Analysis of the growth and yield of Microgreens of the Brassica sp. family on the effect of limitied irradiation

Urban Farm DB summary

Conducted from February to March 2025 at the Faculty of Agriculture laboratory, Singaperbangsa University, Karawang, Indonesia, this study examined growth and yield of Brassica microgreens (cauliflower, radish, and broccoli) under six levels of limited light exposure (indoor control, outdoor control, and 60%, 50%, 40%, and 30% lighting), using a split-plot design within a group randomized design with two replicates per treatment (36 experimental units total). F-tests at the 5% significance level, followed by Duncan's Multiple Range Test, showed a significant interaction between light exposure and plant type for growth uniformity and plant height at 7 days after planting (DAP). The combination of 50% lighting with broccoli produced the highest growth coherence value, 88%, while the tallest plants at 7 DAP, 6.55 cm, occurred with 30% lighting combined with broccoli.
