APPLICATION OF MICROBIAL FERTILIZERS IN THE HYDROPONIC CULTIVATION OF GINGER (ZINGIBER OFFICINALE)
Keywords:
Hydroponics, microbial fertilizers, ginger, sustainable agricultureAbstract
This study investigates the effectiveness of microbial fertilizers, specifically
humic substances and Pseudomonas fluorescens, in cultivating ginger (Zingiber officinale) under
a substrate-based hydroponic system. Elm bark was used as the substrate, and the experimental
group was compared with a control group using mineral fertilizers. The results demonstrated that
microbial fertilizers significantly enhanced plant growth parameters, including plant height, leaf
number, rhizome weight, and length. The findings suggest that microbial fertilizers can serve as
an eco-friendly and sustainable approach for ginger cultivation in modern agriculture.
