  Mulches bring several benefits to lettuce cultivation.A study on the lettuce ‘Red Rapids’ has been conducted to determine the influence of the different colored plastic mulch on its growth. The experiment consisted of five color treatments as follows; treatment 1- metallic silver (control), treatment 2- red, treatment 3- orange, treatment 4- yellow and treatment 5-green. Results showed that the colored mulch treatments had significant influenced on the different parameters including: root length at harvest, average leaf length, leaf diameter, plant height, plant weight, number of leaves at harvest and percentage survival. Lettuce grown in red mulch had significantly outperformed the other colored treatments. Manuscript profile

  به‌ منظور بررسی اثر خاکپوشه پلاستیک و مواد ضد تعرق کائولین و آترازین تحت تاثیر سطوح مختلف آبیاری بر برخی صفات فیزیولوژیک و عملکرد دانه ذرت رنگین، آزمایشی مزرعه‌ای در منطقه برازجان، استان بوشهر در دو سال 1396-1395 اجرا گردید. آزمایش به‌صورت اسپلیت اسپلیت پلات بر پایه طرح بلوک‌های کامل تصادفی با سه تکرار اجرا شد. عامل اصلی آزمایش شامل آبیاری در سه سطح، شامل: 1) 25 درصد تخلیه رطوبتی آب قابل استفاده خاک؛ 2) 40 درصد تخلیه رطوبتی آب قابل استفاده خاک و 3) 60 درصد تخلیه رطوبتی آب قابل استفاده خاک و عامل‌ فرعی در دو سطح شامل خاکپوشه پلاستیک و بدون خاکپوشه و عامل‌ فرعی فرعی در سه سطح شامل مواد ضد تعرق کائولین، آترازین و شاهد بدون مصرف ماده ضد تعرق بودند. نتایج نشان داد که برهمکنش سطوح مختلف آبیاری، مواد ضد تعرق بر نسبت Fv/Fm و برهمکنش خاکپوشه پلاستیک و مواد ضد تعرق بر میزان قند محلول برگ معنی‌دار گردید. در سطح آبیاری 60 درصد تخلیه مجاز رطوبتی، بیشترین نسبت Fv/Fm (578/0) در تیمار آترازین و کمترین مقدار آن (468/0) در تیمار کائولین بدست آمد. در شرایطی که میزان رطوبت خاک محدود است، استفاده از خاکپوشه پلاستیک و آترازین جهت حصول حداکثر عملکرد کیفی و کمی قابل توصیه می‌باشد.

  The experiment was performed in order to comparison of ecological and chemical management methods on the emergence, growth and development of the potato weeds in 2015 on the two locations of Agricultural Research Stations Alarogh and Samian in Ardabil province in a randomized complete block design with three replications. The treatments were included. 1.) Between rows of potatoes sprayed with Trifluralin herbicide. 2.) Between rows of potatoes sprayed with Metribuzin herbicide. 3.) Cultivation practice. 4.) Usage of plant mulch contains the wheat stubble. 5.) Usage of plant mulch contains the canola stubble. 6.) Usage of black polyethylene sheets mulch. 7.) Usage of transparent polyethylene sheets mulch. 8.) Weed infested (interference) treatment. 9.) Weed free (control) treatment. Based on the results obtained in present study, mulch, herbicide and cultivator had significant effects on potato weeds density in both locations so that the least density of weed obtained in wheat stubble mulch and then usage of Metribuzin herbicide treatments, respectively. Most weed density was counted in the weed interference treatment equal to 99.1 plants per square meter. The usage of wheat mulch compared to the non-application, reduced to 84 percent of weed density compared to weed interference treatment in potato crop. The application of canola stubble residues compared to weed interference treatment reduced the weed density as 79 percent. The broad leaf species of Common Amaranth, Bindweed and Common lambsquarters density, as important potato weeds in all herbicide treatments, mulch and cultivation, decreased compared to weed interference treatment...

  In order to evaluate effect of mulch and bed formation on yield quantity of corn and compete between weeds an experiment were conducted in 2011-2012 in field research of Islamic Azad University, Varamin branch. Experiment were in form of split plot based on complete block design with three replications. Bed cultivation in three level (flat, top and furrow) in main plot, mulch in three level (white plastic on dark, no mulch and control weed, no mulch with weed) in sub plot. The results showed that up to 8-leaf stage, the maximum leaf area, plant height, stem diameter at the soil surface and dry weight was observed in the context of Faro. White on black plastic mulch for all forms of bed control weed up to 99%. Mulch leads to grow corns faster than the ground without mulch and  mulch interaction was significant in the context of maximum yield in the mulch bed treatment bed (1103.61kg ha-1) were obtained. Results showed that bed form had significant effect on Harvest Index, grain yield, seed in ear, seed in row, row number. Mulch had significant effect on total biomass, harvest index, grain yield, seed in ear, seed in row, row number. Highest amount of seed in ear, row in ear for flat bed and highest thousand seed weight and row in ear for top bed. Increasing seed in ear, seed in row and row number by using mulch and therefore seed number increased.   Manuscript profile

  Identifying the critical time and timing of plant irrigation based on a precise and basic plan is the key to water conservation, improvement of irrigation operations and plant tolerance to water shortage in agriculture. In recent years, vesicular arbuscular mycorrhizal fungi have been used in many plants to deal with dehydration and drought stress. In this regard, an experiment was conducted as split-plot in the form of randomized complete block design with 3 replications in the Yasuj region at years 2015 and 2016. Water stress was considered as the main factor in the form of irrigation after 30, 60, 90, 120 and 150 mm of evaporation from the evaporation pan class A and mycorrhizal fungus was considered as a secondary factor in the form of no application, application of Glomus mosseae and application of Glomus intraradices. The results showed that the interaction of irrigation and mycorrhizal fungi on flower phosphorus, flower yield, biological yield and water use efficiency of Borage was significant. In irrigation levels after 60, 90, 120 and 150 mm of water evaporation from the evaporation pan, the use of mycorrhizal fungi Glomus mosseae and Glomus intraradices compared to the absence of fungi respectively increased the yield of plant flowers (30.04% and 27.35 %), (90.2% and 90.98%), (93.21% and 94.1%) and (81.73% and 78.86%), also, at these levels of irrigation, biological yield and water use efficiency of Borage flower achieved a significant increase in the presence of mycorrhizal fungus, compared to the absence of mycorrhizal fungus application. Application of both strains of mycorrhizal fungus Glomus mosseae and Glomus intraradices in irrigation levels after 90, 120 and 150 mm of water evaporation from the evaporation pan compared to no application of mycorrhizal fungus, respectively, resulted in a significant increase in the harvest index of Borage flower (44.55% and 43.36%), (13.21% and 15.96%) and (5.6% and 5.41%) and flower phosphorus (44.69% and 20.45%), (150% and 125%) and ( 267.74% and 235.48%). Mycorrhizal fungus was able to moderate the negative effects of drought stress and increase the above-mentioned traits in those irrigation levels, and based on the results of this study, irrigation treatment after 90 mm of water evaporation from the evaporation pan + the use of Glomus mosseae mycorrhizal fungi is recommended.
