  In order to evaluate the effect of reducing the use of herbicides to control wild mustard in canola varieties were different densities in the province of Alborz as split - factorial randomized complete block design with three replications and treatments include: Rapeseed (C) as the main factor (MP) on 2 level (including: (C1) Zarfam and (C2) option 500), and wild mustard density (D) in three levels (including (D1) zero, (D2) 7 and (D3) 15 plants per square meter) and herbicides. (H) in three levels (including (H1) 100%, (H2) 75% and (H3) 50% recommended dose) are as minor as a factorial was. The dry weight of weed species, rapeseed yield components, and seed yield and growth parameters were analyzed. Based on the results, the highest percentage of dry matter loss than control weed (weed), respectively C₁D₂H₂ treatments and C₂D₂H₁ and C₁D₂H₁ with 19/78, 12/78 and 0/78%, the highest percentage of dry matter loss had the lowest percentage of weeds and weed dry matter loss (18/48) of treatment was C₂D₃H₃. By comparison, average grain yield, in the presence and absence of wild mustard showed that the highest grain yield and the lowest in Option 500 is Zarfam. Manuscript profile

  2 - The impact of biological and chemical fertilizers to use salicylic acid on morphological characteristics and yield of corn
  
  In order to examine the effects of biological and chemical fertilizers with the use of salicylic acid on the agronomic characteristics of corn as a factorial experiment in randomized complete block design with three replications at the Agricultural Research Station in 2 More

  In order to examine the effects of biological and chemical fertilizers with the use of salicylic acid on the agronomic characteristics of corn as a factorial experiment in randomized complete block design with three replications at the Agricultural Research Station in 2011 was Boroujerd. Factors examined included three levels of phosphorus fertilizer (0, 100 and 150 kg ha), two levels of biological fertilizer (mycorrhizal fungi) (seed inoculation and seed inoculation) and two levels of salicylic acid (0/5 and 1 mM), respectively. The results showed that phosphorus fertilizer and mycorrhizal significant effect on plant height, stem diameter, ear length, ear diameter, grain yield and biological yield, respectively, with the application of 150 kg P ha grain yield of 9006 kg was found that 48% More the treatment of non-usage. In the case of seed inoculation with mycorrhiza on the amount of 8412 kg per hectare, respectively, which was 24% higher than the treatment of non-inoculated seeds. Salicylic acid has a significant effect on plant height, stem diameter, ear length, ear diameter, grain yield and biological yield and harvest index. The application of 1 mM salicylic acid yield of 8316 kg per hectare, respectively, which was 24% higher than the treatment of non-use. Phosphorus and mycorrhiza interaction on grain yield and biological yield was significant. Salicylic acid and phosphorus interaction and effect on yield only three treatments was significant Manuscript profile

  In order to evaluate the effects of four commercial formulations of sulfonylurea herbicides include Titus (rim Sulfurun), Cruz (nicosulfuron), Ekoup (Foramsulfuron) and Aultyma (nicosulfuron + rim Sulfurun) and four new herbicide dose Lomax (Mzutryun + S Mtalaklr + Trbu More

  In order to evaluate the effects of four commercial formulations of sulfonylurea herbicides include Titus (rim Sulfurun), Cruz (nicosulfuron), Ekoup (Foramsulfuron) and Aultyma (nicosulfuron + rim Sulfurun) and four new herbicide dose Lomax (Mzutryun + S Mtalaklr + Trbutylazyn) in the form of pre- and post-emergence and D + MCPA (U-46 Dyfluyyd) and treatment without herbicide application in the field after corn on the performance and growth parameters of wheat were studied. Experiments in Tehran (Karaj) in a randomized complete block design was done after harvest. Wheat (the leading) in the previous field of corn that were treated with these herbicides. In this experiment, grain and biological yield, harvest index and crop growth parameters in rotation with maize had been analyzed. Based on the results, when the crop was wheat in rotation with maize, herbicide residues Titus and post-emergence herbicide for Lomax (5.4 liters per hectare) wheat grain yield and 7/19 respectively. and 1.9% respectively 3.9 and 1.7 percentage yield decreased, and had the most negative effect on wheat. Lomax also treated postemergence at a rate of 4 liters per hectare, with a maximum leaf area index, dry matter production had the highest and lowest herbicide treatments produced Titus leaf area index, the lowest dry matter, respectively.
