The Potential of Various Plants as the Host of Arbuscular Mycorrhizal Inoculum and its Effect on the Growth of Corn and Soybean Plants in Simalingkar Ultisol

Introduction

Ultisol soil, commonly found in the Simalingkar region, is known to have low characteristics of nutrients, especially phosphorus (P). This is a challenge in increasing plant productivity, such as corn and soybeans. One potential solution is the use of arbuscular mycorrhiza (MA), mutualistic symbiosis between fungi and plant roots. Research conducted by Doli Saputra Hasibuan, under the guidance of T. Sabrina and Alida Lubis, aims to explore the potential of various types of plants as the host of the MA inoculum and test the impact on the growth of corn and soybean plants in Ultisol land.

Background

Ultisol soil is characterized by its low nutrient content, particularly phosphorus (P), which is essential for plant growth. This limitation can significantly impact the productivity of crops such as corn and soybeans. Arbuscular mycorrhizal (MA) fungi have been identified as a potential solution to this problem. MA is a mutualistic symbiosis between fungi and plant roots, where the fungi provide essential nutrients to the plant in exchange for carbohydrates.

Research Methodology

This study uses a random design group (rack) non-factorial, with different treatment based on the type of host plant for MA inoculum (corn, soybeans, peanuts, and Setaria grass). The results show that the administration of inoculum MA from various host plants significantly increases the growth of corn and soybean plants. Growth measured includes plant height, wet and dry weight of the canopy, root wet weight, and the degree of root infection.

Results

The significant increase in plant growth indicates the important role of MA in increasing the efficiency of the absorption of nutrients from the soil. The main mechanisms that play a role are:

  • Increased surface area of absorption: Hyphae expanding the reach of plant roots, so that it can absorb nutrients more effectively than areas that cannot be reached by plant roots.
  • Nutrition Mobilization: MA can dissolve and move nutrients bound in the soil, such as phosphorus, into a form that is more easily absorbed by plants.
  • Increased resistance to stress: MA can help plants survive abiotic stress, such as drought and salinity, and pathogenic attacks.

Although this study shows the positive effect of MA inoculum on plant growth, it should be noted that the N and P absorption of plants does not show a significant increase. This indicates that the MA mechanism in increasing nutritional absorption may be different for each type of nutrition.

Discussion

This research opens new opportunities in increasing plant productivity in ultisol soils. By utilizing the potential of MA of various types of host plants, we can increase the availability of nutrition and plant growth. The importance of this research lies in:

  • Identification of Effective Inoculum MA sources: This research identifies various host plants that can be used as an effective source of inoculum MA to increase corn and soybean growth.
  • Development of land management strategies: This research opens the way to develop a sustainable land management strategy, by utilizing the potential of the Supreme Court to increase crop productivity in Ultisol land.

Conclusion

By developing a better understanding of the Supreme Court, we can open new opportunities to increase plant productivity and build a more sustainable agricultural system. Further research is needed to:

  • Analyzing the MA mechanism in increasing nutritional absorption: To understand the underlying mechanisms of MA in increasing nutritional absorption.
  • Developing a more effective MA inoculation method: To improve the efficiency of MA inoculation and increase its effectiveness in increasing plant growth.
  • Study the effect of inoculum MA on various types of plants and soil conditions: To explore the potential of MA in different soil types and plant species.

Future Directions

This research has significant implications for the development of sustainable agricultural practices in ultisol soils. By utilizing the potential of MA, farmers can increase crop productivity and reduce the environmental impact of agriculture. Further research is needed to fully explore the potential of MA and develop effective strategies for its use in agriculture.
