Mustard crop suitability mapping using analytical hierarchy process in the Imphal–Iril river sub-catchment, Manipur, India

Land suitability analysis is method for obtaining optimum utilization of naturally accessible land resources. This study aims to identify the mustard cultivation suitability potential sites in rabi season using analytical hierarchy process (AHP) in the Imphal–Iril river catchment Manipur, India. Using the geospatial approach, the assessment was conducted by using climate, soil and topography data. The findings indicate that AHP method could potentially be used to classify suitable zones for mustard cultivation. Highly suitability zones for mustard were observed in the valley portion having mild slope while moderately suitable sites were primarily found near the foothill, which have a gentle sloping topography. Not suitable zone were found mostly in the hilly regions. This assessment will helpful for cropping management option to the regional growers and the policy makers to achieve high production of mustard in the region.
