Effect of sowing date and genotypes on some yield components of kenaf

A study was conducted at the University of Gezira in Wad Medani experimental farm in Sudan during May - September 2014 to determinate the optimum date for sowing kenaf (Hibiscus cannabinus L.). Two kenaf genotypes, i.e., GS and RS were used in the study. The experiment was designed as a randomized complete block (RCBD) and arranged as a split-plot with genotypes making main plot treatments and sowing date as sub-plot treatments. The effect of genotype on agronomic performance was not significant. Results showed that the first sowing resulted into higher plant height and stem diameter compared to the second. Days to 50% flowering were 130 compared to 110 for the second planting. The earlier planting date is thus recommended for Sudan.
