In the present study, land suitability evaluation has been carried out for rice in Tirora tehsil of Gondia district, Maharashtra, through analysis of landforms and soils using IRS–ID LISS-III and ancillary data Geographic Information System (GIS). Thirteen distinct landform units have been delineated in the area . The slope of the tehsil varied from level to nearly level (0-1%) to very steep slopes (>50%). The soils occurring on different land form units been studied and horizons wise soil samples were characterized and classified. The soil depth varied from very shallow (10-25 cm) to very deep (>150 cm) and soil texture ranged from clay loam to clay depending upon topographic positions. The land evaluation criterion of FAO has been followed to assess the land suitability for rice. The suitability analysis indicates that about 45.5% of total geographical area (TGA) is highly suitable, 24% is moderately suitable and 24.2% o is not suitable for rice cultivation in the tehsil.
