Hypothesis

Physio-climatic, soil composition, spatial, and growing season factors will predict the selection of finger millet for cultivation.

Note

Mean subsoil sulphur content, mean precipitation concentration index, and topsoil mean phosphorous content were the biggest factors in determining finger millet cultivation. Spatial data and growing season did not play a significant role.
