Can the Inherent Antioxidant in Yellow-Fleshed Cassava Varieties (Manihot esculenta Crantz) and Fertilizer Application Suppress Root Rot?

Cassava root rot disease has been reported to cause huge losses of fresh yield particularly when harvesting is delayed. The improved yellow-fleshed cassava varieties naturally contain antioxidant whereas widely used control plant diseases in the tropics. experiment was carried out at Federal University Agriculture, Abeokuta, Nigeria 2013/2014 and 2014/2015 cropping seasons investigate: 1) possibility inherent yellow fleshed tuber disease, 2) role fertilizer application on incidence 3) delay tubers and, yield. laid randomly completed block design arranged a split-split plot replicated three times. main plot, subplot sub-subplot treatments were four varieties, 5 nitrogen levels, 4 potassium levels. harvested 14th month produced lowest rot, longest highest 2014/2015. TMS 98/505 (white-fleshed cassava) variety had rot. positive correlation with girth, number tubers, length negative 14 16th months 2014/2015, respectively. It concluded that white-flesh could not be delayed beyond MAP, but can further 16 MAP. Besides, study affirmed white-fleshed suggesting minimized incidence. However, do seem influence root.
