GIS-based land suitability assessment of chickpea and lentil in Bangladesh
Track: Agriculture

Crop-land suitability analysis is a prerequisite to achieve optimum utilization of the available land resources for sustainable agricultural production. In this study, an attempt has been made to assess the suitability of land thereby identify the potential to expand pulse cultivation. Subsequently, perform spatial analysis to produce maps of constraints and of areas most suited to chickpea and lentil. Limitations for growing chickpea and lentil were assessed; and imposed on the attributes of terrain, soil and climate on the basis of expert knowledge. The evaluation of spatial variability is carried out in terms of suitability ratings from highly suitable to not suitable in GIS environment. Land suitability maps of chickpea and lentil growing area were produced by overlaying the climatic and soil suitability maps.
The results of this study can be used for better utilization of land and provided opportunities to harvest full potential of the crop to be grown.
