Mucuna (Mucuna pruriens) otherwise known as velvet bean, is an all-purpose legume that has been acclaimed and valued for its medicinal and nutritional value. It is Indigenous to parts of eastern India and southern China, which means it is naturally occurring in India and has long been grown here, mostly as a crop for green manure, and traditional medicine or herbalism.

Farmers prefer Mucuna for its capability to enhance soil fertility by fixing nitrogen, while its rich L-dopa content has endeared it to the pharmaceutical sector as a prominent crop. Mucuna is cultivated worldwide for its seeds which are rich in protein and carbohydrates and host bioactive molecules.

Medicinal Properties of Mucuna

Being able to reduce oxidative stress, Mucuna is a much-valued crop in herbal medicine. All parts of Mucuna possess medicinal properties:

  • Seeds: High in L-dopa, they are a precursor to dopamine and are used in the treatment of Parkinson's disease, management of depression, and increasing male fertility.

  • Leaves: Known for their anti-inflammatory and antioxidant properties, these leaves have poultices for wound healing.

  • Roots and Pods: Traditionally used for snake bites, diarrhea, kidney disorders, etc.

Regional Suitability

Mucuna is adapted to warm, humid conditions with adequate rainfall, particularly at low altitudes of less than 1500 meters. This crop is cultivated in large areas of India, especially in Karnataka, Tamil Nadu, and Andhra Pradesh. It is globally cultivated in Asia, Africa, and Latin America. Due to the plant's tolerance of low soil fertility and drought, it is well suited to marginal lands.

High-Yielding Varieties of Mucuna

Each variety has been improved with yield, L-dopa content, and growth duration, so they can be grown under different climates and farming systems:

  • Arka Chandan 155-165 days medium-duration variety that yields 3.0-3.5 t/ha with support and 2.0 t/ha with surface culture. The medium-sized seed coated with white, it suitable conditions is under traditional and semi-arid regions. Moreover, the L-dopa content is 3.86% which amounts to 150.39 kg/ha.

  • Arka Shukla bears similarities with Arka Chandan but offers better adaptability, so it is an excellent choice for varied climatic conditions. It maintains a high quality of seed with medium bold, white seeds.

  • Medium-duration variety, Arka Charaka, yields a very good potential of 4.0-4.25 t/ha on support and 2.0-2.25 t/ha under surface conditions. Medium-sized seeds with shiny black coats and non-irritant trichomes have added advantages in handling. The L-dopa content is 4.80% and provides a yield of 200 kg/ha.

  • Arka Shubra is a high-yielding variety with a 180–190 days duration. The crop can produce 4.5–5.5 t/ha with support and 2.25–2.75 t/ha under surface cultivation. It is distinguished by its highest L-dopa content of 5.43%, yielding 269.67 kg/ha. Medium white seeds are ideal for pharmaceutical applications.

  • Arka Dhanwantri: A long-duration crop (185–190 days) with high yields of 4.2 t/ha and an L-dopa content of 190 kg/ha. Its salient characteristics are purple flowers, shiny black seeds, and no fruiting in basal nodes, which makes it suitable for specific cultivation systems.

  • Arka Aswini is a short-duration variety (120–130 days) suited for quick harvest cycles. It produces 2.31 t/ha with 3.5–4.0% L-dopa, which amounts to 80.62 kg/ha. The variety has non-irritant trichomes, fruiting in basal nodes, and black immature fruits.

Reasons for selection of variety for selective objective

Each variety possesses different characteristics, allowing farmers to avail the right option according to regional conditions, market demand, and medicinal use.

  • L-dopa Yield: Arka Shubra recorded 5.43%, followed by Arka Charaka.

  • Yield Potential: Supportated yields of Arka Shubra up to 5.5 t/ha

  • Regional Suitability: Short-duration Arka Aswini cultivar is more suitable for regions where the duration of the crop growing season is short.

  • Seed Type: Shiny black-seeded varieties are noticed in Arka Charaka and Arka Dhanwantri while others have white-seeded ones.

It is a crop that bears immense agricultural, medicinal, and economic potential. Improved varieties cater to diverse farming needs, enhanced yield, L-dopa content, and adaptability. Cultivation of these varieties will ensure sustainable practices while handling global health and nutrition challenges. Integration of mucuna into modern farming will definitely transform livelihoods and introduce agricultural resilience.
