Grain Legumes & Oil Seed (GLOS)

The Scientists of the GLOS program work with: 

  • Groundnuts, 
  • Sesame, 
  • Cowpeas,  
  • Cotton,
  • Sunflower, 
  • Soya bean, and 
  • Bambara groundnuts. 

These crops are important, particularly for resource- poor farmers.  NARI scientists perform adaptive research at strategic locations around the country with emphasis on varietal screening for comparative yield performance and adaptability. This agronomic work includes moderate crop improvement efforts before handing over superior, released varieties to the NARI Seed Technology Unit for further multiplication and eventual adoption by farmers. 

Here are some of our achievements:


Over the years, there has been a decline in both the production of groundnut and the price on the world market. The decline in production and productivity are due, in part, to cultivation of the traditional long-cycle variety particularly during drought years. However, over the past few years, our program has been able to release a few improved, short-cycle varieties that are high-yielding and well adapted to Gambian ecologies. 



The screening of this crop started in the mid 1980s. Over the years, many varieties have been tested, both on-station and on-farm, and have been released to farmers. 


The local long-duration variety is still performing well. But our research work has identified other, equally high-yielding varieties that are short-cycled.
