The Growth And Production Response Of Lettuce Plants (Lactuca Sativa L.) To The Planting Media And The Provision Of Liquid Organic Fertilizer
Introduction
Lettuce (Lactuca sativa L.) is one of the most widely cultivated leafy green vegetables globally, with a high demand for its nutritional value and versatility in various cuisines. However, the cultivation of lettuce often faces challenges related to soil quality, nutrient availability, and environmental sustainability. This study aims to investigate the effect of planting media and liquid organic fertilizer on the growth and production of lettuce, with a focus on utilizing oil palm solid waste as an alternative planting medium.
Methodology
This study employed a factorial random group design (shelf) with two main factors:
First Factor: Planting Media
The planting media used in this study consisted of different compositions of soil and oil palm solid waste, specifically:
- 100% soil + 0% waste
- 75% soil + 25% waste
- 50% soil + 50% waste
- 25% soil + 75% waste
Second Factor: Provision of Liquid Organic Fertilizer
The liquid organic fertilizer was applied at different doses, specifically:
- 0 cc/liter of water
- 2 cc/liter of water
- 4 cc/liter of water
- 6 cc/liter of water
Measurement Parameters
This research observed several important parameters, including:
- Plant height (cm)
- Number of leaves (strands)
- Leaf area (cm²)
- Root volume (ml)
- Plant length (cm)
- Consumption of decent wet weight (g)
- Leaf chlorophyll (unit/6mm³)
- Dry weight of plants (g)
- Clean assimilation rate (gm ֿ ֿ ² h)
- Relative growth rate (gm ֿ ֿ ¹¹h)
Research Results
The results showed that the planting media had a significant effect on all observed parameters, including plant height, number of leaves, total leaf area, root volume, plant length, decent wet weight consumption, leaf chlorophyll, plant dry weight, net assimilation rate, and relative growth rate.
Conversely, the administration of liquid organic fertilizer did not show a significant effect on the growth and production of lettuce. Likewise, the interaction between planting media and liquid organic fertilizer did not have a significant effect on the observed parameters.
The Best Treatment Combination
The best combination of treatment was M3P2, which consisted of 25% soil planting media + 75% of palm solid waste with 4 cc/liter of liquid organic fertilizer. This combination showed the optimal results of growth and lettuce production.
Deeper Analysis
The results of this study indicate that the use of palm oil solid waste as a planting medium has the potential to increase the growth and production of lettuce. Palm solid waste contains important nutrients for plants, such as nitrogen, phosphorus, and potassium, which play an important role in vegetative and generative growth of plants.
Although liquid organic fertilizer did not show a significant effect on this study, the use of organic fertilizer can provide long-term benefits by increasing soil fertility and increasing plant resistance to pest and disease attacks.
Recommendations and Conclusions
This study highlights the importance of the selection of appropriate planting media to optimize the growth and production of lettuce. The use of oil palm solid waste as a planting medium, especially with a combination of 25% soil and 75% waste, promises better results compared to the use of pure land.
Further research needs to be done to examine the optimal dose of liquid organic fertilizer and the interaction between liquid organic fertilizer and different planting media.
Thus, this research makes an important contribution to the development of more efficient and sustainable lettuce cultivation, especially by utilizing oil palm waste as an alternative planting medium.
Implications and Future Directions
The findings of this study have significant implications for the development of sustainable and efficient lettuce cultivation practices. The use of oil palm solid waste as a planting medium can reduce waste disposal costs and provide a valuable source of nutrients for plants.
Future research should focus on optimizing the dose of liquid organic fertilizer and exploring the interaction between liquid organic fertilizer and different planting media. Additionally, the study of the long-term effects of using oil palm solid waste as a planting medium on soil fertility and plant health is essential.
Conclusion
In conclusion, this study demonstrates the potential of using oil palm solid waste as a planting medium for lettuce cultivation. The results show that the use of palm oil solid waste can increase the growth and production of lettuce, while the administration of liquid organic fertilizer does not have a significant effect.
The findings of this study contribute to the development of more efficient and sustainable lettuce cultivation practices, reducing waste disposal costs and providing a valuable source of nutrients for plants. Further research is needed to optimize the use of oil palm solid waste as a planting medium and to explore the long-term effects of its use on soil fertility and plant health.
