Effect of mound size and fertilizer on white guinea yam (Dioscorea rotundata) in southern Nigeria
Field trials were conducted in the forest zone of southern Nigeria on three soil series, gravelly loamy sand Ibadan soil (Oxic paleustalf), gravelly sandy loam Egbeda soil (Oxic paleustalf) and sandy loam Alagba soil (Oxic paleustalf). The trials were carried out to study the effects of planting on...

| description | Field trials were conducted in the forest zone of southern Nigeria on three soil series, gravelly loamy sand Ibadan soil (Oxic paleustalf), gravelly sandy loam Egbeda soil (Oxic paleustalf) and sandy loam Alagba soil (Oxic paleustalf). The trials were carried out to study the effects of planting on flatversus various mound sizes and NPK fertilizer on performance of white Guinea yam (Dioscorea rotundata) cultivar Laoko.
Mound size appeared to have a more pronounced effect on tuber yield than fertilizer even on land which was in the second and third year of cropping after bush fallow. The average tuber yield for the three locations without fertilizers was 7.83 tons/ha on the flat compared with 9.44 tons/ha on large mound (about 30 cm height). With fertilizer application, tuber yields were 7.43 tons/ha on the flat and 11.30 tons/ha on large mound respectively. Total yield reduction on flat may in part be related to physical soil impedence. Planting on large mounds also resulted in longer tubers and shorter harvesting time. |
