Detailed soil survey was carried out using cadastral map as base map of 1: 50,000 to identify the morphological, physical, chemical and exchangeable properties of soils and climatic parameters like moisture and temperature regimes. The classification was done up to subgroup level by following the guidelines of USDA soil taxonomy (soil survey staff, 2006). The study area falls under ustic moisture, isohyperthermic temperature regime. Pedons P1, P4 and P5 were classified as Typic Calciusterts, P3 called as Typic Duriustepts, P2 as Typic Haplustalfs whereas P6 named as Typic Plinthustalfs. Based on the analytical data, the evaluation was carried out with baseline of NBSS & LUP suitability criteria guideline for cassava, reported that P1 and P2 were considered to be highly suitable (S1) soils for cassava production, P3 and P4 falls under moderately suitable (S2) category, P5 is not suitable (N1) for tapioca cultivation whereas P6 is Marginally suitable (S3) for cassava production.
