Response of Several Soybean Varieties (Glycine Max L. Merril.) In the State of Stagnant to the Administration of BAP and GA3

Climate Change and Soybean Productivity

Climate change in Indonesia has led to an increase in the risk of inundation in soybean planting areas during high rainfall. This can significantly impact soybean productivity, which is one of the most important food crops in the country. Soybeans are very sensitive plants, and the presence of puddles can be a major problem in many agricultural areas around the world. To overcome this, the use of growth regulators such as BAP (Benzyl Amino Purine) and GA3 (Gibbellin Acid) can stimulate the adaptive reactions of soybean plants in the face of inundation stress.

Research Methodology

Research was conducted on the experimental land of the Faculty of Agriculture, University of North Sumatra, Medan, Indonesia, at an altitude of about 32 meters above sea level from March to August 2018. The design used was a random design group (rack) with three treatment factors: varieties (Willis, Ring 1, and Devon 1), the concentration of growth regulators (control, GA3 100 ppm + BAP 30 ppm, and GA3 200 ppm + BAP 60 ppm), and inundation (control and inundated).

Parameters Measured

The parameters measured in this study included:

Plant height
Number of leaves
Flowering age
Number of pods containing per plant
Number of seeds per plant
Weight of 100 seeds
Chlorophyll analysis
Protein analysis
Analysis of the superoxide dismutase (SOD) enzyme

Results and Discussion

The results showed that soybean varieties had a significant effect on plant height two weeks after planting (MST), 100 seed weight, and flowering age. The inundation treatment also had a significant impact on the total chlorophyll of soybean plants.

In addition, the interaction between varieties and growth regulators has a significant effect on the number of seeds and weights of 100 seeds. This shows that some soybean varieties are more responsive to the treatment of growth regulators in inundation conditions. The interaction between inundation and growth regulators also has a significant effect on the age of flowering soybean plants, which indicate that the application of growth regulators can help accelerate or slow down the flowering phase in stagnant conditions.

Understanding the Impact of Inundation on Soybean Growth

Understanding the impact of inundation on soybean growth is very important, especially in the midst of increasingly urgent climate change issues. With the more frequent inundation due to high rainfall, farmers need to have a choice of soybean varieties that are more resistant to these conditions. In this study, varieties such as Willis, Ring 1, and Devon 1 were tested to assess the level of durability.

The Use of Growth Regulators

The use of growth regulators such as GA3 and BAP can be an effective mitigation strategy. GA3, which is known to stimulate cell growth, can help plants survive better in stagnant conditions. Meanwhile, BAP can encourage shoot growth, so it is expected to increase plant productivity even in less ideal conditions.

Conclusion and Recommendations

From the results of the study, we can draw the conclusion that appropriate varieties and optimal application of growth regulators can increase soybean adaptation to inundation. Further research needs to be done to explore varieties and concentrations of growth regulators that are most effective in various environmental conditions. This will not only be beneficial for soybean farmers, but also contribute to increasing national food security in the midst of increasingly real climate change challenges.

Future Research Directions

Through this research, it is expected that there will be an increase in more sustainable and adaptive soybean agriculture practices to climate change, and ensure better productivity in the future. Further research is needed to explore the following:

The effect of different concentrations of GA3 and BAP on soybean growth and productivity
The interaction between soybean varieties and growth regulators in different environmental conditions
The development of new soybean varieties that are more resistant to inundation

Implications for Soybean Farmers and National Food Security

The results of this study have significant implications for soybean farmers and national food security. The use of growth regulators such as GA3 and BAP can help increase soybean adaptation to inundation, which can lead to increased productivity and better food security. Further research is needed to explore the potential of these growth regulators in different environmental conditions.

Limitations and Future Research Directions

This study has several limitations, including the use of a small number of soybean varieties and the limited range of environmental conditions tested. Further research is needed to explore the effect of different concentrations of GA3 and BAP on soybean growth and productivity, as well as the interaction between soybean varieties and growth regulators in different environmental conditions.

Conclusion

In conclusion, this study has shown that the use of growth regulators such as GA3 and BAP can increase soybean adaptation to inundation. Further research is needed to explore the potential of these growth regulators in different environmental conditions, as well as the development of new soybean varieties that are more resistant to inundation.
