The impact of sowing density on the productivity and growth dynamics of Ocimum basilicum grown as microgreens

The increasing interest in fresh, functional, and nutraceutical products has driven the demand for healthy and longevity-promoting foods, with microgreens gaining popularity due to their vibrant colors, delicate texture, and rich phytonutrient content. Among various microgreens, Ocimum basilicum is widely recognized for its aromatic, bioactive properties, and nutritional composition, making it a promising functional food. This study aimed to investigate the impact of sowing density on the productivity, growth dynamics, and quality of O. basilicum cultivated as microgreens, focusing on improving production efficiency. The experiment was conducted in November 2024 in a controlled environment with three sowing densities: 2.5 g/m² (control, C), 3.5 g/m² (T1), and 4.5 g/m² (T2). Key parameters such as seed germination, plant height, leaf area, and fresh yield were evaluated throughout the growth cycle. Results showed that higher sowing densities (T2) positively affected seed germination and plant height during the initial growth stages. Although initial growth was more vigorous in the control treatment (C), the differences between treatments became less pronounced over time. The study concluded that optimizing sowing density is crucial for maximizing microgreens yield and improving the overall sustainability of basil production, providing valuable insights for commercial growers.
