Diversity of species and order of arrival can have strong effects on ecosystem functioning and community composition, but these two have rarely been explicitly combined in experimental setups. We measured the effects of both species diversity and order of arrival on ecosystem function and community composition in a grassland field experiment, thus combining biodiversity and assembly approaches....

Effect of some plant extracts against damping-off disease of some winter vegetable was studied in the net house. Seed treatment with neem leaf, garlic clove, allamonda leaf, ginger rhizome, kalijira seed, bel leaf, turmeric rhizome, katamehedi leaf and onion bulb were evaluated against damping-off, seed germination and growth characters of tomato, eggplant and chilli seedlings. All the treatmen...

Alfalfa (Medicago sativa L. cv. Saranac) seed were soaked for 20 minutes in water, acetone, or methanol containing 10 or 50 mg/ml of oxamyl (Vydate L) or coated with a 2% aqueous cellulose solution containing the same amounts of oxamyl. Seed were analyzed for oxamyl by HPLC immediately after treatment and after 9 and 26 months of storage. Oxamyl content of alfalfa seed did not decline after 26 ...

in order to evaluate a better sowing date of chickpea cultivars in dry land conditions, a factorial experiment in randomized complete block design with four replications was carried out at research station of bahar (hamadan province) during 2005-2006 cropping season. two planting time included winter and spring and four chickpea cultivars (cvs.) including one local (check) and three improved cv...

If the hard seed (seed that is viable but has an impervious coat) content of legumes greater than 20%, scarification should be considered. Scarification nicking coat to allow moisture penetrate [1]. This type treatment before sowing great importance, as it increases yield fodder plants by reducing rate rare and expensive seeds, cost sowing, accelerating germination, increasing percentage germin...

The study was conducted over a period of six months from January to June 2004 to explore the effects of different seed treatments on germination and seedling growth attributes of a popular medicinal plant, Horitoki (Terminalia chebula Retz) in the nursery of Chittagong University, Bangladesh. Seeds were subjected to six pre-sowing treatments e.g. control (T ), depulped (T ), depulped and soaked...

A field experiment was conducted at the Research farm, Division of Agronomy, Sher-e-Kashmir University of Agricultural Sciences and Technology, India for two consecutive rainy (kharif) seasons of 2009 and 2010 to find out the impact of nitrogen, sulphur and farmyard manure (FYM) on growth and yield of sunflower (Helianthus annuus L.). Application of 120 kg N ha significantly increased all the y...

Effects of additional nitrate (20 mol m·3 NO;) on growth of barley (Hordeum vulgare L. cv. Triumph), oat (Avena sativa L. cv. Amuri), rye (Secale cereale L. cv. Rapaki), triticale (x Triticosecale Wittm. cv. Aranui) and wheat (Triticum aestivum L. cv. Otane) prior to emergence from a sowing depth of 70 mm were examined under controlled environment. conditions. For all five cereals, additional N...
