Growth and Production of Beans (Phaseolus vulgaris L.) in Various Concentrations of Gibberellins and Long Soaking of Seeds

Introduction

Beans (Phaseolus vulgaris L.) are one of the most widely cultivated legumes in the world, providing a rich source of protein, fiber, and essential nutrients for human consumption. The growth and production of beans are influenced by various factors, including environmental conditions, soil quality, and plant growth regulators. Gibberellins, a class of plant growth regulators, play a crucial role in stimulating plant growth and development, particularly in the vegetative phase. This study aims to explore the effect of growth and production of beans in various concentrations of gibberellins and the duration of seed soaking.

Materials and Methods

The study was conducted in Hutaraja Village, Doloksanggul District, Humbang Hasudutan Regency, North Sumatra, at an altitude of about 1500 meters above sea level. The research took place from June to September 2020. A random design group (shelf) was used, including two factors and repeated three times. The first factor included gibberellin concentration, namely 0 ppm, 10 ppm, 20 ppm, and 30 ppm. The second factor was the length of seed soaking, which was 1 hour, 2 hours, and 3 hours. Various observed parameters included the length of the plant, the number of leaves, the leaf area, the number of primary branches, the age of flowering, the number of flowers, the number of fruits, the length of the pods, and the weight of the fruit.

Results

The results showed that the concentration of gibberellins had a significant effect on the number of interest, but not on other parameters. Conversely, the length of seed immersion had a significant effect on the number of leaves in the second and third weeks after planting (MST). Interestingly, no significant interaction was found between the concentration of gibberellins and the length of seed soaking.

Discussion

The use of gibberellins as plant growth regulators can trigger physiological processes in beans. Gibberellins play a role in stimulating plant growth and development, especially in the vegetative phase. The findings that gibberellin concentrations have a significant effect on the number of interest show that the use of gibberellins needs to be done carefully to get optimal results.

Meanwhile, the duration of seed soaking has a broader impact on leaf growth. Soaking of seeds for 2 hours and 3 hours is proven to increase the number of leaves, which are important indicators in the process of photosynthesis and energy production for plant growth. This shows that seed immersion can increase the vitality and growth of seeds, which contribute to crop production.

It is essential to note that in the process of breeding and cultivation of beans, gibberellin arrangements and seed immersion techniques must be calculated precisely. Farmers and researchers need to understand that although gibberellins can help in increasing the amount of flowers, other aspects of plant growth must also be considered so that there is no decrease in results due to other factors such as leaf deficiency for photosynthesis.

Conclusion

This study provides valuable insights on bean cultivation techniques that can help increase plant productivity through regulation of gibberellin concentration and seedling of seed immersion time. By implementing this knowledge, it is expected that farmers can increase agricultural products on a sustainable manner.

Recommendations

Based on the findings of this study, the following recommendations are made:

Optimize gibberellin concentration: Farmers and researchers should carefully consider the optimal concentration of gibberellins to be used in bean cultivation to avoid any negative effects on plant growth.
Adjust seed soaking time: The duration of seed soaking should be adjusted according to the specific needs of the crop to maximize leaf growth and plant productivity.
Monitor plant growth: Regular monitoring of plant growth and development is essential to ensure that the use of gibberellins and seed soaking techniques is effective and does not lead to any negative consequences.
Develop sustainable cultivation practices: Farmers and researchers should work together to develop sustainable cultivation practices that take into account the specific needs of the crop and the environment.

Future Research Directions

This study provides a foundation for further research on the effects of gibberellins and seed soaking on bean cultivation. Future studies should focus on:

Investigating the effects of gibberellins on other plant growth parameters: Further research is needed to investigate the effects of gibberellins on other plant growth parameters, such as root growth, stem elongation, and flower formation.
Exploring the interaction between gibberellins and other plant growth regulators: The interaction between gibberellins and other plant growth regulators, such as auxins and cytokinins, should be explored to understand their combined effects on plant growth and development.
Developing new seed soaking techniques: New seed soaking techniques should be developed to optimize leaf growth and plant productivity in bean cultivation.

Limitations of the Study

This study has several limitations that should be considered when interpreting the results:

Limited sample size: The sample size of this study was limited, which may have affected the accuracy of the results.
Single location: The study was conducted at a single location, which may not be representative of other regions or environments.
Limited duration: The study was conducted over a limited duration, which may not have captured the full effects of gibberellins and seed soaking on plant growth and development.

Conclusion

In conclusion, this study provides valuable insights on the effects of gibberellins and seed soaking on bean cultivation. The findings of this study highlight the importance of optimizing gibberellin concentration and seed soaking time to maximize plant productivity. Future research should focus on exploring the interaction between gibberellins and other plant growth regulators, developing new seed soaking techniques, and investigating the effects of gibberellins on other plant growth parameters.
