EFFECT OF SEEDING RATE ON YIELD OF SOME FLAX CULTIVARS
Two field experiments were conducted at the Agric. Exp. and Res. Cent. Fac.
Agric. Cairo Univ. during 1995/96 and 1996/97 seasons to study the influence of four flax cultivars. (Giza 6, Giza 7, Giza 8 and Riena) and seeding rates ( 40,50,60 and 70 Kg/fed) and their interaction on straw, fiber and seed yields. The experimental design was a randomized complete block design in a split-plot arrangements with four replications. The main findings of this study can be summarized as follows: cultivars were significantly different in total dry weight (TOW) at different ages. Where Giza 7 and Giza 8 were superior to the other cultivars in most instances, Riena gave the lowest TOW. TOW significantly decreased by increasing seeding rate. The highest TOW was obtained with Giza 8 x 40Kg seed/fed. Cultivars had a significant effect on technical length, straw and fiber yields/plant and per fed., harvest index % for fiber: length, percentage and fineness of fiber in both seasons and plant height in first season. Where Giza 7 was superior in the traits above mentioned except, Riena was superior in fiber. percentage and Giza 8 was superior in fiber fineness. Also, cultivars had a significant effect on number of capsules/plant. seed index, seed yield/plant and fed, harvest index % for seed and seed oil percentage in both seasons. Where Giza 8 was significantly superior to other cultivars in the above traits mentioned.
A gradual and significant increments in plant height, technical iength, fiber length as well as fiber fineness were obtained with increasing seeding rate from 40 up to 70 Kg/fed. Mean whiie, fiber percentage; straw, fiber and seed yields/fed significantly increased up to 60 Kgi fed. On the other hand, a gradual and significant reduction had occurred in number of capsules/ plant; straw, fiber and seed yields! plant, seed index, harvest index % for fiber and seed as well as seed oil percentage with increasing seeding rate up to 70 kg! fed. The data showed that Giza 8 and Giza 7x 40 Kg seed / fed produced higher straw and fiber yields / plant. Respectively. The highest seed yield / fed was obtained with Giza 8 x 60Kg seed/ fed. While Giza 7x 60Kg seed / fed produced highesi straw and fiber yie!ds/ fed.
