INFLUENCE OF SPIRULINA PLATENSIS ON GROWTH OF CHINESE CABBAGE AS A BIOSTIMULANT
Abstract
In this article products derived from a blue-green microalgae filtrate of Spirulina platensis (used for seed soaking and foliar spray) were tested in the cultivation of microgreen Chinese cabbage or bok choy or Brassica rapa spp chinensis. The effect of shoot length, root length, multielemental composition was studied using inductively coupled plasma-optical emission spectrometry, multielemental analyses of algal products and chinese cabbage were conducted inductive coupled plasma optical emission spectrometry (ICP-OES). The best soaking time and concentration of filtrate were established. As a foliar spray, 15% filtrate has been used. The algal products used enhanced the element content of seedlings. The collected results demonstrated that algal extracts have a strong potential for use in modern horticulture and agriculture. The use of Spirulina-based products promotes the use of sustainable agriculture to ensure adequate food production to meet the needs of a growing population while also preserving the environment.
