Plant biostimulatory effects of the green alga Chlorella sp. MACC-360, the Kocuria rhizophila FSP120 bacterial strain, and the combined inter-kingdom co-culture of the alga and bacterium were investigated using Solanum lycopersicum as a model plant grown under controlled greenhouse conditions. The application of algal–bacterial co-cultures using the soil drench method significantly improved plant growth parameters, vegetative biomass yield, fruit yield, and photosynthetic performance of the tomato plants. The combined treatment resulted in a 43.7% increase in mean fruit yield, while individual applications of K. rhizophila FSP120 and Chlorella sp. MACC-360 enhanced yields by 30.85% and 19.44%, respectively. Although total yield increases did not reach statistical significance due to high intra-group variability, the treatment’s efficacy was statistically confirmed through key yield parameters including significantly higher fruit weight and fruit diameter (p < 0.05). The enhanced specific biostimulatory effects of the combined treatment could be at least partly attributed to the increased level of algal extracellular polymeric substances (EPS), which was a specific effect of algal co-cultivation with a Kocuria rhizophila bacterium. Detailed analysis of plant phenotypic alterations, biomass yield, fruit and flowering parameters, as well as microbial community analysis of the rhizosphere, were conducted and compared among the various treatments. Our results indicate that an appropriately chosen combination and application of biostimulatory microbes can significantly enhance crop production, which might contribute to more sustainable agriculture.
