VEGETATIVE BEHAVIORS AND PRODUCTIVITY OF PEPPER AFTER APPLICATION OF PLANT GROWTH PROMOTING MICROORGANISMS
N. Panayotov, K. Sapundjieva, M. Naydenov, Y. Kartalska
Abstract: The main purpose of the carried out pots experiments was to establish the vegetative development and productivity of pepper plants Kurtovska kapia 1619 and Bulgarian rotund varieties when they are cultivated in an substrate, inoculated with PGPM (Plant growth promoting microorganisms). The bacteria strains Bacillus subtilis A1 and Pantoea agglomerans B43, and the fungi strain Trichoderma viride T6, in concentrations of 50, 100 and 150 ml were used. The microorganisms were applied six days after the seeds planting. The general vegetative weight, the weight and volume of the root system, height, weight and
diameter of the stem, number and weight of leaves, number of flowers, and number of fruits were monitored. The total yield per one plant was recorded. The highest growth of the root system and stem were observed under the effect of Trichoderma viride T6 – 50 ml, and for the leaves and flowers, after the inoculation of Bacillus subtilis A1. The number of formed fruits also increased. The productivity of Kurtovska kapia 1619 is highest after the application of 150 ml of Bacillus subtilis A1, and of Bulgarian rotund – of 100 ml Trichoderma viride T6.
