This study aimed to investigate Tasyrlfksh used in canola on the growth and competitiveness of the plant with weed in 1388 in a randomized complete block design with four replications in Alborz Province (Hashtgerd) came into force. The treatments were: Lasso (alachlor), Butyzan Star (Mtaraklr + Queen Merak), Tryduks (Dymtaklr), Treflan (trifluralin), Gallant Super (Hallux Fup-R-methyl ester), Sonalan (Ethalfluralin), Treflan + Gallant Super, without control and weed control. In this experiment, characteristics such as percent dry weight of weed species, yield and yield performance were analyzed. The results showed that among herbicides, Butyzan Star (5/2 Lit / ha) had the highest percentage of weed dry weight loss (42/86) and herbicide Treflan (2 Lit / ha) had the lowest percentage of dry weight the weeds (55/65), which is why most (2307 Kg / ha) and lowest (1990 Kg / ha) grain yield was highly above mentioned treatments. In between treatments, the highest yield without weed control with 2409Kg / ha and the lowest yield weed control with 1862Kg / ha and accounted for. Manuscript profile

In order reaching to occurate water regime in the condition of minimum tillage and its effect on the yield and yield component physiological index of rice varieties, a experiment had carried out the Agronomey year of 2006-2007 in the research field of shavour station. The experiment had carried out in split-plot design some Randomized complete block with three Replication that contains three water regimes with one day or check, Two (I2) and three days (I3) Interaction for the main factor level and three rice Varieties: red Anborie (V1) and champa (V2) and LD183 (V3) or Danial as main factor level. Results of experiment show that in physiological indices humidity stress increases leaf area index (LAI), also LAI in ANBURI and CHAMPA varieties was more than LD183 variety.In interaction effects between varieties and  humidity stresses, combination of  following treatments increased LAI: anburi variety , humidity stress (,irrigating after 3 days), champa vaiety, humidity stress (irrigating afterdays), LD183 , (both kind of humidity stresses). Humidity stress by frequency of irrigating after 2 days makes highest Crop growth rate (CRG), but by increasing of time priority of humidity stress CGR decreased. Champa variety has highest CGR between all. In interaction effects between local varieties and  humidity stresses CGR decreases by increasing period of humidity stress. But in LD183 rising of humidity stress period, increased CGR.In general Humidity stress decreased relative growth rate (RGR) in all varieties. LD183 has highest RGR between all varieties. In interaction effects between varieties and  humidity stresses, local varieties  show highest RGR when they got irrigated after 3 days but in LD183 humidity stress decreased RGR because of enlarging of LAI  and increasing of CGR in period of stress condition. Net assimilation ratio (NAR) decreased at first step of humidity stress condition but in continue at last step of plant growth, NAR increased simultaneously by increasing of humidity stress. LD183 had highest NAR between all varieties. In interaction effects between varieties and  humidity stresses, local varieties show decreasing in NAR because of humidity stress.  But NAR increased in LD183 Varity in condition of irrigating after 2 days and also by enlarging of period of humidity stress NAR show falling. So the results indicate that 2 and 3 humidity stresses treatments can be used for rice irrigating.   Manuscript profile

AbstractIn order to study the effect of organic and biologic manures on essential oil and some growth characteristic of herb dill (Anethum graveolens L. ) a field experiment was done in the form of factorial in randomized complete block design (RCBD) in research field of Islamic Azad University, college of agriculture and natural resources branch of karaj, Mahdasht,Iran in 2012. The treatments were: A) humic acid with three levels (a1 = none use, a2 = spraying on leaves[3 lit/ha], a3= soluble giving pie plant [6 lit/ha] , B) plant growth-promoting rhizobacteria with two levels (b1= none use, b2= use, C) seaweed extract(c1 = none use, c2 = soluble in irrigation water 1/5 lit/ha).Results illustrated that organic and biologic manures have significant preference in many of studied traits in compared to control. Humic acid had significant effect on essential oil, leaf length and shoot diameter at 1% level of probability. Among the treatments, soluble giving of humic acid pie plant + use of plant growth promoting rhizobacteria and seaweed had the maximum amount of essential oil and leaf length. Consumption of Plant growth promoting rhizobacteria causes increase in pedicel length and leaf length and decrease in MDA content. Maximum amount of pedicel length and root diameter was observed in Consumption of Plant growth promoting rhizobacteria and seaweed and none use of humic acid had treatment. Seaweed extract had significant effect on leaf length and shoot diameter at 1% level of probability. Experimental treatment had no significant effect on root length. Leaf spraying of humic acid and use of Plant growth promoting rhizobacteria and seaweed extract had maximum and minimum amount of root length and MDA content respectively. Overall, results showed that humic acid, plant growth promoting rhizobacteria and seaweed extract had additive effects on studied traits. Manuscript profile

In order to evaluate how chemical control of weeds growing Yi and after the mechanical stage in the city Khodabande potato experiment in a randomized complete block design with four replications and treatments were: 1. Snkur (recommended dose), 2. Titus (dose recommended), 3. Epirus (recommended dose), 4 Snkur + Titus (25% of the recommended dose), 5 Snkur + Titus (50% of the recommended dose), 6 Snkur + Titus (75% of the recommended dose ), 7. Snkur + Epirus (25% of the recommended dose), 8 Snkvr + Epirus (50% of the recommended dose), 9 Snkur + Epirus (75% of the recommended dose), 10. Titus (25% of the recommended dose ), 11. Titus (50% of the recommended dose), 12. Titus (75% of the recommended dose), 13 Epirus (25% of the recommended dose), 14 Epirus (50% of the recommended dose), 15 Epirus ( 75% of the recommended dose), 16 weed control, weed control factors were studied 17 weed species, potato plant height, number of leaves on the plant, total dry weight of air split, underground dry weight step 30 days after the second spraying poison (after the mechanical plant), and harvest: tuber yield, total biomass plant, tuber number per plant, tuber weight were measured. Based on the results, treatment Titus (recommended dose) in terms of bindweed and amaranth in the highest group were statistically numerically, although it has a dry weight of less than weed density was reduced doses according to the comparison showed that the average yield of herbicide Epirus recommended dose (57/27 tons per hectare) no significant difference in weed control though numerically less than it was, among herbicide treatments reduced dose of Snkur + Epirus (75% of the recommended dose), Snkur + Epirus (50% dose recommended) and Snkur + Titus (50% of the recommended dose) produced, respectively, 52/24, 35/24 and 10/24 tons per hectare in the same statistical that would have been acceptable performance and herbicide Titus 75% of the recommended dose produced a numerically 60/15 tons per hectare is the lowest yield.
