Soybean is one of the most important legume crops cultivated worldwide, accounting for over 90% of the total oilseed production. Soybean cultivation has been considered as one of the best options for sustainable agriculture due to its ability to fix atmospheric nitrogen and improve soil fertility. However, soybeans can also suffer from pests, diseases, and nutrient deficiencies, which can reduce yield and quality. One way to address these issues is through companion planting. In this article, we will discuss some of the best companion plants for soybeans that can help boost yields naturally.

Benefits of Companion Planting

Companion planting involves growing two or more plant species together in the same area, with the aim of improving crop health, productivity, and biodiversity. The benefits of companion planting include:

Pest control: Some plants have natural insect-repelling properties that can help protect other plants from pests and diseases.
Nutrient cycling: Certain plants can absorb and store nutrients that are not readily available to other plants, making them available later when needed.
Soil improvement: Companion plants can help improve soil structure, fertility, and moisture retention.
Biodiversity: Growing different plant species together can attract beneficial insects, birds, and other wildlife that contribute to the overall health of the ecosystem.

Best Companion Plants for Soybeans

Here are some of the best companion plants for soybeans:

1. Corn

Corn is an excellent companion plant for soybeans, as it provides a natural trellis for the soybean plants to climb. Additionally, corn releases volatile compounds that repel pests such as the corn earworm, which can also attack soybeans. Planting corn and soybeans together can also help improve soil fertility, as corn is a heavy nitrogen feeder, while soybeans are nitrogen fixers.

2. Buckwheat

Buckwheat is another great companion plant for soybeans, as it attracts beneficial insects such as ladybugs and lacewings that prey on pests like aphids and mites. Buckwheat also has a shallow root system that helps improve soil structure and moisture retention. Additionally, buckwheat flowers provide nectar and pollen for bees and other pollinators, which can benefit both soybeans and other crops in the area.

3. Sunflowers

Sunflowers are excellent companion plants for soybeans, as they attract beneficial insects such as bees, butterflies, and hoverflies that help pollinate soybean flowers and control pests. Sunflowers also have deep taproots that help break up compacted soil and draw nutrients from deeper layers. Additionally, sunflower leaves and stems can be used as mulch to suppress weeds and retain moisture.

4. Peas

Peas are natural companions for soybeans, as they both belong to the legume family and can share symbiotic relationships with soil bacteria that fix atmospheric nitrogen. Planting peas and soybeans together can help reduce the need for synthetic fertilizers and improve soil health. Additionally, peas have a shallow root system that helps improve soil structure and moisture retention.

5. Radishes

Radishes are fast-growing and easy to grow, making them an ideal companion plant for soybeans. Radishes have a deep taproot that helps break up compacted soil and draw nutrients from deeper layers. Additionally, radishes release volatile compounds that repel pests such as the cabbage maggot and flea beetle, which can also attack soybeans. Planting radishes and soybeans together can also help improve soil structure and moisture retention.

6. Marigolds

Marigolds are natural pest deterrents that repel many common garden pests such as aphids, whiteflies, and nematodes. Planting marigolds around soybeans can help reduce the incidence of these pests and improve crop health. Additionally, marigolds have a shallow root system that helps improve soil structure and moisture retention.

7. Basil

Basil is an aromatic herb that can repel pests such as mosquitoes, flies, and thrips. Planting basil around soybeans can help reduce pest damage and improve crop health. Additionally, basil leaves can be used for culinary purposes or to make natural insect repellents.

8. Oats

Oats are another nitrogen-fixing plant that can be grown with soybeans to improve soil fertility. Oats have a fibrous root system that helps improve soil structure and moisture retention. Additionally, oats release compounds that stimulate soil microbes and promote healthy soil ecology.

9. Garlic

Garlic is a natural pest deterrent that can help repel pests such as aphids, spider mites, and cabbage worms. Planting garlic around soybeans can help reduce pest damage and improve crop health. Additionally, garlic bulbs can be harvested for culinary purposes or to make natural insecticides.

10. Nasturtiums

Nasturtiums are ornamental plants that can also help repel pests such as aphids, whiteflies, and squash bugs. Planting nasturtiums around soybeans can help reduce pest damage and improve crop health. Additionally, nasturtium flowers and leaves can be used for culinary purposes or to make natural insecticides.

Companion Planting Tips

Here are some tips for successful companion planting with soybeans:

Choose companion plants that have complementary growth habits, nutrient requirements, and pest repelling properties.
Avoid planting companion plants that are susceptible to the same pests or diseases as soybeans, as this can increase the risk of infestation.
Plant companion plants in a way that maximizes sunlight and airflow, to prevent fungal diseases and promote healthy growth.
Rotate companion plants every season to prevent soil-borne diseases and nutrient depletion.
Use organic fertilizers and pest control methods to avoid harming beneficial insects and soil microbes.
