The development of biologically derived agricultural inputs is of interest for improving plant performance while reducing reliance on conventional chemical inputs. This investigation evaluated a formulation containing Spirulina platensis biomass and extracts of selected cruciferous vegetables. S. platensis was grown in Zarrouk’s medium, while aqueous extracts were prepared from radish (Raphanus sativus), broccoli (Brassica oleracea var. italica), cabbage (Brassica oleracea var. capitata), cauliflower (Brassica oleracea var. botrytis), and turnip (Brassica rapa). Equal portions of the vegetable extracts were combined with Spirulina biomass and a commercial bioenzyme to obtain the test formulation. The preparation showed complete solubility after dilution and a reported pH of 6.4–6.8. Its antibacterial activity was examined by disc diffusion against the selected bacterial strains. The combined vegetable extract produced inhibition zones as large as 18 mm against Staphylococcus aureus and Bacillus subtilis. Plant-growth observations further showed greater reported shoot and root lengths in treated mustard, sunflower, and fenugreek plants than in the corresponding controls. Molecular docking generated reported binding-affinity values between −9.0 and −4.4 kcal/mol. These observations suggest that the Spirulina–vegetable formulation merits additional experimental assessment as a biofertilizer and foliar treatment.
