| Abstract | ||
| The experiment was carried out at the Farm Experimental of Sakha Agricultural Research Station (El-Hamrawy), Agricultural Research Center (ARC), Egypt through 2015/2016 and 2016/2017 seasons to investigate response of three flax cultivars to nitrogen and phosphorus fertilizers levels on yields and its components as well as technological characters under saline soil conditions. The experiment was done in a split-plot design with three replications. Where, the main-plots were allocated to three flax cultivars i.e. Sakha 3 (fiber flax cultivar), Giza 11 (dual purpose flax cultivar) and Sakha 5 (oil flax cultivar). The sub-plots were allocated to four combination treatments of nitrogen and phosphorus fertilizers i.e. 45 kg N + 15.5 kg P2O5/fed, 45 kg N + 22.5 kg P2O5/fed, 55 kg N + 15.5 kg P2O5/fed and 55 kg N + 22.5 kg P2O5/fed. The results were obtained could be summarized as follows:* Sakha 3 gave the best results other to flax cultivars under studied and produced the maximum valuesof length of technical , fiber yield per plant and per feddan, fiber length, total fiber % and fiber fineness in both seasons. Meanwhile, Giza 11 cultivar significantly superior other studied cultivars and resulted in the maximum values of diameter of stem , straw yield per plant and per feddan, length of fruiting zone, No. of capsules/plant, 1000-seed weight, No. of seeds/plant, seed yield per plant and per feddan in both seasons. However, Sakha 5 cultivar produced the maximum values of seed oil content. *Maximum numbers of all characters studied were showed from fertilizing flax plants with 55 kg N + 22.5 kg P2O5/fed, except fiber fineness in both seasons. It can be mentioned that mineral fertilizing Giza 11 cultivar with 55 kg N + 22.5 kg P2O5/fed in order to maximizing seed yield and its components and mineral fertilizing Sakha 3 cultivar with 55 kg N + 22.5 kg P2O5/fed to maximizing straw and fiber yields under saline soil conditions in Kafrelshiekh governorate, Egypt. | ||
