| Abstract | ||
| Two experiments were conducted in calcareous soil of the farm of Nobaria Agric. Res. Station during 1999/2000 and 200012001 seasons to study the effect of irrigation frequency, microelement- nutrients and their interactions on yield, yield components and quality of the two local cultivars (Giza 7and Giza 8), in addition strain L. The result can be summarized as the following: 1. The new strain 1 recorded the maximum values of seed and fiber yields per plant as well as per Fadden, while Giza 7 out yielded other flax cultivars in straw yield and recorded the highest values of fiber per-cent age and fiber fineness, but the new tested strain gave the longest fibers when compared with the other cultivars Giza 7 or Giza 8. 2. Irrigation frequency significantly affected on the all yield and its components, in addition to, fiber quality of flax cullivars. Data Indicated that plants irrigated 7 times out yielded those irrigated 3 times in the yields of straw yieldl plant as well as per Fadden by 33.05 % and 26.78% respectively; while the increases of seed yield/plant (0.27 g.) and per Fadden (159.4 Kg.) produced from plants irrigated 7 times when compared with 3 times; the maximum fiber yield per plant or per Fadden (0.481 g and 0.538 ton) were obtained from plants gave 7 time irrigations. 3. Results indicated that micronutrients application improved the all flax yield and its components, in addition to quality trails. The highest value of straw yield (4.02 ton I fed ) was obtained from new strain 1 when irrigated without deprivation and used micro- nutrients While the highest fiber yield (0.720 ton) was obtained from Giza 7 . When affected by the same previous factors; on the other hand, Giza 8. Recorded the highest yield of seed either per plant or per fed den by 0.88 g or 755.47 Kg. Respectively, when its plants did not submitted to water deprivation and treated with foliar microelements. If 4. Giza 7. Recorded the highest values for both of fiber percentage and fiber fineness when its plants treated either micronutrients and irrigated without deprivation (fiber percentage) or irrigated only three times (fiber fineness) while new strain 1 gave the tallest fiber when did not submitted fo water stress and treated with micronutrients. 5. The correlation coefficient (r) values between straw yield, seed yield or fiber yield and some related characters were recorded, the results, generally indicated that the flax breeder must give priority to selection for increasing plant height and technical stem length to increase either straw yield or fiber yield, on the other hand, must be interesting for no. of capsules, no. of seedslcapsule as well as per plant and 1000- seed weight improve seed yield in flax. | ||
