Cropping Systems & Resource Management

The Cropping System & Research Management Program is the oldest and the largest program at the Institute. It cuts across all other programs with three primary research interests: 

  • Soil Fertility Management, 
  • Soil and Water Management, and 
  • Cropping Systems Research

The program develops sustainable farming systems for each agro-ecological zone in The Gambia. The program focuses on improving the sustainability of agricultural systems by:

  • Reducing external inputs, 
  • Improving utilization of internal resources, and 
  • Increasing the use of natural, sustainable methods. 

To achieve this, the program selects improved or locally grown varieties and develops higher yielding production and management practices suited to these varieties. 

Examples are:  

  • Improved land and water management, 
  • Input reduction, 
  • Better management of inherent soil fertility, and 
  • Better, more efficient use of applied soil amendments.

Achievements:

  • Identified optimum planting dates for major crops,
  • Identified optimum plant densities for major crops,
  • Developed fertilization packages for major crops,
  • Developed weed management packages for the upland and lowland crops, and
  • Developed appropriate inter-cropping practices.
