Abstract
Assessing the suitability of an area for Ag,rkcultural craps requirt: a considerable
effort in terms of information collection that presents both opportunities and limitations
to decision-makers. A DSS was dcveluped fur specified crops based an 9 criteria of
climatic requirements (average annual precipitation and annual mean temperature) and
the quality arid characteristics of land (slope, drainage, soil texture, soil depth, sail CEC,
sail base saturation, and sail pH).The Jmbi Province is the case study area. The main
objective of this study was to develop a land suitability decision support: system and to
determine the suitability classes for selected crops in study area. The methodology was
concerned to producing polygons included climatic and sail factors; scaring of each
factor coincide with requirements of each crop; grading for the suitability classes based
an the total, score and classification of each classes based on thc current land available
status. In the system, the user needs to select the most appropriate mnge of each factor
(coincide with his soil environment) in the given combo boxes, then at the end of
selection it would give the result that is Highly Suitable ($1) when the grade ($1 is equal
to I ar Moderarely Suitable (52)when 1< S < = 2 or Marginally Suitable (33) when 2< S
