A split-plot factorial experiment using the randomized complete block design was conducted on physiological characteristics of forage millet cultivars in Damghan in the cropping year 2012-2013 to study the effects of Nitroxin fertilizer under irrigation cessation conditions (based on BBCH, or the phenological stages of plants). The treatments included three levels of irrigation (control with complete irrigation, irrigation cessation at the start of the flowering phase, and irrigation cessation at the completion of the flowering phase) in the main plots, and Nitroxin application (+) and no Nitroxin application (control) and forage millet cultivars (Bastan, Pishahang, and Isfahan) in the subplots. Results showed the maximum protein contents belonged to the Isfahan and Pishahang cultivars with 24.31 and 24.10%, respectively, and the largest fiber contents to the control treatment and to the Bastan cultivar at 88.43 t/ha. The maximum dry weight of aerial parts under the triple interaction effect of fertilizer * cultivar *irrigation was 15.27 g/m2, and the maximum plant height under the mutual effects of cultivar * Nitroxin fertilizer 148.27 cm. The very rapid growth of millet, its short growing season and drought tolerance, its uniqueness with regard to harvest time, and its positive response to Nitroxin application can help to expand millet cultivation in the arid and semi-arid regions of Iran Manuscript profile

Experimental crop year from 2010-2011 as a split plot in a randomized complete block design with three replications at the Agricultural Research Station, salesperson biokola (Neka) was performed. The main factor for irrigation interval is in four levels of I1, I2, I3 and I4 (75, 100, 125 and 150mm grouped evaporation from pan evaporation respectively) and nitrogen sub factors are which equal to zero, 200 and 400 urea kg in hectar. Results show that more wet forage performance reached in hectar with 125mm evaporation from pan evaporation in irrigation interval 71230 in hectar, but the most wet forage performance in hectar in gain with 75 and 125mm evaporation from pan evaporation respectively which is equal 19030 and 17810 kg in hectar. Maximum profitability of dry material water usage reached with 125mm irrigation interval in evaporation from evaporation pan is equal to 15.37 kg on mg. Most performance of wet forage reached in wet forage performance according to irrigation + raining under the care of interaction effects in irrigation interval × nitrogen fertilizer for cares with 125mm irrigation interval and 150mm evaporation from evaporation pan with and 184 kg nitrogen usage in hectar which is equal 79200, 13000 kg in hectar and 67.34 and 12.44 percent.

Appropriate management of planting dates for each cultivar is necessary for enhancing site productivity in forage sorghum plantation. To investigate the effects of planting dates on yield components and protein percentage of sorghum cultivars, an experiment was conducted at Research Farm of Isfahan University of Technology, Lavark in 2013. A split plot design in the layout randomized complete block design with three replications was used. The main plots were concluded 15th June and 30th June, and subplots were 4 cultivars, namely, Sarasai, Speedfeed, Pegah and Sofera. Planting date had significant effect on plant height, LAI, total fresh yield and stem dry yield. The effects of cultivar significant on plant height, LAI, stem fresh yield, leaf fresh yield, total fresh yield, stem dry yield and total dry yield. Protein percentage was not influenced by both planting date and cultivar, and there was no trend in this treatment. Stem fresh yield, leaf fresh yield, total fresh yield, stem dry yield, leaf dry yield and total dry yield was significantly influenced by planting date and cultivar. On the basis of the results, it seems that cultivation of Speedfeed because of its high fresh and dry forage production in 30th June is suitable. The forage and protein percentage of three other cultivars are the same and there were no differences between them. Manuscript profile

