Aiboni, Aiboni, Victoria, Morphology Cultivation Organic matter soil fertility 306P The farm, management level was assessed with questionnaire and direct observation of individual farm land. Parameters considered in the land productivity index are soil depth, drainage, soil texture, surface stoniness, slope, annual rainfall, primary nutrients, organic matter, base saturation, mineral reserve and nature of clay mineral. Productivity index was developed with appropriate ranges in percentage to reflect individual factor. Soil fertility and potential productivity indices were also developed. Land productivity index range from 3.77 to 60.91 and 19.82 to 48.27 for Ibadan and Remo, respectively. Cassava yield ranged from 6.30 to 11.50t/ha and 5.23 to 7.26t/ha for Ibadan and Remo, respectively. Yam yield ranged from 3.75 to 6.00t/ha and 6.20 to 8.00t/ha in Ibadan and Remo, respectively. The wide range of indices recorded for Ibadan soils is a reflection of the complexity of the parent material. Correlation coefficients between calculated and measured yield are r = 0.81 and 0.77 for yam and cassava in Ibadan site and r = -0.95 and -0.22 for yam and cassava in Remo site. The poor correlation of yields in Remo site may be due to the greater response of these soils to management. Chi-squared analysis indicate the independence between measured and calculated yield in both sites.
