| Abstract | ||||
| The effect of four hill distances 10,15,20 and 25 cm. which represented the four population densities 86 666, 57 777, 43 333 and 34 666 plants/fed. respectively, on yield and some agronomic characters of three kenaf genotypes were studied. Experiments were conducted in 1995 and 1996 seasons at Ismaillia Agric. Exp. Station, Egypt. The results indicated that genotype S. 51/61-3 significantly surpassed the other genotypes in number of capsules/plant, green stalk yield, seed yield/plant and biological yield. It also produced fiber that recorded the highest highest values with regard to all the technological traits studied except fiber fineness, which was highest for cv. Giza 3. Narrow hill distance (10cm) resulted in lower yields per plant than 25 cm hill distance for the three genotypes. Stem diameter was 1.499cm for the lowest plant population and decreased to 0.987 cm for highest population. Results showed that kenaf sowing at density of 4333 plants/fed. using 15cm hill distance consistently produced greater green stalk yield as well as seed yield per fed by 11.76 and 0.223 ton, respectively. Plants sown at 10cm hill distance produced taller technical stem length with finer fibers. The maximum of fiber yield/fed. was obtained from plants planted at 15 cm hill distance (43333 plans/fed). Correlation coefficient were computed between green stalk yield/ plant and each of total length, stem diameter, fiber yield/plant, fiber %, length, fiber fineness and seed yield/plant. The results were significant and positive in traits of total length, fiber yield and seed yield/plant, and insignificant and insignificant and positive with regard to stem diameter. On the other hand, correlation was negative and significant with fiber fineness and negative and insignificat with fiber %. | ||||
