Hypothesis
Physio-climatic, soil composition, spatial, and growing season factors will predict the selection of pearl millet for cultivation.
Note
Variance of temperature seasonality, variance of topsoil volumetric water content at 33 kPA, mean subsoil gravel content, mean topsoil clay content, mean duration of the growing cycle, mean temperature of the wettest quarter, variance of topsoil organic carbon content, variance of topsoil silt content, and mean temperature during the driest quarter. Spatial data played a relatively insignificant role.
