Effects of Planting Year and Genotypes on the Seed Yield of Kenaf (Hibiscus cannabinus L.)

Field experiments were carried out in 2014 and 2015 to assess the growth and yield of some kenaf (Hibiscuss cannabinus L.) genotypes in Aluu, Ikwerre Local Government Area of Rivers State in South-East Agro-Ecological Zone of Nigeria. The experiment was laid out in a randomized complete block design with year as main factor and genotype as sub factor in three replications. The 16 genotypes used were: G452⁴; AU72; CUBA 108; IFEKANDI 400; TAINING I; TAINING 2, IFEKAN 400; A-60-28²; V-I-400; EX-GIWA; 5108-14-47⁸; AU-75-(41*), A2-60-2826; AU-245(4^A); 2QQ(1³) and local line. Data were collected on the growth and yield attributes of kenaf genotypes. Combined Analysis of variance showed that year had a significant (P<0.05) effect on kenaf yield with year 2014 having the best performance. The genotypes vary highly significantly (P<0.001) in their performance for all the traits studied with local line having the best performance for seed and fiber yield.
