| Abstract: | Climate change, along with decreased and irregular rainfall patterns, has greatly impacted cereal production systems like barley in semi-arid areas. The adoption of climate-resilient management strategies, including effective supplemental irrigation methods and the external application of stimulants of tolerance to abiotic stresses, can prove advantageous. A field study was aimed to assess the effects of foliar application of titanium nanoparticles across three irrigation strategies—rainfed, supplemental irrigation, and full irrigation on the grain yield of seven barley genotypes in a region of northern Ardabil, northwestern Iran. Compared to rainfed conditions, supplementary irrigation and full irrigation enhanced grain yield by 12% and 28%, respectively. The application of titanium nanoparticles via foliar spraying resulted in an average increase of 70 kg ha-1 in grain yield compared to the control group. The highest grain yield (3816 kg ha-1) was observed in the G7 genotype, which sprayed with titanium nanoparticles under optimal moisture levels, while the lowest yield was noted in the G1 genotype without irrigation and nanoparticle application (1386 kg ha-1). The G7 genotype displayed the most significant response to supplemental irrigation. Additionally, the G7, G6, and G4 genotypes demonstrated a marked response to the application of titanium nanoparticles. These genotypes exhibited superior biomass and improved dry matter partitioning in economically important organs. Overall, the findings indicated that foliar application of titanium nanoparticles and the use of supplemental irrigation in conjunction with the high-yielding and tolerant genotypes G7, G6, and G4 can effectively support the barley production systems in semi-arid regions. |
