Abstract:

Two field experiments were laid out in order to study on effects of delaying cropping system on growth and yield components of different wheat cultivar in Iran in two years 2011 and 2012. The trial was laid out in RCBD with split plot arrangement having three replications at Dorud, Lorestan province, Iran. Five sowing dates i.e. October 31, November 15 and 30, December 15 and 30 were in main plots, whereas five wheat cultivars (Pishgam, Parsi, Bahar, Sivand and Pishtaz) were in sub plots. Results shows that the effect of year, sowing date and cultivar were significant on all parameters. Maximum number of grain per spike and HI related to 31-Oct and Sivand cultivar treatments. Sivand cultivar has the highest seed yield in two years and the Parsi cultivar has the lowest seed yield. The highest seed yield for sowing date gave at 31-Oct sowing date and the lowest seed yield gave at 30-Dec sowing date. In final results of present study showed that for achieve to highest seed yield must be sowing Sivand cultivar in 31-Oct sowing date.
