The simulation models of yield response to water are expected to play an increasingly important role in the optimization of water productivity (WP) in agriculture. In this study, the CERES-Wheat model was used to simulate of wheat yield response under different irrigation-cultivar treatments with three irrigation treatments in main plots and Five wheat cultivars in sub plots consisted of C1:C-75-5, C2: C-78-4, C3:C-78-8, C4: C-79-6 and C5: C-79-16 in Mashhad region during the years of 2002-2003 and 2003-2004. According to the results, the relative root mean square error of grain yield simulation by CERES-Wheat model was 7 and 10 % for 2002-2003 and 2003-2004 years, respectively. Because, the relative root mean square error was less than 10 percent, so done well simulation. Also, the root mean square error calculated for grain yield for both years was less than 10 percent of the observed mean. The results are indicating a good match to the simulation results of the model. The value water productivity based on crop evapotranspiration and irrigation water value in I3-C-79-6 treatment has the value highest for both years of 2002-2003 and 2003-2004. Therefore, the noted irrigation management (I3) and wheat cultivar (C-79-6) can be recommended in the study area. The overall findings of this study to confirm the optimal performance of the model CERES-Wheat in the growth process simulation and the water impact on yield in the study area. Manuscript profile

Lead (Pb) is an environmental pollutants and cause of serious effects on human health due to the properties of accumulation, toxic and long-lasting. In this study, different water level management, including flood irrigation, control water level in 20 and 36 cm below the soil surface and intermittent irrigation in rice cultivation were studied on amount of available Pb in a soil and accumulation in shoot of rice plants. The experiment was performed under the completely randomized design and with three replications at Shahrekord University. The results showed that the effect of irrigation management on the amount of available Pb in soil and accumulation in shoot was significant (p<0.01). Moisture content in the root zone, have greater effect on uptake and translocation of this element in soil and plant parts. Use intermittent irrigation management (including flood irrigation and so stop, until decrease water table used by plant to 4cm under soil surface), water  table control in 20cm under soil surface (50% irrigation) and water  table control in 36cm under soil surface (10% irrigation) compared to flood irrigation, led to decrease 8.78%, 21.53% and 40.09% in the available Pb in soil respectively, and decrease 26.71%, 35.82% and 52.01% in the Pb uptake in the stems and leaves and 15.80%, 44.19% and 49.28% decrease in the Pb uptake in the seed respectively.

In order to determine the effect of different irrigation managements on rice growth indices, an experiment was done in factorial based on randomized complete block design in Rice Research Institute of Iran, Deputy of Mazandaran, Amol during 2011. Treatments were different irrigation managements including Alternate Wet and Drying (AWD), Semi-Dry Cultivation (SDC), combining Shallow water depth with Wetting and Drying (SWD) and Traditional Irrigation (TI) and two contrast cultivars of Tarom and Fajr as native and improved cultivars, respectively. Growth indices were fitted using measuring the dry weight and leaf area over seven sampling times during rice growing stages. The results showed that IT (with an average of 7694 kg) had the highest paddy yield followed by AWD (with an average of 7056 kg), SDC (with an average of 6856/8 kg) and SWD (with an average of 6358/7 kg). Leaf area index in Tarom cultivar varied from 2.99 in the combining Shallow water depth with wetting and drying to 4.6 in alternate wet and drying regimes. By contrast, LAI in Fajr cultivar ranged from 4.1 in the alternate wet and drying to 5.6 in traditional irrigation regimes. In conclusion, the maximum leaf area index, net assimilation rate in Tarom and Fajr cultivars to AWD and SDC irrigation managements could be introduced. Manuscript profile

Correct and convenient management of water resources by preserving the sources in regional and national scales is an inevitable need. Models are the best methods to select most efficient irrigation method lead to high yield response. In this simulation effects of water deficit irrigation in Bilasuvar plain on the north-east of Ardabil province has been simulated on wheat and corn crops using Budget soil and water balance model. By choosing the product, minimum and seasonal methods with different time steps and also setting the relative evapotranspiration or relative evaporation model has been calibrated for the observation year (2004-2014) and amount of yield was estimated. Result of the statistical analysis shows that choosing the product method with 10 day time periods provides the best simulation using relative evapotranspiration with amounts in an R^2 of 0.98, an RMSE of 78% and an EF of 0.83 that between observed and simulated data of wheat and amount in an R^2 of 0.87, an RMSE of 7.4% and an EF of 0.83 of corn. Later water consumption graphs, performance for each statistic period (2004-2014) under different irrigation strategies have been drawn for both crops. Results demonstrates significant impact of rainfall amount, water preservation capacity, water consumption management and water tension in both crops during the middle stage of its growth compared to the stages of growth including first and final stage. This important fact must be considered for planning the water deficit irrigation schedule. Manuscript profile

In order to evaluate the effect of plant growth promoting bacteria (PGPR) on some physiological traits of Black cumin under Water Deficit Stress, a split-plot experiment based on randomized complete block design with three replications was conducted at the research farm of Shahrekord University in 2015- 16. Factors were irrigation in three levels (100, 75 and 50 % of water requirement) and bacteria in seven levels (control, Bacillus sp. Strain A, Bacillus amyloliquefaciens, Bacillus sp. Strain B, Azotobacter chroococcum, Pseudomonas putida and Azopirillum lipoferum). Results showed a significant effect of water deficit, PGPRs and their interaction on all traits. It was demonstrated that in 50% of water requirement treatment reduced total chlorophyll, RWC and grain yield by 28%, 14.4% and 28.4%, respectively. Within each three irrigation levels, the bacterial treatments had the maximum amount of measured traits than control treatment. So that all PGPRs under 50% water requirement treatment could increase chlorophyll b, RWC and grain yield as compared to control. Also, B. amilolykofosins and strainB application under 75% water requirement treatment had the highest grain yield. Overall, this increase was more significant in B .amilolycophysin, Bacillus strain A, strainB and Azopirillum lipoferum treatments. according to the this study results, inoculation of Black cumin seeds with PGPRs is recommended to increase physiological traits and crops yield and alleviation of adverse effects of water stress.

In order to investigate irrigation management and the effects of different amounts of nitrogen fertilizer on hybrid corn SC704 experimental in the form of crushed plots in the form of complete randomized block design in three replications during two crop years 2015 and 2016 in Golestan province, in Katul was done. The main factor of irrigation cycle by day in four levels including 7, 14, 21 and 28 days and the secondary factor of nitrogen fertilizer in four levels included 60, 120, 180 and 240 kg.ha-1. The results of analysis of variance showed a significant effect between irrigation cycle and nitrogen on Weigh of 1000 grains, grain yield, seed nitrogen and biomass yield. The results showed that 28 days of irrigation reduced grain yield, seed nitrogen, seed phosphate and seed potassium compared to 7 to 14 days of irrigation. The increase in nitrogen fertilizer to 180 and 240 kg.ha-1 increased the yield of the grain by affecting the biological yield and yield components seed nitrogen, seed phosphate and seed potassium. However, nitrogen consumption in higher amounts under stress conditions (21 to 28 day Interval Irrigation) not only did not have a positive effect on yield, but also reduced grain yield by 180 to 240 kg.ha-1. The highest grain yield was obtained in the combination of 7 and 14 day irrigation treatment and nitrogen level of 240 to 180 kg.ha-1 and 12209, 11416, 10147 kg.ha-1. The results of the average comparison between the two years showed that the highest number of grains per corn was 583, the Number of grains per row as 40.3 and the Weigh of 1000 grains was 138.9 grams and seed nitrogen 3.991 µg.g-1 DW in the second year.
