Abstract:   (48 Views)
In order to investigate the effect of iron and zinc chemical fertilizer and nano-Chelate foliar on on chlorophyll concentration, radiation use efficiency and grain yield of two bread wheat cultivars, an experiment was carried out as a factorial based on a randomized complete block design with three replications at the Zarinabad Agricultural Research Center, Ilam, during in 2016-2017. The factors consisted of spraying in seven levels (control, spraying with iron chelate, iron nano chelate, zinc sulfate, zinc nano chelate, iron chelate + zinc sulfate and iron nano chelate + zinc nano chelate) and the second factor of two wheat cultivars (Chamran and Koohdasht) was. The results showed that spraying with iron fertilizers and zinc sulfate had a significant effect on chlorophyll concentration and maximum leaf area index at 1% and 5% probability levels, respectively. The maximum leaf area index at the level of 1% in Koohdasht cultivar was 7.21% higher than Chamran cultivar. Spraying with nano-chelates of iron with nano chelate has reached the maximum dry matter accumulation (782 g.m-2). The least trait was obtained at 681 g.m-2 in control plants (non-spraying). In Chamran cultivar, the maximum amount of radiation use efficiency was 2.30 g.MJ with the use of iron nano chelate, which was 10.27% more than control plant. The highest amount of light consumption in Koohdasht cultivar (2.45 g.MJ) under zinc sulfate + iron chelate and its lowest value (2.8 g.MJ) was obtained in control plants. Spraying with nano chelate on zinc + nano chelate of iron and iron chelate + zinc sulfate increased the grain yield of wheat cultivar Chamran by 27.44 and 15.95 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.
Keywords: Zinc sulfate, Iron chelate, Chlorophyll and Nano-fertilizer.
