Hairy Indigo Seed

Hairy indigo is mainly used for grazing, and growth is sometimes accumulated to furnish high-quality grazing in the fall. Hairy indigo leaves are also nutritious for goats. Studies at the University of Florida showed that hairy indigo can produce up to 12 tons of dry matter per acre, which would contain about 20% crude protein and 50 to 60% digestibility. The leaves also contain high levels of mineral nutrients.

Product Information

Hairy Indigo (Indigofera hirsuta) is an erect-growing, reseeding, summer annual legume that may grow 4 to 7 ft. tall if not grazed. Hairy Indigo germinates in late Spring and continues throughout the Summer.  It is generally considered a late emerging plant (late May through June.)  The plant is somewhat shrubby, and stems become very woody as the plant matures. Stems and leaves are covered with short, bristle-like hairs. It is moderately resistant to root-knot nematode. Hairy Indigo adapts to sandy soils that have good drainage, and grows on land that may be too dry for other legumes. It does not grow well on soils that flood for an extended period of time. Early-and-late-flowering types have been developed, but all are now marketed as common hairy indigo.

Hairy indigo is mainly used for grazing, and growth is sometimes accumulated to furnish high-quality grazing in the fall for weaned calves or dry cows. Hairy indigo leaves are also nutritious for goats. Studies at the University of Florida showed that hairy indigo can produce up to 12 tons of dry matter per acre, which would contain about 20% crude protein and 50 to 60% digestibility. The leaves also contain high levels of mineral nutrients.

Cattle may reject hairy indigo when they are first placed in a pasture, but after one or more days, they begin grazing. After adapting to Hairy Indigo, cows and calves readily consume it. Cattle may develop sores on their feet and legs when grazing Hairy Indigo in the rainy season due to irritation of the wet skin of the cattle by the bristle-like hairs on the stems of the plants.

Plant between April and July at a rate of 5 to 8 lbs. per acre.

Establishment and management procedures are similar to those for other warm-season annual legumes. Hairy Indigo is easy to establish and requires very little management afterwards. Hairy Indigo requires soil pH of 5 to 6; the plant will not grow well or persist on acidic soils. Liming may be required to achieve the optimum pH. Depending on soil test results, it may be better to apply dolomite (which also supplies magnesium) than lime. How much lime will be needed depends on the soil type and original or native pH of the soil. Contact your County Extension agent for help on how you can test your soil and determine your liming needs. For good establishment, 15 lbs. of seed per acre is recommended. Disking, rolling or packing the soil after broadcasting the seed, will give better establishment. Establishment and production can be enhanced with application of 30 and 60 lbs. per acre of P2O2 and K2O, respectively. Inorganic nitrogen fertilizer is not required since Hairy Indigo is a legume and will produce its own nitrogen from the air. Due to its hardseededness, some seed may lie dormant in the soil for many years after being planted, and then germinate when the soil is disturbed.

To ensure that the plant reestablishes each year from seed, it is advisable to withdraw animals from the pasture or reduce grazing intensity two weeks before the plants begin to flower or in late Summer or early fall. This practice would allow some of the plants to go to seed. Grazing animals will help distribute the seeds in the pastures. The self-seeding nature of the plants is good from the forage standpoint, but it is a negative characteristic in terms of the weed potential of the plant. Consequently, vegetable and other row crop farmers often consider Hairy Indigo a weed. However, used as a cover crop or green manure crop, Hairy Indigo can effectively suppress nematodes that might otherwise seriously damage succeeding crops. Besides grazing, hairy indigo has also been used for hay and silage.

Instructions

When choosing to start a new lawn, remove old vegetation by using a de-thatcher, power rake or tiller to kill the existing vegetation. Rake or drag the area to remove debris and dead grass for a clean area. Ensure the soil is leveled and loosened to allow the seed to have good soil contact once spread on a clean seed bed.

If you have an area with heavy weed coverage, we recommend starting fresh by killing and removing the existing vegetation. If you choose to use chemicals, herbicides or fertilizers, you must check with the product's manufacturer prior to planting new seed to ensure the proper waiting period.

When overseeding an existing area, mow your lawn at the lowest setting and bag the clippingsx. Rake or drag any areas that have dead thatch or debris.
