The objective of this study was an assessment of on-farm storage practices for Bambara groundnut and roselle grains in Niger. It is based on a random sample of 164 farmers producing both crops in the Dosso and Maradi regions using a semi-structured questionnaire. Analysis of the data used Probit regression and budgeting. Fifty four percent of respondents use some type of potentially hermetic container for storage of Bambara groundnut and 46% use that type of container for roselle. Potentially, hermetic containers include metal drums, plastic jugs, and single, double and triple layer plastic bags. About 67% of the quantity of Bambara groundnut stored was in potentially hermetic containers and 58% of roselle. Triple layer Purdue Improved Crop Storage (PICS) bags were used mainly by Bambara groundnut farmers storing larger quantities. While only about 10% of the respondents reported storing Bambara groundnuts in PICS bags. The quantity stored by those respondents is quite large, so about 39% of the total quantity of Bambara groundnut stored by the respondents was stored in PICS bags. For roselle, PICS bags were used by 4% of respondents for only 3% of quantity stored. Profitability of using PICS bags for one or two years is comparable to that achieved with the common practice of storing in woven bags with insecticide. While PICS bags use does not increase profitability substantially compared to insecticide use, it does allow the producer to reduce pesticide exposure and the associated health risks.
