in order to compare planting season effect on agronomic of characters and yield of dill (anethum graveolens l.) an experiment based on completely randomized design with three replications was conducted in 2006-07 in esfahan province and three planting seasons (spring, summer and autumn) were evaluated. essential oil compositions were obtained by clevenger and recognized by gc-mass and gc. accor...
abstract chickpea is weak in competition of weeds that damages to it at between 40 t0 60 percent. kermanshah province is one of the most important region for chickpea fields in iran. for these reosons, weed management is necessary in this crop. in order to evaluate of herbicides and stubble control on broad leave weeds control in chickpea. experiment was conducted in agricultural research stat...
in order to study the effect of sowing methods and seeding rates on fodder yield and some agronomic characters of nikshahri alfalfa ecotype, an experiment was conducted in a split plot arrangement in randomized complete block design with four replications in the field of agricultural and natural resources center of baluchistan in iranshahr region. in this study, sowing methods: hand spread, 12 ...
in order to study the effects of vermicompost and biological fertilizers on vegetative yield and essential oil of basil (ocimum basilicum l.), an experiment was conducted based on a complete randomized block design with nine treatments and three replications at mashhad during growing season of 2009-2010. the treatments were: 1) vermicompost, 2) nitroxin (included: azotobacter sp. and azospirill...
in this study, a simple, rapid and selective method was developed for the determination of dexamethasone. the proposed method is based on inhibitory effect of dexamethasone on the oxidation of orange-g by bromate in sulfuric acid media. the reaction was followed spectrophotometrically at 478.5 nm (?max). under optimum experimental conditions, (72.6 ?mol l-1 of orange-g, 0.76 mol l-1 of h2so4, 0...
in this study, the effects of oleothermal modification on physical and mechanical peroperties of fir wood (abeis sp.) blocks were examined. at first, some blocks of fir wood with 5 × 20 × 120 cm dimensions were prepared. the blocks were treated in soybean oil. the effects of 3 factors such as treatments temperature (180and 200 °c), holding time (12 and 15 h) and initial moisture content of wood...
To survey the effects of chemical and biological phosphorus on the yield and essential oil of Satureja hortensis L. as an important medicinal plant, factorial experiment was conducted based on randomized complete block design with three replicates at Research Station of Faculty of Agriculture, Urmia University in 2011. The treatments were chemical phosphorus fertilizer with four levels (0, 50, ...
In order to investigate the effects of sowing date on yield and some agronomic traits of six forage maize hybrids, two experiments were conducted in 2009 in two locations including Rasht and Fuman. The experimental design was randomized complete blocks with factorial arrangement and three replications. Treatments consisted of three levels of sowing date (31 May, 13 and 26 June) and six maize hy...
fluorescence chemical sensors for the highly sensitive and selective determination of pb2+ , hg2+, co2+ and fe3+ ions in aqueous solutions are described. the ion sensing system was prepared by incorporating lipophilic ligand (l) as a neutral ion-selective fluoroionophore in the plasticized pvc membrane containing sodium tetraphenylborate or potasium tetrakis (p-chlorophenyl) borate as a liphoph...
