INFLUENCES OF PLANT DENSITY AND SEEDLING PLANTING DATES ON CABBAGE (BRASSICA OLERACEA VAR. CAPITATA) SEED PRODUCTION EFFICIENCY

Cabbage (Brassica oleracea var. capitata) is a prevalent vegetable crop cultivated for its nutritious leaves, which have a variety of culinary and medicinal use. As a consequence, vegetables such as cabbage are extremely popular among consumer demands. Constraints in the seed production chain highlight the significance of seed germination and crop`s growth at the farm level. The production of high-quality seeds is a crucial step in this crop`s cultivation since it impacts the success of germination and plant growth. In this study, we aimed to investigate the influence of plant density and seedling planting dates on cabbage seed process performance. This research is a component of a larger project aimed to devise a comprehensive and new modernized strategy for cabbage seed production. The experiment was carried out on `Silviana` autumn cabbage variety during two growing seasons, a field trial was undertaken to assess three plant densities (low, medium and high) and three seedling planting dates (early, mid-season and late). Cabbage seeds were also subjected to a range of seed viability and vigour tests.
