Key takeaways

The ICAR-Central Arid Zone Research Institute (CAZRI) introduced four drought-resilient moth bean varieties (CAZRI Moth-4, 5, 6, and 7) that showed high tolerance during the Kharif 2026 El Niño period.
Moth bean (Vigna aconitifolia) is a highly resilient pulse crop cultivated across the Thar Desert in Rajasthan, Gujarat, Haryana, and Punjab.
The crop begins flowering within 30 days of sowing and survives heat exceeding 40°C in poor sandy soils.
Moth bean forms a symbiotic bond with Rhizobium bacteria to naturally fix atmospheric nitrogen while providing high-protein fodder called pala.

The ICAR-Central Arid Zone Research Institute (CAZRI) developed four new moth bean varieties called CAZRI Moth-4, 5, 6, and 7. These varieties showed remarkable survival performance during an El Niño year in Kharif 2026.

Moth bean, scientifically named Vigna aconitifolia, is also known as mat bean, Turkish gram, or dew bean. This crop belongs to the Fabaceae family and stands out as a highly drought-resistant annual legume grown in hot dry areas of South Asia.

This crop is native to South Asia and grows mainly in rainfed desert areas. Farmers cultivate it extensively in the Thar Desert of western Rajasthan, along with parts of Gujarat, Haryana, and Punjab.
The plant thrives in extreme weather with erratic rain, poor sandy soil, low organic matter, and temperatures going above 40°C.

Drought and Heat Resistance: The plant uses deep taproots to absorb moisture from deep underground soil during long dry spells.
Soil-Covering Growth: Its spreading mat-like canopy holds loose sand, lowers water evaporation, prevents wind erosion, and keeps root soil moist.
Growth Flexibility: The crop starts flowering within 30 days of sowing and adapts its growth cycle based on available soil water.
Nitrogen Fixation: Root nodules work together with Rhizobium bacteria to capture atmospheric nitrogen and restore soil fertility naturally.
Strong Pod Production: The plant forms clusters of small pods filled with protein-rich seeds and keeps its green leaves even when topsoil becomes extremely dry.

It supplies essential protein, amino acids, and minerals to poor desert communities while supporting local food industries.
The crop provides nutritious dry and green fodder called pala for livestock during dry post-monsoon months.
It supports dryland crop rotation and dune stabilization, helping India boost pulse production amidst climate change.
