[ 1 ] - Studying the effects of mycorrhiza and vermicompost fertilizers on the growth and physiological traits of Vetiver Grass (Chrysopogon zizanioides L.)
As an herbaceous, perennial, and evergreen plant, Vetiver Grass (Chrysopogon zizanioides L.) can be used for the improvement and development of arid and semi-arid rangelands. To assess the interaction effect of organic and biological fertilizers on the growth and physiological traits of Vetiver grass, the dry weight of shoots and roots, essential oils, chlorophyll, carotenoids, and proline...
[ 2 ] - Drought Monitoring Using Vegetation Indices and MODIS Data (Case Study: Isfahan Province, Iran)
Drought is a major problematic phenomenon mostly for semi-arid areas of Iran. During drought periods, reduction in vegetation levels causes such problems as soil erosion, surface runoff, flood risk, etc. Therefore, the assessment of drought effects on plant covers is the most important issue. This research was conducted in 2015 using the extracted vegetation indices from Moderate Resolution Ima...
[ 3 ] - Effects of Wind Erosion and Soil Salinization on Dust Storm Emission in Western Iran
Dust storms are known as hazardous problems in western part of Iran. Iraq is one of the main sources for dust storm arriving to the western part of Iran. The Radial Basis Function Network model (RBFN) has been used to assess wind erosion hazards in the source area of dust storms over several western Iranian cities. Normalized Difference Salinity Index (NDSI) was used to determine the changes in...
[ 4 ] - Prediction of Land Use Management Scenarios Impact on Water Erosion Risk in Kashidar Watershed, Azadshahr, Golestan Province
Soil erosion is a serious problem especially in northern parts of Iran. One themost important side effects on soil erosion may be the decline in qualities of soil refers toagricultural productivity. So it is very important to assess the soil erosion risk for thesustainable development of agriculture. This study outlines ways undertaken to provide anew tool to manage water erosion from physical ...
[ 5 ] - Estimation of Nutritive Values of Some Range Species as Indicators for Rangelands Management
Information on different rangeland plants’ nutritive values during variousphonological stages is of importance for the rangelands management. This information helpsrangeland managers to choose proper grazing times to achieve higher animal performancewith no detrimental effects on the rangeland vegetations. Effects of various plant parts’phenological stages and vegetation types on reserve carboh...
[ 6 ] - کاهش اثر گرد و خاک بر خصوصیات کمی و کیفی انگور رقم بی‌دانه سفید در اثر شتشو با دی‌اکتیل
به‌منظور ارزیابی اثر گرد و خاک بر انگور رقم بی‌دانه سفید، آزمایشی به‌صورت بلوک‌های کامل تصادفی در ایستگاه تحقیقات انگور ملایر در سال 1394-1393 انجام شد. تیمارهای آزمایش شامل تیمار گرد و خاک به صورت مصنوعی، تیمار راهکار (شتشو با محلول آب و ماده دی‌اکتیل) و شاهد بودند. در این پژوهش، کلروفیل a و b، کاروتنوئید، صفات رویشی از قبیل طول شاخه، طول دمبرگ، طول برگ، سطح برگ، فاصله میان‌گره و صفات زایشی...
[ 7 ] - Dust Storms Detection and Its Impacts on the Growth and Reproductive Traits of Grape vine (Vitis vinifera) in Malayer Plain
Introduction: Dust storm is one of the air pollutants in desert areas that have damaging effects on environmental ecosystems. This phenomenon usually happens when severe winds occur in arid areas which are accompanied by the ascent of dust particles to the upper layers of the atmosphere. HYSPLIT model can assist in detecting the path of dust entering the stations. In addition, synoptic patterns...
