Abstract

Objective: this study was conducted in order to study of the effects of nano particles and mycorrhiza ‎on contribution of dry matter remobilization and current photosynthesis in grain yield and some traits ‎of rye under water limitation conditions
Materials and methods: an experimental was conducted as factorial based on RCBD with three replications at the research greenhouse of , University of Mohaghegh Ardabili during 2023. The experimental factors were included ‎irrigation (full irrigation, irrigation withholding at 50% of booting and ‎heading stages), application of bio fertilizers ‏ ‏‎(no application and application of mycorrhiza) and nano particle foliar application with water as control,, nano iron foliar application, , nano silicon ,, both application nano iron-silicon ).‎
Findings: The results showed that irrigation withholding at 50% of booting stage and no application of ‎nanoparticles and mycorrhiza increased dry matter remobilization from stem and shoot (10.4 and ‎‎12.5% respectively) and contribution of dry matter remobilization from stem and shoot in grain yield ‎‎(24.6 and 28.7%) in comparison with application of nanoparticles and mycorrhiza under the same ‎irrigation level. Also, under severe water limitation, both application nano particles and mycorrhiza ‎increased leaf area index (30.5%), current photosynthesis and the contribution of current ‎photosynthesis in grain yield (29.8 and 15.2%, respectively), and grain yield (26%) in comparison with no application of nanoparticles and ‎mycorrhiza under the same irrigation level.‎
Conclusion: , it seems that application of nano particles and mycorrhiza can be ‎suggested to increase grain yield of rye under water limitation conditions. ‎
