Experiments were conducted at the Federal College of Agriculture, Akure in 2015 and 2016 to evaluate yield response of four improved cassava (Manihot esculenta, Crantz) varieties. The experiment was set up in a 4 x 2 x 2 factorial experiment comprising of four cassava (TME 419, TMS 98/0581, 98/0505 and 30572), two planting dates (May and June) and year of planting (2015 and 2016). Yield evaluation was done at 12 months after planting. Significant interaction was obtained between varieties and time of planting for the number of roots harvested per plot. TMS 0581 recorded the highest average number of cassava root harvested 144.8 tubers in 2016. The number of tuber rot obtained per plot was significantly influenced by cassava varieties. TMS 0505 had 24.1 tuber rot per plot in 2015. This value amount to 13.2% loss in total number of storage roots formed and subsequent lowered yield (25.21 t/ha) compared with other varieties. Similarly, higher percentage of rotten roots (10.3%) per plot was obtained for TMS 0505 in 2016. However, the root rot was only significantly lower than root yield of TMS 0581 that recorded 53.09 t/ha. The effect of time of planting was only significant for 2015 planting season. The four varieties evaluated exhibited high yield capacity under the production research plot.
