Productivity indices for 16 soils developed under different agro-climatic regions in India were calculated by giving ratings for different limiting soil characteristics. For wheat, well drained, medium textured soils with cambic diagnostic horizons were highly productive. Saline Nanaksar, saline and calcareous Machaki Kalan, poorly drained Kapurthala, and stratified Jalalpur soils had low productivity. Kanjli, Gondpur, Sarkowal, Gulpur, Gurdaspur, Samana soils had moderate productivity. The validity of the land coefficient (LC) ratings was supported by the linear regression coefficient relating yields of wheat obtained under recommended practices, showing the reliability of soil parameters, such as drainage, texture, lime content, fertility status and salinity for soil site suitability evaluation for wheat.
