| Abstract | ||||
| Two field experiments were conducted, during the two consecutive seasons of 2002/03 and 2003/04, in the experimental Farm, Fac. of Agric. Fayoum Univ, El-Fayoum Governorate, to study the effect of three planting dates (30th Oct., 15th Nov., and 30th Nov.) and three seeding rates (40, 60 and 80 kg / fed) on the yield and quality of two flax varieties (Sakha 1 and Sakha 2). Split - split plot design with four replication was used. The results indicated that highest yield and yield components were produced from sowing flax on 15th Nov., while the lowest values of these traits were produced from sown on 30th Nov. Increasing seeding rates from 40 to 80 kg seed / fed increased significantly plant height, technical stem length and seed oil percentage. In contrast, main stem diameter, straw yield / plant, number of capsules per plant, seed index and seed yield / plant were decreased by increasing seeding rate. Sakha 1 variety recorded the tallest plant height, straw yield per plant and per fed, while Sakha 2 variety gave the highest number of capsules / plant, seed yield / plant as well as fed, seed index and oil percentage. In general, it could be summarized that highest fiber and seed yields per unit area was recorded by Sakha 1 and Sakha 2 varieties, respectively, with increasing seeding rates from 40 to 80 kg seed / fed. | ||||
