Frontiers in Plant Science · 2026

Key Findings

01Organomineral fertilization (G5) maximized essential oil yield.
02Organomineral fertilization (G5) maintained higher mean rosmarinic acid content compared to the control.
03Fertilization treatments significantly affected all measured parameters (herbage yield, essential oil yield, and rosmarinic acid content).

Application

Design takeaway

When sourcing or cultivating medicinal plants, consider the specific nutrient management strategies employed, as they can dramatically influence the concentration of active compounds.

How to apply

When designing products that utilize Melissa officinalis L. or similar medicinal herbs, specify or investigate the fertilization methods used for the source material to ensure consistent quality and yield of active compounds.

Project actions

01When researching plant-based materials, investigate the cultivation and fertilization methods used.
02Consider how different agricultural practices might affect the chemical composition of your chosen materials.

Method & Evidence

AimHow do organic and organomineral fertilization strategies influence herbage yield, essential oil yield, and rosmarinic acid content in Melissa officinalis L. under field conditions?

MethodField Experiment

ProcedureA split-plot design was employed to evaluate the effects of six different fertilization treatments (including organic and organomineral combinations) on two cultivars of Melissa officinalis L. across two harvest times. Key metrics measured included fresh herbage yield, essential oil yield, and leaf rosmarinic acid content.

ContextAgricultural production of medicinal herbs

Variables

IVFertilization treatments (organic vs. organomineral), harvest times, cultivars

DVHerbage yield, essential oil yield, rosmarinic acid content

CVField conditions, plant cultivars (within main plots), harvest times (within subplots)

Strengths & Limitations

Strengths

+Field-based study provides realistic production data.
+Evaluation across multiple parameters (yield, EO, RA) offers a holistic view.

Limitations

The specific fertilizer combinations and their effects might vary depending on the plant species, soil type, and climate.

Reliability & validity

The use of a split-plot design and statistical analysis (p < 0.01) enhances the reliability of the findings. Validity is supported by multivariate analysis (PCA). However, generalizability may be limited by the specific environmental context.

Think critically

To what extent can these fertilization findings be generalized across different plant species and environmental conditions, and what are the potential trade-offs in terms of long-term soil health or environmental impact?

Design Principles

"Optimize resource inputs (nutrients) to maximize desired outputs (biomass and secondary metabolites) in plant-based product development."

This research highlights how strategic nutrient management can optimize the production of high-value compounds in crops, directly impacting the economic viability and resource efficiency of agricultural and botanical product design. Understanding these relationships allows for the development of more potent and cost-effective natural ingredients.

What This Means for Your Design

Using a mix of organic and mineral fertilizers can make plants like lemon balm produce more essential oils and a key compound called rosmarinic acid, which are valuable for health products.

Paragraph starter

The selection of plant-derived materials for design projects can be significantly influenced by their cultivation methods. Research indicates that organomineral fertilization strategies, as demonstrated in the study by Göre et al. (2026) on Melissa officinalis L., can substantially increase the yield of valuable secondary metabolites such as essential oils and rosmarinic acid by up to 99% compared to standard practices. This suggests that specifying or investigating the nutrient management of source materials can lead to more potent and cost-effective natural ingredients for product development.
