Although Vigna aconitifolia is an annual of only five months duration, it can be used as a pasture legume as it reseeds easily once it has been well established before being grazed.
Yields
Seed yields
Worldwide, average seed yields are only 70–270 kg/ha (Brink et al., 2006). However, in Australia and the USA, experimental seed yields could reach 2600 kg/ha (Brink et al., 2006). In Canada, yields were reported to range between 237 and 921 kg/ha. In India, yield ranged from 450 to 766 kg/ha depending on variety and P supply (Meena et al., 2010; Munro et al., 1998).
Forage yield
The yield of fresh forage is in the range of 37–50 t/ha, and the yield of hay was reported to be 7.5–18 t/ha (Baath et al., 2018; Brink et al., 2006).
Cultivation
Vigna aconitifolia seeds should be sown on a well-prepared seedbed towards the end of the rainy season, on residual moisture. The seeds can be broadcasted at a rate of 10-20 kg/ha when the crop is intended for seed production or at 7-34 kg/ha when it is grown for forage. The seeds can also be sown at 2.5-4 cm depth in rows (30-90 cm apart) at 2-5 kg/ha in pure stands. When grown as a rainfed crop in arid regions best results were obtained in India by planting equal amounts of early and late types in alternate rows. While weeding is important until a full canopy has developed, the application of fertilizer or irrigation is rare (Brink et al., 2006).
Moth bean can be grown as a sole crop or intercropped with pearl millet, sorghum or other cereals, occasionally with pulses. It is also grown as a green manure in rotation with cotton. Moth bean is sensitive to several viruses, fungi and nematodes. It can also be invaded by Striga spp. (Brink et al., 2006).
Harvest
Because of their prostrate habit, moth bean plants are difficult to harvest with a mower and are mainly cut with a sickle, left to dry for one week, then threshed and winnowed (Brink et al., 2006).
Storage
The seeds are prone to bruchids (Callosobruchus spp.) attacks during storage (Brink et al., 2006).
