Hypothesis
Physio-climatic, soil composition, spatial, and growing season factors will predict the selection of sorghum for cultivation.
Note
Mean of growing cycle duration, the variance of both topsoil and subsoil cation exchange capacity and the mean soil organic carbon are the main factors in determining sorghum cultivation. Physio-climatic and spatial data were not significant factors in determining sorghum cultivation.
