The effects of soil amendment with basal dose of nitrogen (60 kg ha- 1), phosphorus (30 kg ha-1) and potassium (75 kg ha-1) for Yams Dioscorea species in South West Nigeria and calcium carbonate were assessed on yield and susceptibility to two storage rot pathogens, in Dioscorea alata TDa 92-2, D. rotundata TDr 131 and D. esculenta TDe 89-1. The study site at the Teaching and Research Farms of the Federal University of Agriculture, Abeokuta, had been monocropped to yams without fertilizer for three years before the study. A 3 by 5 factorial desgn, with the Dioscorea species as main plots and 0 kg ha-1, 2 kg ha-1, 4 kg ha-1, 6 kg ha-1 and 8 kg ha-1 calcium carbonate as subplot treatments, was used in each of two years. Aspergillus niger van Tiegh. and Botryod... view more»
