| Abstract |
Two experiments were conducted in calcareous soil of the farm of Nobaria Agric Res. Station during 1999/2000 and 2000/2001 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 7 and Giza 8), in addition strain L .
The result can be summarized as the following :
1 - The new 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 now 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 cultivars . Data indicated that plants irrigated 7 times out yielded those irrigated 3 times in the yields of straw yield / plant as well as per fadden by 33.05% and 26.78% . respectively; while the incrases of saad yield/ plant ( 0.27 Kg.) 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 -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/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 .
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 fines ) while new strain 1 gave the tallest fiber when did not submitted to 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 must by interesting for no. of capsules, no . of seeds / capsule as well as per plant and 1000 – seed weight improve seed yield in flax .
