Study and Comparison of Figures Wheat yield on deficit Irrigation

With due attention to continuous drought and limitation of water source in Bushehr province, should use water maximum with methods of deficit irrigation, without decrease yield. So "study and comparison of Wheat figures yield on deficit Irrigation"to do in 2007-2008 years on the Agriculture Research Center of Borazjan. The design of thesis is the split of plots in blocks. Irrigation factor is in main plot and three level (full irrigation, deficit irrigation and complementary irrigation) and figures factor in sub plot, and four figures (Nicknejad, Chamran, Koohdasht and Zagros). Full irrigation is selected with period 6days, deficit irrigation with period 10 days, and complementary irrigation with 3 irrigations (first irrigation, secondary irrigation and irrigation in time of spike). This search does in 3repeat. Results of analysis variance show with increase drought in two treatments (deficit irrigation and complementary irrigation) in all figures decrease these items, yield, weight of 1000 seeds, seeds number in spike, weight dry, Harvest index, length of stem, etc). Maximum average of more quality and yield is in full irrigation treatment and least average is in complementary irrigation. Two figures Koohdasht and Zagros have good particulars, example resistance to drought and hot, resistance to pouring and etc. in more quality and yield, show maximum average, and two figures chamran, Nicknejad which old and weak particulars have least average.
