PPMs, PGPB and Microalgae as Three Distinct Biofertilizers on Lettuce Health

The utilization of biofertilizers has emerged as a promising approach in modern agriculture to enhance crop productivity and quality while promoting environmental sustainability. In this study, we investigated the efficacy of three distinct biofertilizers, namely Potential Plant Probiotic Microorganisms (PPMs), Plant Growth-Promoting Bacteria (PGPB), and Microalgae, on the health on lettuce ( Lactuca sativa L. var. Crispa ). The experiment was conducted in a controlled environment of a high tunnel greenhouse at Gebze Technical University. The study encompassed a comprehensive analysis of various growth parameters, including plant height, stem diameter, leaf count, plant weight, root length, and chlorophyll content related with plant health. Our findings demonstrate that the application of PPMs, PGPB, and Microalgae biofertilizers significantly improved lettuce yield and quality compared to traditional fertilization methods. Moreover, these biofertilizers positively influenced soil and plant health, contributing to enhanced microbial diversity and soil structure. Additionally, our study highlights the environmental and economic benefits associated with biofertilizer usage, paving the way for sustainable agricultural practices. Overall, this research underscores the potential of PPMs, PGPB, and Microalgae biofertilizers as effective alternatives in lettuce cultivation, offering promising prospects for future agricultural innovations and practices.
