Abstract :

Wheat is one of the most crops and Wheat bread is the main component of Iranian nutrition patterns. A two field experiments (2013-2014) was conducted as a randomized complete block design with 3 replications at two locations (Ilam and Bushehr) to study quantitative and qualitative traits of bread wheat cultivar Kohdasht. Treatments were two levels of Cycocel (CCC) (0, 2.5 g/L), application of Zinc sulfate (Zn) at the three rates (0, 25 and 50 kg/ha) and Nitroxin, as bio-fertilizer, (seed inoculated and non-inoculated). Results showed that CCC application in both locations had significant effect on yield and its components. CCC spraying in compared to control treatment increased spike number per meter square, grain number per spike and grain yield by about 14.6, 19.6 and 28.5 percentages, respectively. The highest grain protein content (13.8%), wet Gluten (36.1%), Gliadin (53.6%) and Glutenin (31.8%) were obtained from plants treated with CCC spraying, at 50 kg/ha of zinc sulfate and Nitroxin-inoculated seeds treatment. CCC spraying at the concentration level of 2.5 g/L, application of 50 kg of Zn and inoculation of seeds with Nitroxin resulted to the highest grain yield (1710 kg/ha) and the highest amounts of lysine, Threonine and Methionine were obtained by about 510, 545 and 772 milligram per 100 gram of protein sample, respectively. Overall, it can be concluded that CCC at the concentration level of 2.5 g/L, 50 kg/ha of Zn and seed inoculation with Nitroxin might be effective in improvement of grain yield in wheat under dry land farming.
