Recommended Planting Rates for Lespedeza

Lespedeza is a genus of flowering plants in the legume family, Fabaceae. It is commonly used as a forage crop and is known for its ability to fix nitrogen in the soil. When planting Lespedeza, it is important to follow the recommended planting rates to ensure optimal growth and yield.

1. Seeding Rate

The recommended seeding rate for Lespedeza varies depending on the specific species and the intended use of the crop. For common Lespedeza (Lespedeza striata), the recommended seeding rate is typically around 15-20 pounds per acre. For Korean Lespedeza (Lespedeza stipulacea), the seeding rate is generally higher, ranging from 25-30 pounds per acre.

2. Seeding Depth

Lespedeza seeds should be planted at a depth of approximately 1/4 to 1/2 inch. Planting too shallow may result in poor germination, while planting too deep can hinder emergence and establishment.

3. Row Spacing

The recommended row spacing for Lespedeza depends on the intended use of the crop. For forage production, a row spacing of 12-18 inches is commonly used. This allows for adequate plant density and facilitates efficient harvesting. For erosion control or wildlife habitat purposes, wider row spacing of 24-36 inches may be preferred to allow for better ground cover and natural reseeding.

4. Fertilizer Application

Lespedeza is a legume that has the ability to fix atmospheric nitrogen through a symbiotic relationship with nitrogen-fixing bacteria in its root nodules. Therefore, excessive nitrogen fertilizer application is not necessary and can even be detrimental to Lespedeza growth. However, a balanced fertilizer containing phosphorus and potassium may be applied at planting to promote root development and overall plant vigor.

It is important to note that these recommended planting rates serve as general guidelines and may vary depending on factors such as soil fertility, climate, and intended use. Consulting with local agricultural extension services or experienced growers in your area can provide more specific recommendations tailored to your specific conditions.
