem was the choice of an adequate source of lighting for the production of microgreen in vertical urban farms. The objective of this work was to evaluate the use of different sources of artificial lighting with LED in the indoor production of arugula (Euruca sativa) microgreen. Six treatments were evaluated, namely: 1. Three 50w cold white Led boards (3BF), 2. Three 50w warm white Led boards (3BQ), 3. Three 50w full spectrum Led boards (3FS), 4 Two 50w full spectrum Led boards, and one 50w cold white Led board (2FS + 1BF), 5. One 50w full spectrum Led boards, one 50w cold white Led board and one 50w warm white Led board (FS + BF + BQ), 6. For ambient lighting (Control), the parameters analyzed were Fresh weight of shoot (FWS in g) and Dry weight of shoot (DWS in g). The use of different artificial lighting sources with LEDs increased the mass production of indoor cultivation of arugula microgreens, which demonstrates greater efficiency for plant growth, with the sources (3BQ), (3BF), and (1FS + 1BF + 1BQ), showing the best result in the development of arugula microgreens, thus generating greater aerial part mass in plants.
