About Locust Bean Dawadawa Yield
Estimate Your Dawadawa Yield from Locust Beans
Dawadawa (also called iru or ogiri) is one of West Africa's most prized traditional condiments, made by fermenting the seeds of the African locust bean tree (Parkia biglobosa). The transformation from raw pods to finished dawadawa involves multiple processing stages - depulping, boiling, dehulling, fermenting, and sometimes drying - each of which reduces the weight of the final product. The Locust Bean Dawadawa Yield Tool on ToolWard helps processors estimate how much finished dawadawa they can expect from a given quantity of raw locust bean pods or seeds.
The Processing Journey and Where Weight Is Lost
Raw locust bean pods consist of a sweet pulp surrounding hard seeds, all encased in a woody shell. The first major loss happens when you remove the pods and pulp - the seeds are only about 30-40% of the total pod weight. Boiling the seeds for 12-24 hours softens the hard seed coat, which is then removed by pounding and washing. This dehulling step removes another significant portion. The cleaned cotyledons are then boiled again and fermented for 2-3 days, during which some moisture evaporates. The final product can be sold wet (as fresh dawadawa) or sun-dried for longer shelf life, which causes further weight reduction.
Each stage has a yield factor that varies by seed quality, processing technique, and environmental conditions. This tool models those factors so you don't have to guess.
How to Use the Tool
Select whether you're starting from whole pods or already-shelled seeds. Enter the weight, choose the end product form (wet dawadawa or dried), and the tool walks through each processing stage, showing the yield at every step. You'll see the final estimated output alongside a breakdown of losses at depulping, dehulling, and fermentation stages.

Who Benefits from This Calculator?
Rural women processors who produce dawadawa as a livelihood activity can use the tool to determine how many bags of raw pods to purchase for a target output. In the savanna regions of Nigeria, Benin, and Ghana, dawadawa production is a vital income source, and knowing yields in advance supports better financial planning.
Commercial condiment manufacturers scaling up traditional dawadawa production use the calculator for procurement and production planning. Cooperative societies aggregating locust bean products for urban and export markets reference it when setting purchase prices for members' output. Agricultural researchers studying locust bean value chains use it as a benchmarking tool, and food science students find it helpful for understanding processing efficiency.
Practical Scenario
A women's cooperative in Niger State collects 200 kg of dried locust bean pods from community members. Before beginning the week-long processing cycle, the leader enters the weight into the Locust Bean Dawadawa Yield Tool, selects whole pods as the starting material and dried dawadawa as the target product. The tool estimates approximately 24 kg of dried dawadawa. She uses this figure to pre-sell to market traders in Minna at an agreed price, securing revenue before the processing even begins.
An entrepreneur in Ibadan importing locust bean seeds from the north for small-batch artisanal dawadawa production enters 50 kg of shelled seeds. The tool skips the depulping stage and estimates roughly 30 kg of fresh wet dawadawa or 18 kg if she opts to sun-dry the final product. She prices her branded jars accordingly.
Tips for Better Yields
Use mature, well-dried pods for easier depulping and higher seed recovery. Fresh or damp pods are harder to crack and the pulp clings to the seeds, increasing processing time and waste. During boiling, ensure the seeds are fully submerged and cooked long enough for the seed coat to loosen completely - undercooked seeds are difficult to dehull and you'll lose cotyledon fragments in the washing process.
Fermentation conditions affect both yield and quality. Maintain a warm, consistent temperature (around 35-40 degrees Celsius) and wrap the fermenting cotyledons tightly. Inconsistent heat leads to uneven fermentation and a product that spoils faster. If drying the finished dawadawa, spread thinly on clean surfaces and turn regularly for even moisture removal.
