A Field experiment was conducted Experimental Station Etay El-Baroud in during two successive seasons to study the effect of four irrigation rates on growth and production of three flax genotypes (Sakha 6, Giza 11, and Giza 12). Plant growth parameters, straw yield, fiber yield and seed yield were measured and four surface irrigation rates (40% of ETo, 60% of ETo, 80% of ETo and 100% of ETo) were applied in clay soil. Results showed that the irrigation treatment had a non-significant in plant height, technical stem length, length of fruiting, number of fruiting, number of capsules per plant, number of seeds in capsules of flax in two seasons. Meanwhile length of the fruiting zone, number of seed per plant, biological yield, straw yield, seed yield and fiber yield were significant difference with irrigation rates. Water stress adversely affected theses parameters. Flax cultivars differ in flax plant growth and yield component parameters. The interaction between water stress and flax cultivars revealed that Sakha 6 was the superiority tolerant flax genotypes in comparison with Giza 11 and Giza 12. The average applied irrigation water AIW throw two seasons were 1018, 1526, 2035 and 2544 m3/fed for 40, 60, 80 and 100% ETo irrigation treatments, respectively. The irrigation water productivity (IWP) was increasing with decreasing applied irrigation water. The highest value in IWP of straw yield was in Sakha 6 under 40 % ETo while the lowest was Giza 12 under fully irrigated. The highest value of seed IWP were in Giza 11 and Giza 12. It could be recommended that planting of Giza 11 to obtain highest seed yields and Giza 12 to obtain highest fiber yields and save more water. The highest value of fiber IWP was in Giza 12, only. It concluded that flax genotypes differed in its growth and yield components under water stress conditions.

A two-year field experiment (2022–2023) was carried out to investigate the impact of different sowing periods (spring and winter) and nitrogen levels (0, 30, 60 kg/ha) on the phytoextraction potential of flax. The study site is characterized by high concentrations of heavy metals (Cd, Ni, Cu, Pb, Zn) and belongs to the Mediterranean climate type. Flax (var. Calista) was sown in the spring of 2022 and in the winter of 2023, following a split plot experimental design with three rep-lications, and applying low-input practices. Results showed that spring-sown flax produced short-er but thicker plants with significantly higher biomass (5.27 tn ha-1) when treated with 30 kg ha-1 N compared to winter-sown (2.30 tn ha-1) when treated with 60 kg ha-1 N. The concentration of contaminants in the aerial biomass varied according to metal type and sowing period. The higher biomass production in spring resulted in a higher quantity of heavy metals being removed from the soil, making flax a promising crop for phytoextraction purposes, especially in soils contami-nated with multiple heavy metals.

“…Drought-resistant species maintain more RWC in stress conditions, which can be a desirable trait in droughtresistant cultivars, which causes their openings to be tied in dry stress conditions and reduce transpiration, which affects the absorption and transfer of minerals (Wasaya et al, 2021). The higher RWC can be for two cases: these cultivars with their characteristics and by closing their stomata and less transpiration in dry stress conditions, keep their water content at high levels of water, and or these cultivars can absorb water from more deep of soil and transfer to air organs and maintain their RWC at high levels (Singh et al, 2021;El-Borhamy et al, 2022;Lotfi et al, 2022). Genotypes with higher RWC under stress conditions can have high stomata conductivity and photosynthesis and, as a result, have high drought resistance (Anwar et al, 2022).…”

IntroductionWheat (Triticum aestivum L.) is a strategic crop and one of the world's most essential cereals, providing most of the world's calories and protein needs. Drought stress is one of the main limitations for crop production such as wheat in arid and semi-arid regions. Plants can accumulate antioxidants, carbohydrates, and stress hormones that stimulate cell and molecular regeneration under stress conditions. Irrigation saves water, improves crop photosynthesis, and increases plant ability to absorb water and elements from soil. Therefore, irrigation at the right time or supplementary irrigation can help plant growth and crop yield under drought conditions. Appropriate nutrition with fertilizers increases plants' stress tolerance. Bio-fertilizers are restorative elements used in soil to improve tolerance to stresses such as drought stress. A well-known class of bio-fertilizers is plant growth promoting rhizobacteria (PGPR). These rhizosphere bacteria affect plant development and productivity by interacting with roots. Arbuscular mycorrhizal fungi (AMF) alleviate drought stress in plants by enhancing their ability to absorb water and nutrients from the soil. Seaweed extract bio-fertilizer is organic matter used to increase crop growth and soil fertility. This bio-fertilizer is utilized as growth stimulants and food supplements. Our research analyzed the effects of rhizobia and seaweed extracts on wheat's drought resistance mechanisms.Materials and methodsThis research was conducted in Iran in the crop years of 2017–2018 and 2018–2019 in the research farm of Kurdistan University Faculty of Agriculture located in Dehgolan with coordinates 47°18′ 55″ East and 35°19′ 10″ North with an altitude of 1866 meters above sea level, 45 kilometers east It was done on the wheat plant in Sanandaj city. The experiment was conducted in the form of a split-split plot in the form of a randomized complete block design with four replications. Irrigation treatments as the main factor (no irrigation or dry-land, one irrigation in the booting stage, two irrigations in the booting and spike stages), two wheat cultivars (Sardari and Sirvan) as secondary factors, and the application of biological fertilizers at eight levels including Mycorrhiza + Nitrozist and Phosphozist, Seaweed extract + Nitrozist and Phosphozist, Mycorrhiza + Seaweed extract, Mycorrhiza + Nitrozist and Phosphozist and no application of biological fertilizers (control) as Sub-sub-factors were considered.Results and discussionAccording to the study, when bio-fertilizer was applied with once and twice supplementary irrigation levels, leaf relative water content (RWC) and soluble protein content (SPC) increased, while lack of irrigation increased malondialdehyde (MDA). In both years, bio-fertilizers, especially their combinations, increased the amount and activity of enzymatic and non-enzymatic antioxidants, including peroxidase (POD), superoxide dismutase (SOD), phenol (Phe), flavonoid (Fla), and anthocyanin (Anth). Also, it enhanced the inhibition of free radicals by 2-2-Diphenyl picryl hydrazyl (DPPH) and cleared active oxygen species. It was found that malondialdehyde (MDA) levels were very low in wheat under two times irrigation with averages of 3.3909 and 3.3865 μmol g−1 FW. The results indicated a significant positive relationship between non-enzymatic and enzymatic antioxidants such as Phe, Fla, Anth, DPPH, POD, and SOD enzymes and their role in improving stress under dry-land conditions, especially in the Sardari variety. Biological fertilizers (Mycorrhiza + Nitrozist and Phosphozist + Seaweed extract) increased wheat yield compared to the control. Furthermore, Mycorrhiza + Nitrozist and Phosphozist + Seaweed extract improved grain yield by 8.04% and 6.96% in the 1st and 2nd years, respectively. Therefore, appropriate combinations of microorganisms, beneficial biological compounds, and supplementary irrigation can reduce the adverse effects of drought stress in arid and semi-arid regions.
