Response of Nitrogen Content for Some Varieties of Kenaf Fiber (Hibiscus cannabinus L.) by Applying Different Levels of Potassium, Boron and Zinc

Abstract The aim of this study was to determine the impact of the potassium, boron and zinc on the nitrogen of fiber. Two kenaf varieties namely; FHH 925 and 4383, were planted. Fertilizers (0, 100 and 150), (0, 1.0 and 1.5) and (0 and 5.0) kg/ha, for potassium, boron and zinc were added respectively. The best result was achieved for variety FHH 925 when potassium was added at level of 150 kg/ha, but regarding 4383 was when potassium, boron and zinc were applied at 150, 1.0 and 5 kg/ha, respectively. Based on the results potassium was really suitable for the kenaf.
