Abstract

To study the effects of different PLANTING DATEs and plant density on morphological traits of two wheat lines an experiment was performed at Moghan Agricultural Research Center in 2008. The experiment was done in split-split plot design. Four PLANTING DATEs (November 6‚ November 21‚ December 6 and December 21) were assigned to plot‚ two wheat varieties to sub plot and four SEED DENSITY (300‚ 350‚400 and 450 grain per square meter) to sub subplot with three replications. The results showed that the November 6th planting with 7397 kg/h was one of the best planting times based on grain yield. There was significant difference among wheat varieties based on harvest index‚ number of spikelet‚ plat height and panicle length with the probability of %1‚and with regard to the number of grain in a panicle this difference was around %5. Regarding those features there were not significant differences between Arta and Moghan-3. Different Grain densities for grain yield‚ panicle length and number of grain in the panicle in the %5 probability were significant. SEED DENSITY of 350 per square meter was 7170 kg/m‚ panicle of 9.08 and 42.43 grain in a panicle. Also‚ the effect of planting time on grain yield‚ harvest index‚ number of tillers‚ and peduncle length was significant. The correlation of variety and density on grain yield was meaning full‚ too. Third PLANTING DATE‚ and second density had the best results in grain yield. Although variety was not of significant for grain yield‚ Moghan-3 had more grain yield compared to Arta. For Moghan-3 variety third planting time and for Arta the first planting time seems the best. We also made the correlation between variety density significant so that Moghan-3 variety in second density and Arta variety in third density produced the most grain yield. Finally‚ based on these experiment results it is recommended to plant Moghan-3 with 350 SEED DENSITY in a square meter in the first half of November and Arta with 400 SEED DENSITY in the second half of November. In this study the correlation between grain yield and fertile tiller was found to be positive but non-significant‚ with the number of spike lets negative and non-significant. So it is useful to use ideal fertile tiller varieties when we want to choose suitable planting varieties.
