| In order to determine the response of some flax genotypes; Sakha 3, Giza 10, Strain 22, Imported and Sakha 1 under various sowing dates i.e. optimum sowing date (1st November), late sowing (21st November) and very late sowing (15th December), two field experiments were carried out at the Experimental Farm of Gemmeiza Agriculture Research Station, Agricultural Research Center (ARC), Egypt, during 2012/2013 and 2013/2014 seasons. The experiments were carried out in a split-plot design with three replicates. The main-plots were assigned to sowing dates. While, the sub-plots were allocated to flax genotypes. The main obtained results of this study were sowing flax in the first of November produced the highest values of total plant height, technical length, stem diameter, biological yield/fed, straw yield/fed and long fiber yield/fed in both. Sowing flax in 21st November resulted in the highest values of number of fruiting branches, number of capsules/plant, number of seeds/capsule, straw yield/plant, seed yield/plant and seed yield/fed in both seasons. Delay sowing date of flax until 15th December registered the lowest values of total plant height, technical length, stem diameter, number of capsules/plant, straw yield/plant, seed yield/plant, biological yield/fed, straw yield/fed, seed yield/fed and long fiber yield/fed in both seasons. Giza 10 cultivar recorded the highest values of total plant height, technical length, straw yield/plant, biological yield/fed, straw yield/fed and long fiber yield/fed in the two growing seasons. Whereas, Strain 22 genotype produced the highest values of number of fruiting branches, seed yield/plant and seed yield/fed in the two growing seasons. From obtained results, maximum straw yield and long fiber yield/fed and it`s components of flax could be achieved by optimum sowing of Giza 10 cultivar in the first of November. However, maximum seed yield/fed and it`s components resulted by late sowing Strain 22 genotype in 21st November. | ||||
