Thyme (Thymus vulgaris L.) is an important medicinal plant with highly valuable essential oils. In this study, effects of different fertilizer treatments and cuts on Thymus vulgaris L. was evaluated in 2008-2009. The research was conducted at Alborz Research Station, Research Institute of Forests and Rangelands, Karaj, Iran. The Experimental design was split plot in time in the form of a random...
abstractbackground and objectives the oilseeds after cereal, the world's second largest food supply make up. environmental stress has always been one of the most important factors reducing crop yield and production are gone and counter or reduce the effects of stress as a useful strategy to increase the quality and quantity of the products has been considered. flooding conditions are said ...

results the chemical analysis of s. khuzestanica essential oil revealed the presence of carvacrol (94.1%) as its main component. the inhibition zone diameters of s. khuzestanica essential oil and carvacrol dose-dependently increased. the minimum inhibitory concentration (mic) values of s. khuzestanica essential oil and carvacrol were 0.14 ± 0.08 µl/ml and 0.09 ± 0.04 µl/ml, respectively. s. khu...
While previous research has been contradictory, potential grain yield responses and seed protein increases have led to con tinuing interest in N fertilizer application to soybean (Glycine max (L.) Merr.]. Field experiments were conducted at seven lo cations from 1990 to 1991 in Alabama to determine soybean response to N fertilization at various growth stages. Treatments included a factorial a...
In order to determine the interaction of residual nitrogen (N) and different N rates on seed and oil yield of rapeseed, an experiment was conducted at Shahrekord University, Shahrekord, Iran, in 2008-2009 growing season. The experimental design was split plots arranged in randomized complete block design with three replications. Seven treatments of residual N (217, 435 and 652 kg/ha from urea...
background & aim: the world production and consumption of essential oils and perfumes are increasing very fast. lippia citriodora h.b.k. is an herbal species mainly used as a spice and medicinal plant. endogenous levels as well exogenous application of plant growth regulators (pgr) could affect essential oil production and chemical compositions. experimental: to study the effect of exogenou...
Growth and biochemical performance of Manihot esculenta Crantz (TMS 0505) amended with Centrosema pubescens and NPK fertilizer were carried out. Contamination levels of 2%, 4%, and 6% were used while amelioration treatments C. pubescens and NPK 15:15:15 were carried out by adding organic supplement (decomposed Centrosema pubescens) and NPK at the rate of 0.25Kg per 5Kg of soil to the various le...
In order to study the effects of different levels of nitrogen fertilizer and plant density on grain yield and its components in sunflower, an experiment was conducted using 'Record' cultivar at the Research Farm of College of Agriculture, Isfahan University of Technology in 1996. Four levels of nitrogen (0, 75, 150 and 225 kg/ha) and four plant densities (65000, 75000, 85000 and 95000 plants/ha...
