The trial on responses of cassava varieties to dry season cropping in Port Harcourt, Rivers State was conducted at the Teaching and Research farm of the University of Port Harcourt, Rivers State of Nigeria. The aim of the research was to determine the best cassava variety that can withstand drought and perform better in the dry season within the area. A complete randomized block design with three replicates on each planting date was adopted. Two cassava varieties- TMS 30572 (Brown skin) and TMS 98/0505 (Off- white skin) were used for the study due to its availability within the region. The dry season dates chosen for planting were December 21, 2010 (Dry-season); January 21, 2011 (Dry-season+ Harmattan); and February 21, 2011(Dry-season + 4 conventional rains). The result of the trial showed that the cassava variety- TMS 98/0505 is more tolerant to drought and less tolerant to the cloudiness of the rainy period in the Port Harcourt area than TMS 30572.On yield, TMS 98/0505 produced 7.0tons/ha in December, 5.52 tons/ha in January and 3.89 tons/ha in February planting, While TMS 30572 produced 5.57tons/ha in December, 5.05 tons/ha in January and 5.77 tons/ha in February. Therefore TMS 98/0505 is recommended for planting in Port Harcourt, Rivers State during the dry season period. This will bring about all year round planting of this very important crop which will lead to increased or even doubled production of cassava for domestic, industrial and export purposes.
