Influence of NPK Fertilizer on Growth and Nutrient Uptake of Kenaf (Hibiscuss Cannabinus L.) In South Western Nigeria (Published)
A pot experiment and field trial was conducted in 2013 and 2014 respectively at Ibadan (07038’N, 03084’E 182m) Nigeria to determine the influence of NPK fertilizer applied at five different rates (0, 70, 100, 130, 160 kg/ha) on the growth and yield of kenaf in a randomized complete block design with three replications. Our data showed that highest plant height, fibre and seed yields, and macro and micro nutrient uptakes were obtained in pots and plots fertilized with 130 kg/ha but not significantly different from those with 100 kg/ha. Hence, 100 kg/ha is recommended for kenaf cultivation in Southwest Nigeria.
