Smoke tree (Cotinus coggygria Scop.) is an attractive ornamental tree in landscape that has medicinal properties. In this study, the effects of different levels of salt, cow manure and vermicompost on plant growth were investigated. In a factorial experiment and completely randomized design (CRD), three levels of organic amendments (1- soil 2- 80% v/v soil + 20% v/v vermicompost, 3- 80% v/v soi...
In order to study the efficacy of nicosulfuron in the control of redroot pigweed (Amaranthus retroflexus L.) using adjuvants, a greenhouse experiment was conducted at the Research Greenhouse, Faculty of Agriculture, University of Ferdowsi, Mashhad, Iran. The experiment was carried out as a factorial based on a randomized complete block design with four replications. Treatments included adjuvant...
A study was conducted to evaluate effects of different bone preparation methods on bone parameters and the correlations between bone breaking strength and the other bone parameters. Bone breaking strength is dramatically changed depending on bone preparation methods, whereas other bone parameters such as ash content and ash concentration are not significantly influenced by bone preparation meth...
Sentence determine the stability mechanisms to stress in Agropyron trichophorum at test with four different levels of osmotic potentials resulted from PEG 6000 including 0, -3, -6 and -9 executed in factorial and accidental manner with four interactions in hydroponic environment. Three genotypes of Agropyron trichophorum pasture types were used Arak (3755), Semirom (3.13), and Faridan (4007) an...
an experiment was conducted to determine the effect of paclobutrazol (pbz) and different irrigation amount on growth of aerial parts, leaf minerals and root performance in young olive plants cv. ‘manzanillo’ in the department of horticulture, faculty of agriculture, tarbiat modarres university in 2000. a split plot experiment in time was used based on a completely randomized block design with f...
nowadays, protection of environment and safe agricultural production are an important aims of the sustainable agriculture. also, in attention to abundance of saline soil and water resources in the country, the present research was designed to evaluate pgpr inoculation effect on some morphological and physiological traits of two green bean plant cultivars under salinity stress conditions. a gree...
Climate change and essentiality of the food security have motived scientists to try innovative approaches, among which, crop growth models can help to predict crop yield. In order to simulate tomato (Solanum lycopersicum) growth, phenological characteristics of a short-life variety of tomato were assessed. Phenologic characteristics included leaf area index (LAI), specific leaf area (S...
Plant growth and development was affected greatly through salinity. Appropriate nutrients application on salinity condition can reduce its harmful effects and increased productivity of salinized soils. A pot experiment was carried out in 2007 in cs Lab., Department of Agronomy, Kyungpook National University, Korea to assess the effects of potassium nitrate on Gycine max (Var. Daewonkong) under ...
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, ...
the effect of electromagnetic field was examined on zinnia (zinnia elegans) seeds to enhance seed germination and early growth. the seeds were exposed to four magnetic strengths of 15, 100, 400 and 800 mt in four durations of 30, 60, 120 and 240 min. the experiments were carried out in two forms of laboratory germination and soil emergence. results showed that magnetic field application enhance...
