Response Of Three Soybean Varieties To The Administration Of Rhizobium In Gawangan Rubber Tbm 1
Introduction
The use of rhizobium in soybean cultivation has been a topic of interest in recent years, as it has the potential to increase nitrogen availability in the soil and support plant growth. This study aims to reveal the effect of three soybean varieties on the growth and production in the Gawangan TBM Rubber Plant 1, with a focus on the role of rhizobium in this process. The study was conducted in the experimental area of the Agricultural Technology Assessment Center (BPTP) Sungai Putih, North Sumatra, with a height of ± 80 meters above sea level.
Methodology
The study took place from August to November 2014 using a random design group (RAK) with two factors and three replications. The first factor is soybean varieties, namely IPB 1, Wilis, and Anjasmoro. The second factor is the use of rhizobium with a density of 10^9 g/ml per plant and without rhizobium. The results showed that differences in varieties had a significant effect on plant height at the age of 2-5 weeks, the number of leaves at the age of 3 weeks, total leaf area, and weight of 100 seeds per plot. However, differences in varieties with the application of Rhizobium and the interaction of the two do not show a significant effect on all observed parameters.
Why are the differences in varieties influential?
The significant difference in growth and production between the three soybean varieties can be caused by several factors, such as:
Genotype
Each variety has different genetic characteristics, including the ability to absorb nutrients, tolerance to environmental conditions, and potential crops. The genetic makeup of each variety can affect its ability to grow and produce in different environments.
Adaptation
More adaptive varieties of soil and climate conditions in TBM 1 rubber gawangan will grow and produce better. The ability of a variety to adapt to its environment can greatly affect its growth and production.
Nitrogen fixation ability
The ability of varieties in utilizing nitrogen from the air through symbiosis with rhizobium bacteria will affect plant growth and development. The ability of a variety to fix nitrogen can greatly affect its growth and production.
Rhizobium's role in soybean growth
Rhizobium is a bacterium that lives symbiotic with legume plants, including soybeans. This bacterium is able to obstruct nitrogen from the air and convert it into a form that can be absorbed by plants. In other words, Rhizobium helps provide nitrogen, nutrition is important for plant growth and development.
Why does Rhizobium have no significant effect?
Although Rhizobium has an important role in soybean growth, the results of this study indicate that the application of Rhizobium does not have a significant effect on all observed parameters. This may be caused by several factors:
Nitrogen availability in the soil
Soil in TBM 1 rubber gawangan may have enough nitrogen available for soybean plant growth, so the application of rhizobium does not provide significant additions.
Natural Rhizobium Population
There may be a Rhizobium population that is quite abundant in the experimental land, so the application of additional rhizobium does not have a real effect.
Environmental conditions
Environmental conditions such as temperature, humidity, and pH of the soil can affect the effectiveness of rhizobium in obstructing nitrogen.
CONCLUSIONS AND RECOMMENDATIONS
The results of this study indicate that the selection of exact soybean varieties is very important to achieve optimal results in the gawangan of TBM 1 rubber plants. Although the application of rhizobium does not show a significant effect in this study, the use of rhizobium is still recommended as an effort to increase nitrogen availability in the soil and support plant growth soya bean.
Further research is needed to identify other factors that affect the growth and production of soybeans in TBM 1 rubber gawangan, such as soil characteristics, rubber plant management, and the influence of environmental conditions. This will help in determining more effective and optimal soybean cultivation strategies in the environment.
Future Research Directions
- Soil Characteristics: Further research is needed to identify the characteristics of the soil in TBM 1 rubber gawangan that affect the growth and production of soybeans.
- Rubber Plant Management: The management of rubber plants can affect the growth and production of soybeans. Further research is needed to identify the best management practices for rubber plants that support soybean growth.
- Environmental Conditions: Environmental conditions such as temperature, humidity, and pH of the soil can affect the effectiveness of rhizobium in obstructing nitrogen. Further research is needed to identify the optimal environmental conditions for soybean growth.
