p.459-467. In order to mitigate the salinity effects on flax grown on saline soil, two field experiments were carried out at Horticultural Sakha Agriculture Research Station(El-Hamrawy Farm), Kafr EI-Shiekh Governorate, Egypt, during 2014/2015 and 2015/2016 seasons to study the effect of different seeding rates(50, 60 and 70 kg flax seed fed'l) and potassium fertilizer levels(O, 12, 24 and 36 kg KzO fed'l) on growth, yield and its components of flax cultivar Sakha3 under saline soil conditions. The experiments were carried out in a split-plot design with four replications. The main-plots were assigned to seeding rates. The sub-plots were randomly allocated to potassium fertilizer levels. The obtained results showed that sowing flax with 50 kg flax seed fed'] recorded the highest values of chlorophyll a in the first season, total chlorophyll and stem diameter in both seasons, whereas, sowing flax with 70 kg flax seed fed'l recorded the highest values of technical length, straw yield/fed, number of capsules/plant, seed yield/fed, fiber length, fiber yield/plant and fiber yield/fed in the two growing seasons. However, sowing flax with 60 kg flax seed fed,1 recorded the highest values of seed index in both seasons. All growth characters and photosynthetic pigments, straw, seed and fiber yields and its components of flax were gradually increased as a result of increasing potassium fertilizer levels trom 0 to 12, 24 and 36 kg KzO fed-l in both seasons. It could be recommended sowing flax with the highest seeding rate(70 kg flax seed fed-I) and fertilizing with 36 kg KzO fed-] is the best practice in order to maximize flax growth, yields and its components under saline soil conditions in KafT El-Shiekh Governorate, Egypt.