In order to study Effect of Cadmium on Ditirozin (D-T) Biochemical biomarker and Catalas (CAT) Antioxidant Enzyme in some Crop species the some Crop species, an experiment was conducted in experimental Greenhouse of  Islamic Azad University of Karaj branch in 2009-2010 year. The studies were carried out in a Factorial experiment based on a randomized complete block design with three replactions. The factors were Cd doses into soil at three levels 0, 40 and 80 (mg Cd/kg.dw soil) and Crop species at three levels, annual Alfalfa (Medicago rigidula), Hairy vetch (Vicia villosa ) and Canola (Barassica napus). Results showed that different Crop species and Cd doses into soil had highly significant effect on all of Experiment characteristics. Highest amount of Ditirozin (D-T) Biochemical Biomarker related to Canola (with 10.99 µMol/g.Fw) and lowest of this trait related to Hairy vetch (with 8.86 µMol/g.Fw). Highest amount of Catalase (CAT) Antioxidant Enzyme related to Alfalfa (with 55.79 U/mg.protein) and lowest of this trait related to Hairy vetch(with 52.77 U/mg.protein). With increase Cd Doses into soil, Ditirozin (D-T) Biomarker content was increased, but Catalas Antioxidant Enzyme was decreased. 80 (mg Cd/kg.dw Soil) doses with 11.72 (µMol/g.Fw) and 0 (mg Cd/kg.dw Soil) doses with 6.52 (µMol/g.Fw)  were highest and lowest Ditirozin (D-T) Content, respectively. 0 and 80 (mg Cd/kg.dw Soil) doses with 63.30 (U/mg.protein) and 49.39 (U/mg.protein) were highest and lowest Catalas (CAT) Antioxidant Enzyme Content, respectively.

       In order to study effect of lambsquarters (Chenopodium album) interference on some traits of marigold (Calendula officinalis) and weed seed production index a factorial experiment was conducted during 2012 in Islamic Azad University, Tabriz Branch, based on randomized complete blocks design in 3 replications. Studied factors were weed densities of 0, 2, 4, 6 and 8 plants per meter row and its relative emergence times of simultaneously, 10, 20 and 30 days after crop. Results indicated that emergence of 4 weed plants per meter row had no significant effect on crop growth period. With increasing of weed density more than 4 plants per meter row leaf chlorophyle content index decreased fron 17.5 to 13.5 (17.5% reduction). Weed interference caused to earlier appearance of leaf senescence symptoms from 9 to 13 days. Effect of higher weed densities on plant height was more than lower densities. Lambsquarters had greater negative effect on marigold yield, and weed density was more effective than its emergence time. Harvest index in weedy plots reduced fron 32% to 25%. Essence yield in marigold decreased 14.4 mL m-2 per weed density. In weed plants emerged simultaneously, 10, 20 and 30 days after crop, 5.6%, 4.4%, 4.1% and 4% of above ground biomass allocated to seed, respectively. It is recommended for the weed controling in marigold field, when emerged atleast 2 plants per meter crop row simultaneously or 10 days after crop. Manuscript profile

To investigate the effect of ascorbate and gibberellin on some physiological characteristics of the Salvia medicinal plant under salt stress conditions, an experiment was done at municipal greenhouse No 15 in March 2013. The experiment was as factorial based on completly randomized  designe (CRD) with four replications. Experimental factors including salinity levels in 4 levels (0, 25, 50 and 75 mM Nacl), ascorbate in 2 levels (0 and 4 mM) and gibberellin in two levels (0 and 2 mM). The mean comparison  showed that the main effect of salinity showed that the cause  of the decline of activity of antioxidant enzymes and increase the amount of soluble sugars and proline. . Except of the three double interaction effect of factors on proline and soluble sugars in other cases, there was significant difference on other traits. As well, instead of triple interaction of treatments on, proline, catalase and ascorbate peroxidase in other cases no significant difference was observed. In this case the maximum amount of  proline production (12/67 mg/g fw), catalase activity (19/68 mg/protein. min) and ascorbate peroxidase (61/25 mg/protein. min) conducted in 75 mM Nacl and ascorbate and gibberellin application.As a result of the application of ascorbate as a strong antioxidant and GA as growth regulators, foliar damage due to stress, these two compounds were offset and in the absence of ascorbate and GA was given to the plant, the activity of antioxidant enzymes decreased.   Manuscript profile
