        In order to investigate the chemical control method of weed potato (Solanum tuberosum) weeds based on a reduced dose of rim sulfurone and sulfosulfuron, a randomized complete block design with four replications and 15 herbicide treatments including Titus, Apyrus and Boxer, Titus 25%, 50% And 75% of the tested dose, Apyrus 25%, 50% and 75% of the tested dose, Boxer with 25%, 50% and 75% of the dose of Titus, Boxer with a 25%, 50% and 75% of the dose of Apyrus, Control without weed and Control in the presence of weed The 25 May 2016 was carried out in Pars water and soil lands located on Mashkin-e-Dashte road of Karaj. The investigated factors included dry weight percentage of weeds by species and herbicide efficiency during 30 and 45 days after spraying and at the harvesting stage, the number of small and large tubers, the weight of the small and large tubers, the diameter of the small and large tubers, and Potato tuber function was measured. Among the investigated treatments, the highest impact factor (herbicide efficiency) was related to Boxer treatment with 75% of the Apyrus dose. The lowest herbicide efficacy was related to treatment with 25% Titus dose (15.75%); also, treatment with 75% of the Apyrus dose reduced the weight of 64% Dry broadleaf weeds and 62% dry weeds were leafy weeds and had a good yield of Baxer 3 Lit/ha with a coefficient of effect of 64.2% compared to non-weeding control.

        To increase the competitive ability of wheat with weeds by the interaction effect of essential, extract allelopathic (Artemisia sieberi) and nano an experiment was conducted in Alborz, Karaj in 2016 as a factorial experiment in randomized complete block design with three replications. experimental treatments including Artemisia essential, extract allelopathy in six levels: essential of 0.6, 0.4 and 0.2 ml/m2, and extracts 0.6, 0.4 and 0.2 ml/m2, control with weed (non-use of allelopathic compounds), weed control (weeding) and Nano ZFMB (Zinc, Iron, Manganese & Boron) Nano at three levels: Nano, one Lit.haˉ¹, two Lit.haˉ¹of, a control (no use of Nano).The results of this study showed that essential oil treatment of 0.6 ml/m2 with consumption of two Lit.haˉ¹ Nano reduced 73.33% of total dry weight of weeds compared to the control of presence of weed. As a result, conditions for proper plant growth were provided. Nano effects have a more positive effect on wheat growth and the plant maintains the balance in the production of grains and straw by producing an adequate shoot. Also, in reducing the competition of weeds on wheat, the allocation of photosynthetic photos to the seed was more than straw. This increased 55.83% of wheat yield compared to the control of presence of weed. Manuscript profile
