Introduction

The growth and production of green beans (Vigna Radiata L. Wilczek) are crucial factors in determining the success of agriculture. Various studies have been conducted to understand the response of green beans to different concentrations of herbicides, such as oryzalin. This study aims to investigate the growth response and production of two varieties of green beans, Vima-1 and Vima-2, to various concentrations of oryzalin.

Methodology

The study was conducted by Margaretta Sonia Sihombing at the Faculty of Agriculture, University of North Sumatra, from October 2019 to January 2020. The study was guided by Dr. Ir. Haryati, MP and Dr. Ir. Mariati Sinuraya, M.Sc. The method used was a random design group (rack) with two treatment factors: green bean varieties, namely Vima-1 and Vima-2, as well as oryzalin concentrations consisting of six levels, namely 0 μm (as control), 100 μm, 200 μm, 300 μm, 400 μm, and 500 μm.

Experimental Design

The experimental design consisted of a 2x6 factorial design, with two levels of green bean varieties (Vima-1 and Vima-2) and six levels of oryzalin concentrations (0 μm, 100 μm, 200 μm, 300 μm, 400 μm, and 500 μm). The green bean seeds were treated with oryzalin and those that were not treated were planted in polybags filled with a mixture of upper and compost soil with a ratio of 1:1.

Observed Variables

The observed variables included plant height, number of leaves, number of productive branches, flowering ages, number of pods per plant, seed weight per plant, and 100 seed weight. The results showed that varieties had a significant effect on the number of leaves at the age of 2 weeks after planting (WAP), where Vima-1 produced an average of 6.14 leaves, which was 92% more than Vima-2 which only produced 5.22 leaves.

Growth Response

However, when viewed from other growth parameters, such as plant height, number of leaves in 3, 4, and 5 WAP, as well as the number of productive branches, both varieties do not show significant differences. This shows that although VIMA-1 varieties show better growth at the beginning of growth, the difference does not continue to other growth parameters.

Interaction between Varieties and Oryzalin Concentration

The interaction between the treatment of varieties and the concentration of Oryzalin shows a significant effect on the weight of 100 seeds. Treatment of a combination of Vima-1 varieties without Oryzalin (V1K0) produces a weight of 100 seeds that are higher than other treatments. This indicates that the Vima-1 variety is more responsive to the condition without pressure from the Oryzalin, which can have positive implications for increasing production in the field.

Conclusion

This study provides an important insight into how green bean varieties can adapt to chemical treatment, such as oryzalin, and how these influences can vary depending on the variety used. By understanding this response, farmers and researchers can be more appropriate in choosing varieties and treatment that will be applied to increase the production of green beans. It is hoped that the results of this study can be a reference for the development of more sustainable and efficient green bean agriculture.

Implications

The results of this study have several implications for the development of green bean agriculture. Firstly, the study highlights the importance of choosing the right variety of green beans for a particular region or climate. Secondly, the study shows that the concentration of oryzalin can have a significant effect on the growth and production of green beans. Finally, the study suggests that the interaction between the treatment of varieties and the concentration of Oryzalin can have a significant effect on the weight of 100 seeds.

Future Research Directions

Future research directions include investigating the effects of other herbicides on the growth and production of green beans, as well as exploring the use of other treatment methods, such as organic farming practices. Additionally, further research is needed to understand the mechanisms underlying the interaction between the treatment of varieties and the concentration of Oryzalin.

Limitations

This study has several limitations. Firstly, the study was conducted in a controlled environment, which may not reflect the real-world conditions. Secondly, the study only investigated two varieties of green beans, which may not be representative of all green bean varieties. Finally, the study only used one type of herbicide, oryzalin, which may not be representative of all herbicides.

Recommendations

Based on the results of this study, the following recommendations can be made:

Choose the right variety of green beans for a particular region or climate.
Use the right concentration of oryzalin to avoid damaging the green beans.
Consider using other treatment methods, such as organic farming practices.
Further research is needed to understand the mechanisms underlying the interaction between the treatment of varieties and the concentration of Oryzalin.

Conclusion

In conclusion, this study provides an important insight into how green bean varieties can adapt to chemical treatment, such as oryzalin, and how these influences can vary depending on the variety used. By understanding this response, farmers and researchers can be more appropriate in choosing varieties and treatment that will be applied to increase the production of green beans. It is hoped that the results of this study can be a reference for the development of more sustainable and efficient green bean agriculture.

Q: What is oryzalin and how does it affect green beans?

A: Oryzalin is a herbicide that is commonly used to control weeds in agricultural fields. It works by inhibiting the growth of weeds, but it can also have an impact on the growth and production of green beans. In this study, we investigated the effects of different concentrations of oryzalin on the growth and production of two varieties of green beans.

Q: What are the effects of oryzalin on the growth of green beans?

A: Our study showed that oryzalin can have a significant impact on the growth of green beans. The concentration of oryzalin can affect the plant height, number of leaves, and number of productive branches of green beans. However, the effects of oryzalin on the growth of green beans can vary depending on the variety of green beans used.

Q: How does the concentration of oryzalin affect the production of green beans?

A: Our study showed that the concentration of oryzalin can have a significant impact on the production of green beans. The weight of 100 seeds was affected by the interaction between the treatment of varieties and the concentration of oryzalin. The treatment of a combination of Vima-1 varieties without oryzalin (V1K0) produced a weight of 100 seeds that was higher than other treatments.
