Growth of Creeping Bentgrass after Applying Microbial Fertilizer Containing Lactobacillus plantarum
2023
Kim, Y.S.
This study was conducted to evaluate the effects of microbial fertilizer containing Lactobacillus plantarum (MF) on the growth and turfgrass quality in the creeping bentgrass ‘Penn A-1’ with visual turfgrass quality, chlorophyll content, clipping yield, nutrient content and its uptake amount. Treatments were designed as follows; no-fertilizer (NF), control (3N g m⁻² month⁻¹), MF-1 (control + 1 mL m⁻² time⁻¹), MF-2 (control + 2 mL m⁻² time⁻¹), MF-3 (control + 4 mL m⁻² time⁻¹) and SF (control + sterilized MF 2 mL m⁻² time⁻¹). Compared with control, visual turfgrass quality, chlorophyll content, nutrient content and uptake amount of MF treatments were not a significant difference. After applying MF, the clipping yield of MF treatments increased by 164-181% than that of NF, and by 15.3-22.9% than that of control or SF. These results indicated that the application of microbial fertilizer containing L. plantarum improved turfgrass growth by prompting nitrogen uptake in the creeping bentgrass.
