Utilization of Rice Hull as a New Substrate for Turf Grass Seed Germination in Sod Production as a Sustainable Approach
Sod culture is one of the important methods in establishing and repairing of turf grass, especially in sport fields. Nowadays, a mixture of sand and peat are commonly used in sod production in Iran. Because peat media is expensive, it seems necessary to find an alternative medium. Rice hull, tea waste and leaf compost as economical organic material that are available in huge loads in north of I...
متن کاملA new approach to the polygons rasterization in GRASS
Within the GIS framework the rasterization of polygons vectorial themes is needed when a raster approach has to be applied in the theme analysis: for instance in the overlay between some normative zones (i. e. a polygon vectorial theme) and one or more environmental phenomena (typically represented by a raster model). It is well known that, formally, an univocal algorithm doesn’t exist; the mos...
متن کاملPhysiological and Antioxidative Responses of a Halophytic Grass Leptochloa fusca L. Kunth (Kallar grass) to Salinity
The effects of salt stress on growth and some physiological parameters of halophytic plant, Leptochloa fusca L. Kunth, were investigated. The seedlings were irrigated with half-strength Hoagland solution and then treated with different concentrations of NaCl (0, 100, 300, 500 and 700 mM) for 15 days. The fresh and dry weights of both root and shoot were unchanged at 100 mM NaCl and decreased at...

گیاه مرتعیKunth.Melica persica گونه‌ای پایا از خانواده گرامینه (Poaceae) با دامنه سازگاری نسبتاً وسیع است که آنرا بهعنوان یکی ازگیاهان مهم مرتعی به‌ویژه در امر حفاظت خاک مطرح می‌سازد. این گیاه بومی ایران است و عمدتاً در دو منطقه رویشی ایران- تورانی و خزری رویش دارد. برای مطالعه آت‌اکولوژی این گونه ابتدا رویشگاههای آن در منطقه خراسان (شامل سه استان خراسان فعلی) شناسایی گردید و خصوصیات رویشگاهی (ا...
متن کاملKikuyu Grass: A Valuable Salt-Tolerant Fodder Grass
The turf grass Pennisetum clandestinum Hochst. (kikuyu grass) is one of the candidate plants for utilization and reclamation of salinized areas. The capability of kikuyu grass to grow under saline conditions was tested during 6 months, under various irrigation treatments (tap water control, 80-mM, 150-mM, 200-mM, 240mM NaCl). Plant biomass production was visibly affected only at NaCl concentrat...
