Abstract A Comparative study on soil suitability evaluation guidelines for selected community crops was carried out in Khana Local Government Area of Rivers State, Southern Nigeria. Eight soil mapping units were recognized and appropriate suitability guidelines specific for each of the community crop of interest were followed in establishing the suitability of the soils of Khana for their cultivation. Various suitability evaluation guidelines of each soil type and each of the different community crops pedon by pedon, were ranked and the rankings were compared using the Spearman’s rho ranking correlation coefficient to ascertain the guidelines that can best accommodate the eight community crops of interest. The results showed that, the suitability guidelines for oil palm correlates with cassava, yam and citrus, while cassava correlates with yam and oil palm and yam correlates with cassava and oil palm. Plantain stands on its own; while the suitability guidelines to be used for maize, fluted pumpkin or okro depends on individual choice as any of the guidelines could be used for their suitability evaluation.
