Abstract

Fenugreek (Trigonella foenum-graecum L.), a multipurpose spice and medicinal crop, thrives under organic management. Vermicompost, vermiwash, and moringa leaf extract are sustainable inputs that enhance soil fertility, nutrient uptake, and plant vigor. This review synthesizes studies from 2006 to 2022 to explore their synergistic effects on fenugreek’s growth (plant height, branches, dry matter) and yield (pods per plant, seeds per pod, seed yield) attributes. Vermicompost improves soil structure, vermiwash delivers foliar nutrients, and moringa leaf extract supplies growth-promoting compounds. These inputs collectively boost fenugreek productivity while reducing reliance on chemical fertilizers. The review also highlights economic benefits, emphasizing their role in sustainable agriculture. By integrating findings from field experiments, this study underscores the potential of these organic amendments for optimizing fenugreek cultivation.

Conclusion

Despite the proven benefits of vermicompost, vermiwash, and moringa leaf extract in enhancing fenugreek growth and yield, several challenges must be addressed for their widespread adoption. One major concern is the inconsistent quality and availability of organic inputs, especially in rural or resource-limited areas. Variability in nutrient content, microbial activity, and preparation methods can lead to uneven field performance. Additionally, the lack of standardized application protocols regarding dosage, frequency, and mode of application (soil vs. foliar) may limit the reproducibility of positive results across different agro-ecological zones. Moreover, transitioning from conventional to organic systems requires a shift in farmer mindset, initial investment, and training. There is limited awareness about the synergistic effects of these inputs, and many farmers still rely heavily on chemical fertilizers due to their quick results. Also, the short shelf-life of liquid formulations like vermiwash and moringa leaf extract can affect their efficacy if not stored or applied properly. To overcome these issues, there is a need for robust extension services, quality certification systems, and localized research to develop user-friendly, cost-effective organic input packages tailored to fenugreek cultivation
