Growers of yam demarcate certain areas as being suitable for yam culture and the factors responsible are suspected to relate to both prevailing soil and aerial environments. No empirical evidence to substantiate this suggestions has been documented. Two popular cultivars were selected from each o...
The relative changes in the composition of six cultivars of white yam (Dioscorea rotundata Poir) were investigated in three major yam ecozones in southeastern Nigeria. The component parameters measured were crude protein, starch and total soluble sugar of the six cultivars at maturity. Each of th...
Micronutrients content in a cleared forestland continuously cropped for seven years with cassava, maize, pigeon pea and their combinations and subsequently fallowed for eight years were monitored in this study in order to determine the availability of these nutrients after these years. Soil sampl...
The contributions of soil variables to the variations in the yields of cassava (Manihot esculenta), yam (Dioscorea rotundata), maize (Zea mays) and pigeon pea (Cajanus cajan) were evaluated over 2 years in this study. The data were from three replicates of two randomized complete block design exp...
The soils of major cassava-growing areas of Nigeria were sampled at 0-20 and 20-40 depths in 1991. The objectives were to compare the nutrient levels in both cassava fields and other arable crop fields and relate their nutrient levels to possible factors that affect them. Approximately 470 sample...
Several cassava genotypes were observed although there were few bred varieties. The wide diversity in the cassava landraces was a consequence of the action of the farmers in continuously abandoning and introducing cultivars into their system as they tried to select those cultivars that met their ...
