The Growth and Results of Several Soybean Varieties Under 4 Years of Palm Oil Stands and 8 Years: A Study on Sustainable Agriculture

Introduction

Soybeans are one of the most widely cultivated legumes in the world, known for their high protein content and versatility in food and industrial applications. As a crop, soybeans require adequate light, water, and nutrients to grow and thrive. However, the presence of oil palm stands can significantly impact the growth and results of soybean varieties. This study aims to investigate the growth and results of various soybean varieties planted under 4 years old and 8 years old oil palm stands, with a focus on sustainable agriculture practices.

Background

Soybeans are annual plants that are rich in protein and have an important role in the food industry. The demand for soybeans is increasing globally, driven by the growing demand for plant-based protein sources. However, soybean production is often limited by factors such as land availability, climate, and soil quality. In Indonesia, where this study was conducted, oil palm stands are a common land use practice, covering millions of hectares of land. The presence of oil palm stands can impact the growth and results of soybean varieties, making it essential to investigate the effects of oil palm age on soybean growth and results.

Methodology

This study was conducted with a split plot factor experimental design involving 3 replications, with the main plot that included oil palm age (TM1: 4 years, TM2: 8 years) and subplots that include soybean varieties (V1: Grobogan, V2: Anjasmoro, V3: Dena 1, V4: Wilis). The research location is in Kota Datar Village, Hamparan Perak District, Deli Serdang Regency, North Sumatra. The study involved measuring various growth parameters, including plant height, number of productive branches, total leaf area, and 100 seed dry weight.

Results

The results of this study showed that the treatment of oil palm age did not have a significant effect on all growth parameters. However, the diversity of soybean varieties shows a real impact. At the age of five weeks after planting, Grobogan varieties have the highest plant height, which is 39.53 cm, and the number of productive branches is 9.25 branches. The interaction between the age of oil palm and soybean varieties also shows significant results in several parameters. In Grobogan soybean plants planted under 4 years old oil palm stands, total leaf area reaches 1167.67 cm². Meanwhile, for Grobogan soybeans planted under 8 years old oil palm, 100 seed dry weight reached 19.27 grams.

Discussion

The results of this study indicate that soybean varieties have different responses to environmental factors produced by oil palm stands. The existence of oil palm as a shade can affect the intensity of the light received by soybean plants, which subsequently impacts the growth and results. The lighting factor is very crucial in plant growth, especially for soybeans that require enough light for photosynthesis. Grobogan varieties that show the best performance in this study can be an indication that these varieties are more adaptive to light conditions that may be more dim due to oil palm stands.

Conclusion

In conclusion, this research opens new opportunities for farmers and entrepreneurs to maximize land use, as well as optimize agricultural products through the selection of appropriate varieties in accordance with environmental conditions. The use of vacant land around oil palm for planting soybeans can be a promising alternative, increasing land productivity and contributing to diversification of farm businesses and improving sustainable agricultural patterns.

Recommendations

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

  1. Further research is needed to explore the potential of other soybean varieties and a combination of aquaculture techniques that can increase soybean agricultural output in land that is managed together with oil palm.
  2. The use of vacant land around oil palm for planting soybeans can be a promising alternative, increasing land productivity and contributing to diversification of farm businesses and improving sustainable agricultural patterns.
  3. The selection of appropriate soybean varieties in accordance with environmental conditions can optimize agricultural products and maximize land use.

Limitations

This study has several limitations, including:

  1. The study was conducted in a single location, and the results may not be generalizable to other locations.
  2. The study only investigated the effects of oil palm age on soybean growth and results, and did not consider other factors that may impact soybean production.
  3. The study only used a limited number of soybean varieties, and further research is needed to explore the potential of other varieties.

Future Research Directions

Future research directions include:

  1. Investigating the effects of other factors, such as climate, soil quality, and irrigation, on soybean growth and results.
  2. Exploring the potential of other soybean varieties and a combination of aquaculture techniques that can increase soybean agricultural output in land that is managed together with oil palm.
  3. Developing sustainable agricultural practices that can optimize land use and improve agricultural productivity.
