Abstract
The experiment was carried out under lyzometer condition ( salinity controlled conditions ) at Sakha Agricultural Research Station, Department of Soil Chemistry, Agricultural Research Center (ARC), Egypt during 2015/2016 and 2016/2017 seasons, to investigate the response of yields and its components to nitrogen and phosphorus fertilizers levels as well as technological characters of three flax cultivars under different saliniti levels. A split-split plot design with three replications was used. The main-plots were assigned to three flax cultivars i.e. Sakha3 (fiber type flax cultivar), Giza11 (dual purpose type flax cultivar) and Sakha5 (oil type flax cultivar). The sub-plots were allocated to some combination treatments of phosphorus and nitrogen fertilizers i.e. 45 kg N/fed. + 15.5 kg P2O5/fed., 45 kg N/fed. + 22.5 kg P2O5/fed., 55 kg N/fed. + 15.5 kg P2O5/fed. and 55 kg N/fed. + 22.5 kg P2O5/fed. and The sub- sub plots were concluded to four soil salinity levels (2, 4, 6 and 8 dsm-1). Results showed that Sakha3 cultivar significantly surpassed the other two evaluated flax cultivars producing the maximum fiber yield / plant and per fed., fiber length, total fiber percentage , fiber fineness, straw yield per plant and straw yield per fed.. in both seasons. Meanwhile, Giza11 cultivar significantly surpassed in the technical length, length of top capsule zone, number of capsules/plant, seed index , number of seeds/plant, seed yield per plant and per fed. in both seasons. However, Sakha5 cultivar significantly surpassed the other studied flax cultivars and produced the maximum values of seed oil content. All characters under study, except fiber fineness, gradually increased as nitrogen and phosphorus fertilizer levels increased from 45 kg N/fed.+15.5 kg P2O5/fed. to 55 kg N/fed.+ 22.5 kg P2O5/fed.. Maximum seed, straw and fiber yields were found with fertilizing flax plants with 55 kg N/fed. + 22.5 kg P2O5/fed.. On the contrast, increasing soil saliniti levels from 2 to 4,6 and 8 dsm-1 resulted in marked reduction in the estimated characters, in the frst and second seasons. Generally, The following can be viewed that the highest values of straw and fiber yields/plant and per fed. and fiber fineness (in the first and second seasons) were produced from Sakha3 cultivar, while the highest number of seed yield per plant (in both seasons) and seed yields per fed. (in the second season) were resulted from Sakha5 cultivar when fertilized with 55 kg N/fed.+22.5 kg P2O5/fed. under the lowest salinity level of 2 dsm-1 soil saliniti level condition.
