Characterization of Culturable Promoting Yeast and Fungi from Takakura Compost
Compost has an important ecological role in increasing soil fertility, plant growth and
sustainable agriculture, especially in recycling organic waste. This research characterizes the role of
Plant Growth Promoting Fungi (PGPF) derived from Takakura compost and analyzes the influence of
microbial communities on saga plants (Abrus precatorius). Takakura Compost is an alternative
because of its simplicity and effectiveness in supporting beneficial microorganisms to facilitate the
decomposition of organic materials. PGPF, including fungi and yeast, plays an important role in plant
health and growth, increasing nutrient absorption, producing growth hormones in plants, and
increasing resistance to environmental stress and pathogens. The PGPF microbial community in
compost positively influences plant growth by improving soil structure, nutrient availability, and
overall soil health. Using inoculation methodology, this study characterized fungi and yeasts from
Saga plant compost and soil, demonstrating the significant impact of microbial diversity in compost
on Saga plant growth. Compost rich in PGPF significantly increases the growth of Saga plants by
increasing the number of leaves and plant height, while increasing the diversity of soil microbes. The
study also explores how compost affects soil microbial communities, contributing to a more resilient
and diverse soil ecosystem. This research provides important insights into the role of PGPF in
promoting plant growth and enhancing soil microbial communities, with implications for sustainable
agricultural practices.
