Abstract

In order to investigate the effect of fertilizer application with chemical fertilizers and iron and zinc nano-Chelates on chlorophyll concentration, light utilization efficiency and grain yield of two bread wheat cultivars, a factorial experiment based on a randomized complete blocks design with three replications was conducted in the field research of Jihad Agriculture Center of Zarrin Abad Center during 2016-2017 cropping year. Experimental factors included seven levels of spraying (control, spraying with Iron chelate, iron nano chelate, Zinc sulfate, zinc nano chelate, Iron chelate + Zinc sulfate and nano Iron chelate + zinc nano chelate) and second factor two wheat cultivars (Chamran and Koohdasht). The results showed that foliar application with iron fertilizers and Zinc sulfate had a significant effect on chlorophyll concentration and maximum leaf area index at 1 and 5 percent probability levels, respectively. The maximum leaf area index at the statistical level of 1 percent in Koohdasht cultivar was 21. 7 percent higher than Chamran cultivar. Foliar application with nanochelates of iron with zinc nano chelate has reached the maximum dry matter accumulation (782 gram per meter square). The least dry matter was obtained at 681 gram per meter square in control plants (non-spraying). In Chamran cultivar, the maximum amount of radiation use efficiency was 30. 2 gram per mega Joule with the use of iron nano chelate, which was 27. 10 percent more than control plant. The highest amount of light consumption in Koohdasht cultivar (45. 2 gram per mega Joule) under Zinc sulfate + Iron chelate foliar application and its lowest value (08. 2 gram per mega Joule) was obtained in control plants. Spraying with nano chelate zinc + nano chelate of iron and Iron chelate + Zinc sulfate increased the grain yield of wheat cultivar Chamran by 44. 27 and 95. 15 percent, respectively, compared to control treatment. In Koohdasht cultivar, zinc and iron nano chelate had no significant effect on grain wheat agronomy in Koohdasht cultivar.
