Cowpea: The Untapped Potential of Northeastern and Central-Northern Brazil

The feijão-caupi — also known as feijão-de-corda, feijão-de-praia, or feijão macaçar — is the most cultivated legume in the Northeast and North of Brazil, the basis of millions of families' diet and one of the crops with the greatest potential for enhancing family farming in semi-arid regions.

Brazil produces over 700 thousand tons of feijão-caupi per year, with the Northeast accounting for more than 70% of the national production. The crop adapts to poor soils and dry periods, becoming one of the few viable productive alternatives for the semi-arid. The growing demand for premium versions of feijão-caupi — dry, green, canned, processed as protein flour, and as an ingredient in artisanal Northeastern cuisine — opens up poorly explored national and international markets.

When feijão-caupi is enhanced with certification, processing, and formal marketing channels, this segment can significantly contribute to job and income generation in Brazil.

Participate in our strategic actions to implement the best solutions in the Brazilian agricultural sector. Our activities, studies, and advanced research cover 20 chains and 255 segments of national agribusiness — from the grain chain to sustainable extraction, including horticulture, fruit growing, livestock, and much more.

The Innovation for Brazil to Produce More series was developed specifically to identify and implement the best solutions available in Brazil and around the world across the 255 segments of the agribusiness sector — with accessible technical language, updated data, and a focus on practical results for producers, suppliers, governments, and marketers.

1.  Opportunities for Small Rural Producers

How to produce high-quality feijão-caupi, access differentiated markets, and move from subsistence

Feijão-caupi is a crop with very low production costs — it adapts to poor soils, tolerates drought, and can be cultivated with minimal inputs. The significant income increase lies in the quality of the grain — selected feijão-caupi, with good coloring and no defects, is worth double that of low-quality products in cooperatives and regional supermarkets.

✔    Use of improved varieties: BRS Guariba, BRS Novaera, and BRS Tumucumaque — productivity 40 to 80% higher than local varieties

✔    Inoculation with Bradyrhizobium specific for caupi — reduces nitrogen use and increases productivity without raising costs

✔    Planting at the beginning of the rains with correct spacing — crucial for the visual quality of the grain

✔    Manual or semi-mechanized harvesting to preserve grain integrity — intact grain is worth 30 to 50% more

✔    Access to PRONAF Semiárido and Garantia-Safra for protection in years of severe drought

The E-Book 01 — Strategic Manual for the Small Rural Producer presents, in detail, the best solutions for this segment and other 254 of Brazilian agribusiness — focusing on method, cost reduction, and progressive growth from Agro 1.0 to Agro 6.0.  Access now for BRL 99.00 →

2.  Opportunities for Micro and Small Local Suppliers

What opportunities does the feijão-caupi chain offer for local technology and service suppliers

The feijão-caupi chain presents a significant need for technology and qualified services — representing a broad opportunity for suppliers who understand the specificities of the semi-arid region and family farming in the Northeast.

Solutions by area of engineering applied to the segment

Our activities, studies, and advanced research cover six major areas of engineering — and the chain requires solutions in all of them:

Electrical Engineering and Computing — solar pumping systems for emergency irrigation and rural electrification in isolated properties;

Electronic Engineering and IoT — soil moisture sensors for irrigation management and low-cost weather stations;

Control Engineering and Automation — planters and harvesters adapted to the semi-arid; small-scale processing systems;

Mechatronic and Robotic Engineering — portable threshers and small classifiers for family cooperatives;

Renewable Energy Engineering — solar photovoltaic for pumping cisterns and desalinating water — essential for any crop in the semi-arid;

Data Science and Artificial Intelligence — personalized climate alerts, drought risk mapping, and digital ATER platforms for the semi-arid.

