The Effect Of The Rootstock Wrap And Phosphate Fertilizer against The Growth Of The Sleeping Eye Stum Rubber (Hevea Brasiliensis Muell Arg.)

The Effect of Rootstock Wrap and Phosphate Fertilizer Against the Growth of Sleeping Eye Stum Rubber (Hevea Brasiliensis Muell Arg.)

Introduction

Rubber (Hevea brasiliensis Muell Arg.) is one of the most important industrial crops in the world, with a significant economic potential. The growth of rubber plants is influenced by various factors, including environmental conditions and fertilization techniques. This study aims to investigate the effect of rootstock wrap and phosphate fertilizer on the growth of sleeping eye stum rubber (Hevea brasiliensis Muell Arg.). The study was conducted on the experimental land of the Faculty of Agriculture, University of North Sumatra, Medan, at an altitude of about 25 meters above sea level, from June to October 2009.

Methodology

This study used a random design group with two factors. The level of the rootstock wrap (L) is the main factor with three levels, namely 3.6 - 4.6 cm (L1), 4.7 - 5.7 cm (L2), and 5.8 - 6.8 cm (L3). Phosphate fertilizer as the second factor with four levels, namely 0 g (F1), 15 g (F2), 30 g (F3), and 45 g (F4), with three replications. The parameters observed in this study include the speed of growth of sleeping eye stum, the percentage of buds growth, bud length, shoot wrap, number of leaves, and the percentage of umbrella leaves on the stum.

Results

The results showed that the lower stem wrapped at the L3 level gave the best results on the length of the shoots, the number of shoots, and the number of leaves. Nevertheless, the rootstock wrap does not have a significant effect on the time of buds growth, the percentage of buds growth, and the percentage of umbrella leaves. In terms of phosphate fertilizer treatment, F3 treatment (30 g) shows the best results in increasing the length of the shoots. The interaction between these two factors has a significant effect on the length of the bud. The combination of the treatment that produces the highest bud length is L3F1 (bottom barrier 5.8-6.8 cm and phosphate fertilizer 15 g), which is proven to be significant in increasing the growth of rubber stum.

Discussion

The provision of phosphate fertilizer plays an important role in supporting the growth of rubber plants. Phosphate is an essential nutrient that supports the process of photosynthesis, as well as plays a role in the formation of roots and shoot growth. In this study, the optimal combination of stem wraps and the appropriate dose of phosphate fertilizer provides a significant encouragement to the growth of STUM. The stem wrap factor is directly related to the health and ability of plants to get nutrition from the soil. Plants with larger stem wrap generally have a better root system, so that it can absorb more water and nutrients.

Conclusion

The results of this study are a reference for rubber farmers in caring for and maintaining their plants. By knowing the right combination of stem wraps and phosphate fertilizer treatment, farmers can significantly increase their rubber plant productivity. In addition, this research also contributes to the development of sustainable agricultural techniques, where the use of fertilizer can be optimized to produce maximum results without damaging the environment. Overall, this study confirms the importance of attention to environmental factors and fertilization techniques in the growth of rubber plants, as well as how the right combination can affect the final outcome.

Recommendations

It is hoped that this research can trigger further studies that can enrich knowledge about the agronomy of rubber plants and increase the competitiveness of Indonesian rubber products in the global market. The findings of this study can be applied in the field to improve the productivity of rubber plants and to develop sustainable agricultural techniques.

Limitations

This study has some limitations, including the small sample size and the limited number of factors studied. Further research is needed to confirm the findings of this study and to explore the effects of other factors on the growth of rubber plants.

Future Research Directions

Future research should focus on exploring the effects of other factors on the growth of rubber plants, such as climate change, soil quality, and pest management. Additionally, research should be conducted to develop more efficient and sustainable fertilization techniques for rubber plants.
