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.