✔    Emergency drip irrigation systems — low operational cost and essential to ensure harvests in irregular years

✔    Portable processing equipment for cooperatives — threshers, classifiers, and small-scale packers

✔    Solar energy for pumping and processing — the most impactful solution for family farming in the semi-arid

✔    Plate cisterns and underground reservoirs — rainwater capture technologies with high and permanent demand

✔    Technical assistance in inoculation and management of caupi — a service that is rarely offered but highly demanded by family producers

3.  Opportunities for Municipal Governments

How semi-arid municipalities can transform feijão-caupi into a vector for social and economic development

For municipalities in the Northeast and North of Minas, feijão-caupi is not just a crop — it is the basis of food security and rural income. A municipal manager who invests in the caupi chain invests in the retention of families in the countryside and in the endogenous development of the territory.

✔    PNAE with feijão-caupi from local family farming — guarantees institutional market for up to 30% of municipal production

✔    Implementation of plate cisterns and community reservoirs — increases resilience of production in years of drought

✔    Program for subsidized improved caupi seeds — annual distribution via EMATER and local cooperatives

✔    Support for the formation of processing and marketing cooperatives — adds value to the feijão before it leaves the municipality

✔    Municipal IDM: caupi as an indicator of food security and climate resilience of local family farming

The E-Book 03 — Reference Guide for Municipal Governments presents step by step instructions for secretaries and municipal managers to implement effective public policies for all 255 segments of agribusiness.  Access now for BRL 99.00 →

4.  Opportunities for Small Agricultural Product Traders

How feijão-caupi creates business opportunities for local traders, processors, and distributors

Feijão-caupi is much more than the "feijão-de-corda" sold in bulk at Northeastern markets. In big cities and international markets — especially in Africa and the Middle East — it is recognized as a legume of high nutritional value, rich in protein, fiber, and antioxidants. A trader who understands this positioning can sell regional feijão-caupi with a margin much higher than the commodity product.

Fresh or frozen green feijão-caupi is especially valued in the gourmet market and school meal programs. A box of fresh green feijão-caupi sold at the market for R$ 3 is equivalent to R$ 30/kg — while dry feijão is sold at R$ 5/kg. Knowing the most profitable presentation forms of the product is the first step to multiply the margin without raising costs.

Products with high commercial potential

The main derivative products from this segment for local retail and foodservice:

Selected packaged dry feijão-caupi— a product of high consumption in the Northeast and North; type 1 version with identified origin is worth 50 to 80% more than bulk products;

Fresh and frozen green feijão-caupi— a premium product for gourmet markets, restaurants, and PNAE; margin 4 to 8× higher than dry feijão;

Canned feijão-caupi— ready for consumption; expanding urban market; ideal for e-commerce and subscription baskets;

Protein flour from feijão-caupi— market for supplements and functional food; emerging niche with growing demand in major cities;

Acarajé and frozen acarajé— gastronomic product with a Northeastern cultural identity; national and international gourmet market;

Roasted feijão-caupi snacks— niche for healthy snacks; expanding market of R$ 500 million/year in major retail chains.

Trader profiles and their specific opportunities

✔    Northeastern street vendors: selected green and dry feijão-caupi — a product with a very high regional identity and margin superior to the commodity

✔    Interior grocery stores and warehouses: packaged feijão-caupi with origin — retains local customers and accesses regional supermarkets

✔    Northeastern restaurants: feijão-caupi as a main ingredient in regional dishes — authentic gastronomic differential

✔    Natural products stores: protein flour and organic feijão-caupi — premium niche with accelerated growth in major cities

✔    Distributors and wholesalers: type 1 dry feijão-caupi for supermarket chains — recurring volume with distribution margin

✔    Digital platforms: certified origin feijão-caupi and producer's story — product with high engagement in natural e-commerce

Growth strategies for local traders

The most efficient strategy for Northeastern traders is direct access to family producers via cooperatives — eliminating intermediaries and ensuring a product with identified origin, traceability, and acquisition cost 20 to 40% lower than conventional distributors. Feijão-caupi with the producer's story, the name of the cooperative, and region of origin sells 2× faster in premium retail than the product without information.

The CrediAmigo from BNB is the main credit line for small traders in the Northeast — without collateral, with quick approval and guidance from the credit agent. The Agroamigo complements for those who also produce or process. Together, these programs allow Northeastern traders to structure working capital and basic equipment with accessible credit costs.
