Abstract
Effects of Titanium Dioxide on The Diseases, Development and Yield of Edible CowpeaTitanium dioxide (TiO2) is being considered as a growth promoter that plays the function of antibiotics in cowpea (Vigna unguiculataWalp) production in Nigeria. Field trials were conducted at the Institute of Agricultural Research and Training, Moor Plantation, Ibadan, Nigeria in 2006 and 2007 to evaluate the influence/effect of TiO2on the development yield and diseases of cowpea. Two treatments of TiO2at 125 cc/ha significantly improved the development and yield and reduced the severity of foliar and pod diseases of cowpea compared to a single treatment at lower concentrations. Irrespective of the number of sprays and concentrations TiO2increased the yield of cowpea by 8.74-36.11%, and 10.33-51.31% respectively, in both years.
