| Abstract | ||||
| This investigation was carried out at Gemmeiza Agricultural Research Station, Gharbia governorate , ARC, Egypt during the two succesive seasons of 2006 and 2007. The aim of this investigation was to study the effect of different harvesting dates i.e.,120 ,150 and 180 days from sowing on the yield and it's related characters among eight Kenaf genotypes. The kenaf strain 158/2/4 achieved highest estimates for plant height, technical length,fruiting zone length,stem diameter, green stalk yield/plant as well as per faddan and fiber yield/fed., while the commercial variety Giza 3 recorded lowest estimates for these characters previously mentioned. On the other hand, Giza 3 ranked first and surpass all remain kenaf genotypes in seed yield and its components in addition to fiber fineness. Remarkable increment occurried by delaying harvesting date at the third one (180 days from sowing) for green yield and its related characters, seed yield and its components, in addition to fiber length and fiber percentage. Meanwhile, the second harvesting date (150 days from sowing) performed maximum averages for fiber yield/fed., percentages of either fiber and seed oil. The interaction between kenaf genotypes and harvesting dates had a significant effect on all studied characters. Key wards: Kenaf, Hibiscus cannabinus,Genotypes, harvesting Dates, Bast fibers, Technical length, fineness, oil percentage. | ||||
