%X Field trials were conducted at the University of Uyo
Teaching and Research Farm in 2009/2010 and 2010/2011 to evaluate cassava
yield, garrification traits, and economic returns as influenced by genotypes
grown in an ultisol. Uyo is located between latitudes 4°30' and 5°27'N
and longitudes 7°50'E and 80°20'E. The area, which lies within
the humid tropical rainforest zone of southeastern Nigeria, has an annual mean
rainfall of 2500 mm with a bimodal rainfall pattern, monthly sunshine of 3.14
hours, and a mean annual temperature of 28°C. The experimental site was
previously put into cultivation of some arable crops such as fluted pumpkin,
okra, and waterleaf before it was fallowed for two years. A randomized complete
block design, replicated three times was used.
Treatments were 16 cassava genotypes (AR1-82, NR02/0028, NR03/0174, CR12-45,
NR03/0211, TMS98/2132, TMS01/1206, TMS01/1368, TMS01/1371, CR36-5, NR02/0007, NR03/0155, AR37-108,
TMS01/1412, TMS30572 and local best variety ¡°Obubit okpo¡±). Results obtained via combined
(pooled) analysis of the two seasons indicated that cassava yield differed significantly
among the genotypes. NR02/0018 (42.50 t/ha) out-yielded others by 17% - 52%
followed by NR 02/0007 (35.42 t/ha), and NR 03/0155 (32.08 t/ha). TMS 98/2132
had the most preferred garrification attributes followed by NR 02/0018, NR
02/0007, and NR03/01155. NR 02/0018 genotype gave the highest economic returns
followed by NR 02/0007 and NR03/0155. NR02/0018 superseded others in yield,
garrification traits, and economic returns, which is therefore recommended.
