Abstract

The study was carried out at University of Uyo, Akwa Ibom State to evaluate the performances of ten pro-vitamin A cassava genotypes under water stress condition. The experiment was 10 x 3 factorial laid out in a randomized complete block design (RCBD), replicated three times. Factor A were 10 pro-vitamin A cassava genotypes; TMS 01/1368, TMS 01/1412, TMS 01/1371, NR 07/0246, NR 07/0240, NR 07/0145, TMS 1070134, TMS 1070337, TMS 070593 and TMS 1061635 while factor B were the water field capacities (FC); 25, 50 and 75%. Growth and yield parameters were assessed. Results showed that all the cassava genotypes tested for had highest vegetative and growth parameters at 75% FC, followed by 50% FC while least at 25%. At 25%, TMS 01/1371 genotypes had the highest storage root yield kg/ha in 2012 and 2013 cropping seasons respectively, while TMS 01/1412 and NR 07/0240 had the highest potential storage root yield at 75% with the least yield at 25% FC. Therefore the study suggests that TMS 01/1371, TMS 07/0145, TMS 07059 and TMS 1061635 genotypes should be recommended to cassava growers in areas with short duration of rainfall.
