Kenaf (Hibiscus cannabinus L) consists of various beneficial components like stalks, seeds, leaves, fibers, oils, proteins, allelopathic chemicals, and fiber strands, among other things. Despite the numerous uses of the crop, there is little or no information on optimum agronomic practices such as planting date and N fertilization of the crop in the Upper East Region (UER) of Ghana where the crop is widely cultivated by smallholder farmers. Field experiments were therefore carried out in 2020 and repeated during the 2021 cropping season in the study area. The objective of the study was to determine appropriate planting date and N fertilization for increased kenaf productivity. In each year, the treatments consisted of 3 × 5 factorial combinations of three planting dates (1st July, 7th July and 14th July) and five levels of N (0, 20, 40, 60 and 80 kg/ha) replicated three times. The design of the experiment was a split-plot with the N fertilizer as the main plot and the planting date assigned to sub plot. The results showed that, planting kenaf in early (1st) July or N fertilization at the rate of 60 kg/ha increased plant density, stem height, stem diameter, dry bast and core yields in both cropping seasons.

Aim： To determine the possible roles of the t-complex testis expressed gene 5 （Tctex5） on sperm functions, the fulllength sequence of mRNA was studied and compared in the testis between the normal wild-type and the sterile t-haplotype mutant mice. Methods： We applied rapid amplification of cDNA ends, Northern blot and reverse transcription polymerase chain reaction to analyze the full length of Tctex5 mRNAs isolated from testes of the wild-type and the t-haplotype mice. Reverse transcription polymerase chain reaction was used to semi-quantitatively compare expression of Tctex5 transcripts in the 16 tissues and 9.5 day stage embryos in the wild-type mice. E-translation was applied to estimate the amino acid sequences. Results： One long and one short transcript of Tctex5 mRNA were discovered in mouse testis of wild-type （Tctex5^long-＋ and Tctex5^short-＋） and t-haplotype （Tctex5^long-＋ and Tctex5^short-＋） mice, respectively. Being enhanced only in the testis, Tctex5^long-＋ had 17 point mutations and one 15-bp-deletion in the exon 1 region, comparing with the Tctex5^long-＋, whereas the Tctex5^short-＋ was similar to the Tctex5^short-＋. The short isoforms of Tctex5 mRNAs in the two models encoded exactly the same peptides, but the long isoforms did not. The estimated peptide encoded by Tctex5^long-＋ had significant mutations on putative sites of phosphorylation and PP1 binding. Conclusion： We established that mutations that occur in the Tctex5 long transcript of the t-haplotype mice are important for normal sperm function, whereas the short transcript of Tctex5 might have a conserved function among different tissues. （Asian J Androl 2008 Mar; 10： 219-226）
