Growth in Kenaf (Hibiscus cannabicus L.) with differences in spacing and fertilizer n, P, and K

Introduction

In recent years, the demand for sustainable and eco-friendly crops has been on the rise. One such crop that has gained significant attention is Kenaf (Hibiscus cannabicus L.), a versatile and highly productive plant that can be used for various purposes, including paper production, animal feed, and biofuel. However, to increase the productivity of Kenaf and optimize land use, it is essential to regulate the spacing and provide adequate nutrition through fertilization. This study aims to investigate the effects of different spacing and fertilizer treatments on the growth of Kenaf.

Methodology

The study was conducted in Block 6 Afdeling II Kebun Adolina, Deli Serdang Regency, North Sumatra, from October to December 2016. The research design used a random design of factorial groups, which included two main factors: spacing (20x20 cm, 40x20 cm, and 60x20 cm) and the dosage of N, P, and K fertilizer with a variety of specified comparisons.

In this study, fertilizer treatment was given in the form of:

  • Treatment 0 g (control): 2,40 g urea; 0.60 g TSP; 0.60 g KCl per planting hole.
  • Medium treatment: 3,60 g urea; 1.20 g TSP; 1.20 g KCl per planting hole.
  • High treatment: 4,80 g urea; 2,40 g TSP; 2,40 g KCl per planting hole.

Results

The results showed that the spacing of 60x20 cm (J3) significantly increased the number of leaves, stem diameter, fresh weight of the canopy, and the dry weight of the canopy. In addition, fertilization with the ratio of N, P, and K 4.8: 2,4: 2,4 (P3) also increases all of these growth parameters significantly. Meanwhile, the highest plant height is produced in a spacing treatment of 20x20 cm (J1) with fertilization N, P, and K in a ratio of 2.4: 0.6: 0.6 (P1), which shows results that are not too different than the treatment other.

Discussion

The optimal growth of Kenaf is strongly influenced by the spacing and nutrients given. By using a spacing of 60x20 cm, Kenaf plants have a wider space to develop, which allows better access to sunlight and better air flow. This contributes to the reduction of competition between plants, so that the growth of each individual becomes more leverage.

In addition, the right fertilization also plays an important role. N, P, and K fertilizer functions to support various physiological processes in plants. Nitrogen (N) is very instrumental in vegetative growth, phosphorus (P) is important for root development, and potassium (K) supports plant resistance to stress. Therefore, a balanced dose of fertilizer as in the treatment 4.8: 2.4: 2.4 (P3) is very effective in supporting optimal growth.

Recommendations

Recommendations from this study indicate that to achieve the best growth of Kenaf, you should use a 60x20 cm planting distance along with N, P, and K fertilization in a ratio of 4.8: 2.4: 2.4. This not only increases yields, but also provides long-term benefits for the sustainability of the cultivation of Kenff in the future.

Conclusion

In conclusion, this research provides valuable insights on ways to increase the productivity of Kenaf through the regulation of planting distances and the use of appropriate fertilizer. By applying the recommended method, farmers can maximize the results and efficiency of the land used.

Future Directions

Future studies can focus on investigating the effects of different fertilizer treatments on the growth of Kenaf, as well as exploring the potential of using Kenaf as a biofuel crop. Additionally, research can be conducted on the economic feasibility of large-scale Kenaf cultivation and the potential for Kenaf to be used as a sustainable crop in various regions.

Limitations

This study has several limitations, including the small sample size and the limited number of fertilizer treatments used. Future studies can build on this research by increasing the sample size and exploring a wider range of fertilizer treatments.
