Narrative
US-1138 has a vigorous, indeterminate-type plant habit, a relatively short photoperiod (flowering does not begin until day length is approximately 13 hours), is resistant to the southern root-knot nematode [Meloidogyne incognita (Chitwood) Kofoid and White], does not produce seeds with impermeable seed coats, grows well without nitrogen fertilization, and is a high biomass producer. US-1138 is homozygous for all important agronomic traits. A typical pod is 20 cm long with 18 seeds. Coats of dry seeds have a smooth texture and a buff to brown color. Seed size is small with a weight of 12.6 g per 100 dry seeds, and dry seeds have an ovoid shape. US-1138 plants grown for 12 weeks without competition from neighboring plants reach an average height of 52 cm, shoot dry weight of 1.4 kg per plant, and plant spread of 2.7 m with high twining vine production. Iron Clay and other forage-type cowpea genotypes produce seeds with an impermeable seed coat, a trait that enables viable seeds to overwinter in soil, germinate the following spring, and become a weed in subsequent crops. The adoption of US-1138 for use as a cover crop will eliminate the weed problem caused by "dormant" cowpea seeds. US-1138 should be particularly useful to researchers interested in developing improved sustainable and organic agriculture cropping systems that utilize cover crops or cover crop mulches. The cowpea is desirable as a cover crop because it is tolerant of heat, drought and poor soils, grows vigorously, and competes well against weeds.
