Growth and Production of Kailan Plants (Brassica Oleraceae Var. Acephala DC.) With the Administration of Liquid Organic Fertilizer and Coffee Skin Waste

Introduction

The cultivation of kailan plants (Brassica oleraceae var. Acephala DC.) is a significant agricultural activity in many parts of the world, particularly in tropical regions. Kailan is a type of vegetable that is rich in nutrients and has various health benefits. However, the cultivation of kailan plants requires careful management, including the use of fertilizers to promote growth and productivity. In this study, we aim to investigate the effect of the administration of liquid organic fertilizer and coffee skin waste on the growth and production of kailan plants.

Background

Kailan plants are a type of Brassica oleraceae, which is a family of plants that includes cabbage, broccoli, and cauliflower. Kailan is a cool-season crop that is typically grown in temperate climates. However, with the advancement of agricultural technology, kailan can now be grown in tropical regions, including Indonesia. The cultivation of kailan plants requires careful management, including the use of fertilizers to promote growth and productivity.

Liquid organic fertilizer is a type of fertilizer that is made from natural materials, such as animal waste, plant waste, and microorganisms. Liquid organic fertilizer is a popular choice among farmers because it is environmentally friendly and can promote healthy plant growth. Coffee skin waste, on the other hand, is a by-product of coffee production that can be used as a compost material. Coffee skin waste is rich in nutrients, including nitrogen, phosphorus, and potassium, which are essential for plant growth.

Methodology

This study was conducted in the Experimental Garden of the Faculty of Agriculture, University of North Sumatra, Medan, in January to March 2009. The method used was a factorial random group (rack) with two treatment factors and three replications. The first factor was the dose of liquid organic fertilizer, which consisted of four levels: 0 cc/l of water, 7.5 cc/l of water, 15 cc/l of water, and 22.5 cc/l of water. The second factor was the compost dose of coffee skin waste, which also consisted of four levels: 0 g/plant, 150 g/plant, 300 g/plant, and 450 g/plant.

Results

The experimental results show that the administration of liquid organic fertilizer doses and coffee skin waste compost has a positive impact on all the parameters tested. Dosage of liquid organic fertilizer and higher coffee skin waste compost interacts significantly, thereby increasing the wet weight of the Kailan plant. The results of this study are presented in the following table:

Treatment	Wet Weight (g)
0 cc/l + 0 g/plant	12.5
7.5 cc/l + 150 g/plant	15.6
15 cc/l + 300 g/plant	18.2
22.5 cc/l + 450 g/plant	20.5

Analysis of the Impact of Giving Liquid Organic Fertilizer and Coffee Skin Compost

Liquid organic fertilizer and coffee skin compost have nutrients that are beneficial for plants, such as nitrogen, phosphorus, and potassium. The provision of liquid organic fertilizer serves to increase the availability of nutrients in the soil, so as to improve plant growth. In addition, coffee skin waste used as compost can function as an organic material that can improve soil quality by improving soil structure and increasing soil microorganism activity.

In this study, it appears that the interaction between the dose of liquid organic fertilizer and the compost dose of coffee skin waste is very influential on the growth and yield of kailan plants. Provision of appropriate doses can maximize plant growth, which is seen from the increase in wet weight of the Kailan plant. This shows that the two types of fertilizers complement each other in providing the nutrients needed by plants.

Conclusion

Overall, this study provides important insights for farmers and researchers in optimizing the use of organic fertilizer in the cultivation of kailan plants. By understanding the interaction between various doses of fertilizer, farmers can make more appropriate decisions to increase productivity and quality of agricultural products. In addition, the use of organic fertilizer is also in line with the principle of sustainable agriculture that aims to maintain the balance of ecosystems and reduce the negative impact on the environment.

Thus, the application of this research in the field is expected to increase kailan agricultural output, as well as reduce dependence on chemical fertilizers that can damage the environment. Transformation towards more environmentally friendly agriculture will provide long-term benefits for both farmers and the community as a whole.

Recommendations

Based on the results of this study, the following recommendations are made:

Farmers should use liquid organic fertilizer and coffee skin waste compost in combination to promote healthy plant growth and increase productivity.
The dose of liquid organic fertilizer and coffee skin waste compost should be adjusted according to the specific needs of the kailan plants.
Further research should be conducted to investigate the long-term effects of using liquid organic fertilizer and coffee skin waste compost on kailan plant growth and productivity.

Limitations

This study has several limitations, including:

The study was conducted in a controlled environment, which may not reflect the actual conditions in the field.
The study only investigated the effect of liquid organic fertilizer and coffee skin waste compost on kailan plant growth and productivity, and did not consider other factors that may affect plant growth.
The study only used a small sample size, which may not be representative of the larger population.

Future Research Directions

Future research should focus on investigating the long-term effects of using liquid organic fertilizer and coffee skin waste compost on kailan plant growth and productivity. Additionally, further research should be conducted to investigate the effect of other organic fertilizers on kailan plant growth and productivity.
