RESULTS AND DISCUSSION
Soil Properties
Interpreted physico-chemical property data of soil at the experimental site as contained in Table 1 revealed that the soil has sandy loam texture and moderately acidic. Although these two properties are suitable for the growth of the cassava crop, all other major chemical properties analyzed for, such as total nitrogen (N), available P and K and organic carbon are low (Anonymous, 2010). This is an indication of low fertility and therefore the crop is likely to respond to fertilizer application as reported by Kang and Okeke (1991). Though differences in these soil fertility parameters were observed between the two cropping cycles, the results were not significantly different. This suggests that soil nutrient mining by the crop was minimal.
