Abstract
The efficacy of the bacterium Bacillus subtilis no. 2 and humic preparation Stimulife on yield and fruit formation in sweet pepper (Capsicum annum L.) was studied using the technologies with their separate and combined applications. The application of Bacillus subtilis no. 2 was shown to decrease the coefficients of variation in the leaf and fruit masses of pepper plants. The maximum directional effects of the above preparations were revealed by graph analysis. The effects of Bacillus subtilis no. 2 and HP Stimulife are focused on increasing the number of leaves on pepper plants and decreasing the vegetation period of the plants, respectively; their joint effect is focused on increasing the number of fruits on a single plant. Factor analysis has shown that the combined use of Bacillus subtilis no. 2 and HP Stimulife has a negative synergistic effect on chlorophyll (a + b) and growth duration. The varieties of pepper plants exhibited different responses to the above preparations. It has been concluded that the humic preparation, in addition to a direct effect on plants, can also manifest its physiological activity indirectly through the activation of auxin synthesis by PGPR bacteria associatively related to plants.
