Potential of Tofu Liquid Waste as Liquid Organic Fertilizer for Kailan Mustard Plants

Introduction

Tofu liquid waste, often regarded as garbage, has been found to store great potential as liquid organic fertilizer for plants, particularly Sawi Kailan (Brassica Oleracea var. Alboglabra (L. H. Bailey) Musil). A study conducted at the Plant Physiology Laboratory and Plant Tissue Culture, Faculty of Mathematics and Natural Sciences, University of North Sumatra, from May to August 2019, aimed to explore the effect of tofu waste incubation time with the effective microorganism (EM) on plant morphysiological responses Kailan.

Background and Significance

The increasing awareness of the importance of sustainable agriculture and the use of organic fertilizer has led to a growing interest in exploring alternative sources of fertilizer. Tofu liquid waste, which is often discarded, contains a significant amount of nutrients that can be absorbed by plants, such as nitrogen, phosphorus, and potassium. The use of tofu liquid waste as liquid organic fertilizer not only provides a sustainable solution for waste management but also offers a cost-effective alternative to synthetic fertilizers.

Methodology

This study used a Complete Randomized Design (RAL) with four variations in the incubation time of tofu liquid waste with EM, namely 24, 36, 48, and 60 hours. The results showed that the incubation of tofu liquid waste with EM had a significant impact on the height of the Kailan plant from the first week to the fourth week after treatment. In addition, there was a significant increase in the relative growth rate (RGR) in the second, third, and sixth week after treatment, as well as an increase in the number of leaves, canopy biomass, root/canopy ratio, and chlorophyll content b. However, this positive effect began to decline in the fifth to seventh week, where no significant effect was found on some growth parameters such as plant height, RGR, leaf area, root biomass, and chlorophyll content a.

Results and Discussion

The results of the study showed that the incubation time of tofu liquid waste with EM for 36 hours and 60 hours was the most effective time to increase the growth of Kailan plants. This suggests that the fermentation process with EM can convert tofu liquid waste into a source of nutrition that is beneficial for plants. The process of incubation of tofu liquid waste with EM also facilitates the formation of active compounds that encourage plant growth.

Additional Analysis and Explanation

The utilization of tofu liquid waste as liquid organic fertilizer not only has the potential to increase plant growth but also provides sustainable solutions for waste management. The discovery that 36 hours of incubation time and 60 hours gave the best results highlights the importance of regulating time in the fermentation process. Therefore, for farmers who want to adopt this method, it is recommended to pay attention to incubation time in order to maximize the results of the growth of their plants.

Conclusion

This study provides valuable insights for agricultural practitioners on the potential of tofu liquid waste as liquid organic fertilizer for Kailan mustard plants. The results of the study suggest that the fermentation process with EM can convert tofu liquid waste into a source of nutrition that is beneficial for plants. The utilization of tofu liquid waste as liquid organic fertilizer not only provides a sustainable solution for waste management but also offers a cost-effective alternative to synthetic fertilizers.

Recommendations

Based on the results of the study, it is recommended that farmers pay attention to incubation time in order to maximize the results of the growth of their plants. The study also suggests that further research is needed to explore the potential of tofu liquid waste as liquid organic fertilizer for other crops.

Future Directions

The development and application of tofu liquid waste management technology into liquid organic fertilizer is a positive step towards a more sustainable agriculture. Further research is needed to explore the potential of tofu liquid waste as liquid organic fertilizer for other crops and to develop more efficient methods for its production and application.

Limitations and Future Research Directions

This study has several limitations, including the small sample size and the limited number of variables tested. Further research is needed to explore the potential of tofu liquid waste as liquid organic fertilizer for other crops and to develop more efficient methods for its production and application.

Conclusion

In conclusion, this study provides valuable insights for agricultural practitioners on the potential of tofu liquid waste as liquid organic fertilizer for Kailan mustard plants. The results of the study suggest that the fermentation process with EM can convert tofu liquid waste into a source of nutrition that is beneficial for plants. The utilization of tofu liquid waste as liquid organic fertilizer not only provides a sustainable solution for waste management but also offers a cost-effective alternative to synthetic fertilizers.
