The study found that biofertilizers significantly improve cucumber growth and reduce the number of soil-borne pathogens. Different biofertilizers have different effects on soil microbial communities, which leads to changes in microbial diversity and taxonomic structure during different growing seasons. The use of biofertilizers allows for cost-effective continuous production of high-quality crops from the same soil each year, while controlling soil-borne diseases.
Reductions in the quality and yield of crops continuously produced in the same location for many years due to annual increases in soil-borne pathogens. Environmentally-friendly methods are needed to produce vegetables sustainably and cost effectively under protective cover. We investigated the impact of biofertilizers on cucumber growth and yield, and changes to populations of soil microorganisms in response to biofertilizer treatments applied to substrate or soil. We observed that some biofertilizers significantly increased cucumber growth and decreased soil-borne pathogens in soil and substrate. Rhizosphere microbial communities in soil and substrate responded differently to different biofertilizers, which also led to significant differences in microbial diversity and taxonomic structure at different times in the growing season. Biofertilizers increase the prospects of re-using substrate for continuously producing high-quality crops cost-effectively from the same soil each year while at the same time controlling soil-borne disease.
