Growth of Kenaf (Hibiscus cannabinus L.) with differences in spacing and cutting of shoots

Kenaf (Hibiscus cannabinus L.) is a fiber plant that has gained significant attention in recent years due to its high economic potential. As a short day fiber plant, Kenaf is an alternative source of fiber that can be used to produce various industry products, including burlap sacks and other prospective products. However, the development of natural fibers in Indonesia faces various challenges, including technical and non-technical issues that affect the productivity and quality of results at the farm level.

Challenges in Kenaf Development

The development of Kenaf faces several technical challenges, including the selection of superior varieties, less efficient cultivation techniques, and the lack of quality seed supply. To overcome these challenges, technological innovation is crucial, ranging from the assembly of superior varieties, the development of better cultivation methods, to the provision of quality seed sources. Additionally, non-technical challenges such as lack of knowledge and skills among farmers, limited access to resources and markets, and inadequate policies and regulations also hinder the development of Kenaf.

Research Objectives

This study aims to investigate the growth of Kenaf based on differences in spacing and shooting methods. The study was conducted at the Tanjung Anom Seed Center, Medan, from August to October 2015, using a random factorial group design involving two factors. The first factor is the spacing of crops consisting of 20 cm x 20 cm, 40 cm x 20 cm, 60 cm x 20 cm, and 80 cm x 20 cm. The second factor is pruning treatment, which includes pruning and without pruning.

Research Methodology

The study used a random factorial group design, which involves two factors: spacing and pruning treatment. The spacing factor consisted of four levels: 20 cm x 20 cm, 40 cm x 20 cm, 60 cm x 20 cm, and 80 cm x 20 cm. The pruning treatment factor consisted of two levels: pruning and without pruning. The study was conducted at the Tanjung Anom Seed Center, Medan, and the data was collected from August to October 2015.

Research Results

The results of the study showed that the treatment with wider planting distance (J2) was able to increase plant height, plant diameter, and fresh root weight. Meanwhile, pruning treatment (P2) also has a positive impact by increasing plant height and fresh root weight. In addition, the interaction between spacing and pruning has been proven to have a significant effect in increasing the diameter of plants.

Analysis and Explanation

The increased growth of Kenaf observed in this study can be explained by several factors. Wider planting distance provides more space for plants to develop, thus supporting better root growth and more optimal absorption of nutrients. On the other hand, the cutting of shoots serves to stimulate more branches, which in turn can increase the number of leaves. The number of leaves that contribute more to increased photosynthesis, which results in better plant growth.

Optimizing the spacing and pruning of shoots not only affects the physical growth of plants, but also has the potential to increase the yield of the fiber produced. With a better understanding of the interaction between spacing and pruning, farmers can apply more efficient cultivation techniques to increase the productivity of Kenaf.

Conclusion

This study provides an important insight into the growth of Kenaf by paying attention to the spacing and pruning of the shoots. By adopting proper aquaculture practices, it is expected that Kenaf productivity can increase, provide greater economic benefits for farmers, and contribute to the development of the fiber industry in Indonesia. The use of the right method in managing Kenaf plants can be the first step to achieve success in the cultivation of this fiber plant.

Recommendations

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

Farmers should adopt wider planting distance (J2) to increase plant height, plant diameter, and fresh root weight.
Pruning treatment (P2) should be applied to increase plant height and fresh root weight.
The interaction between spacing and pruning should be taken into account to increase the diameter of plants.
Further research should be conducted to investigate the effects of other factors on the growth of Kenaf.

Limitations of the Study

This study has several limitations, including:

The study was conducted at a single location, which may not be representative of other locations.
The study only investigated the effects of spacing and pruning treatment on the growth of Kenaf.
The study did not investigate the effects of other factors on the growth of Kenaf.

Future Research Directions

Future research should be conducted to investigate the effects of other factors on the growth of Kenaf, including:

The effects of different varieties of Kenaf on growth and productivity.
The effects of different cultivation methods on growth and productivity.
The effects of different pruning treatments on growth and productivity.

By conducting further research, it is expected that a better understanding of the growth of Kenaf can be achieved, which can lead to the development of more efficient cultivation techniques and increased productivity of Kenaf.
