| Abstract | ||
| This investigation was carried out in the farm of lsmaelia Agric. Res. Station, A.R.C. during the two successive seasons 2000 and 2001 to study the effect of number of plants per hill on yield and its related characters among four kenaf genotypes. Results indicated that: the promising strain 105/16-5 recorded the highest estimates in plant height, technical length, green and fiber yield/ fad. , followed by the imported variety Tyaning . But the lowest estimates for the above mentioned characters were recorded for Giza 3 variety. Increasing number of plants / hill caused gradual increment in each of plant height, technical length, green and fiber yield / lad. also it resulted in significant decline in fruiting zone length, stem diameter and green yield/plant .Giza 3 variety ranked first in number of capsules /plant, number of seeds/ capsule, seed index, seed yield / plant as well as per fad, and the Imported variety Tyaning ranked second. The lowest estimates were recorded for S.16. Increasing the number of plants/hill caused an increase in seed yield/ faddan, while there was reduction in no. of capsules/plant, no. of seeds/ capsule and seed yield per plant. S. 105/16-3 recorded the highest estimates for fiber length, fiber percentage, and fiber fineness, while Giza 3 variety was the lowest one for the mentioned characters, and the second position in seed oil percentage after S.16. There was significant increase in fiber length, fiber percentage, fiber fineness and seed oil percentage with increasing number of plants/ hill. Correlation coefficient values were significant and positive between fiber yield and plant height, technical length, stem diameter and green yield/ plant for all kenaf genotypes, in addition to (r) value in number of capsules/plant for Tyaning variety. Significant and positive correlation coefficients were observed between seed yield/plant and (wiling zone length, no. of capsules/plant in all kenaf genotypes in addition to seed index for Giza 3 variety and S.105/16-3. | ||
