The Growth of Orange Seedlings with the Treatment of Lower Metal Varieties and the Administration of Mycorrhizas in Andisol Soil

Introduction

The cultivation of orange trees is a significant industry in many parts of the world, with the fruit being a major source of income for farmers and a staple in many households. However, the quality of orange seeds can be affected by various factors, including the type of soil they are grown in and the presence of certain nutrients. In this study, we aimed to improve the quality of orange seeds by using lower stem varieties and administering arbuscular vesicular mycorrhiza (MVA) in Andisol soil, specifically in Karo Regency.

Background

Andisol soil is a type of soil that is rich in nutrients but has unique characteristics that can affect plant growth. The use of lower stem varieties and mycorrhizal inoculation has been shown to improve plant growth and increase the absorption of nutrients. However, the effectiveness of these methods in Andisol soil has not been extensively studied. In this experiment, we used a plot design with three replications, where each experimental unit consisted of four plants. The two main factors studied were the dose of mycorrhiza and the lower stem variety.

Materials and Methods

The dosage of mycorrhiza used consisted of four levels: without mycorrhizae (MO), 100 grams of mycorrhizae (M1), 200 grams of mycorrhizae (M2), and 300 grams of mycorrhizae (M3). As for the lower stem variety, three types were used: Japanhe Citroen (V1), Citromelo (V2), and Lime (V3). The response variables observed in this study included shoot height, number of leaves, total leaves, dry weight of buds, leaf area ratio, net assimilation rate, relative growth rate, degree of root infection, and absorption of phosphorus in the shoot tissue.

Results

The results showed that the lower stem varieties had a significant effect on the growth parameters of orange seeds. Japanehe Citroen (JC) varieties showed better growth compared to Citromelo and lime varieties. Mycorrhizal treatment also had a significant effect, where orange seeds invoculated with 300 grams of mycorrhizae showed optimal growth when compared to other treatments. There were also differences in responses from each lower stem variety to mycorrhizal inoculation in the absorption of phosphorus. The results showed that the JC varieties invoculated with 300 grams of mycorrhizae got the highest phosphorus absorption.

Discussion

Mycorrhiza is a symbiotic fungi that functions to expand plant root tissue, so that it can increase the ability of plants to absorb water and nutrients, especially phosphorus which is often an obstacle in plant growth. In this study, the improvement of the quality of orange seeds can be seen from an increase in various significant growth variables when mycorrhizae are applied. The selection of lower stem varieties is also very crucial. The right varieties will not only support plant growth, but also increase resistance to pests and diseases.

Conclusion

The application of mycorrhiza and the selection of appropriate lower rootstock varieties can be an effective strategy in orange cultivation, especially in the context of increasing the productivity and quality of plants in Andisol land which has unique characteristics. This is certainly beneficial for farmers and developers in an effort to improve sustainable agricultural output.

Recommendations

Based on the results of this study, we recommend the following:

  • The use of Japanehe Citroen (JC) varieties in orange cultivation, as they have shown superior growth parameters compared to other varieties.
  • The application of 300 grams of mycorrhizae per plant to improve the absorption of phosphorus and other nutrients.
  • Further research on local varieties and adaptation to specific soil conditions to improve the effectiveness of mycorrhizal inoculation.
  • The use of mycorrhizal inoculation in combination with other soil amendments to improve plant growth and increase the productivity of orange trees.

Future Directions

This study has provided valuable insights into the effectiveness of mycorrhizal inoculation and the selection of lower stem varieties in improving the quality of orange seeds. However, there are still many areas that require further research, including the effects of mycorrhizal inoculation on other nutrients and the long-term effects of mycorrhizal inoculation on plant growth. Additionally, the use of mycorrhizal inoculation in combination with other soil amendments and the effects of mycorrhizal inoculation on plant resistance to pests and diseases are areas that require further investigation.

Limitations

This study has several limitations, including the use of a small sample size and the lack of control over environmental factors. Additionally, the study was conducted in a controlled environment, and the results may not be generalizable to other environments. Further research is needed to confirm the findings of this study and to explore the effects of mycorrhizal inoculation in other environments.

Conclusion

In conclusion, this study has shown that the application of mycorrhiza and the selection of appropriate lower rootstock varieties can be an effective strategy in orange cultivation, especially in the context of increasing the productivity and quality of plants in Andisol land which has unique characteristics. The use of Japanehe Citroen (JC) varieties and the application of 300 grams of mycorrhizae per plant are recommended to improve the absorption of phosphorus and other nutrients. Further research is needed to confirm the findings of this study and to explore the effects of mycorrhizal inoculation in other environments.
