the nitrogen (n) nutrition, crop yield, and responses of wheat to arbuscular mycorrhizal fungi (amf) were tested in an experimental field under free-air ozone concentration [o3] enrichment (face) conditions. the experiment included three treatments: ambient [o3] (ambient), elevated [o3] (face, targeted at ambient [o3]×1.5), and elevated [o3] inoculated with an amf consortium consisting of sever...
Response to five different inoculation treatments has been determined in a three-year-old prairie area established at the Becker Sandplain Experiment Station in Fall 2004. Seed inoculation was generally ineffective, but overall legume numbers and biomass in the prairie restorations were enhanced by both soil-applied granular and cover-crop applied inoculants, with soils collected from the prair...
tomato seedlings were inoculated with t. harzianum bi (106 spores/ml) and salicylic acid (5mm) other separately or combined together in the greenhouse environment. the effect of salicylic acid was investigated on growth of antagonistic agent in vitro. for an investigation of the effect of salicylic acid and of antagonist on pathogenecity factor, treatment with t. harzianum bi by drenching soil ...
abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
the research questions were as follows: 1. is there any relationship between the students concious awareness of the form and implications of the conjuncations and their improvement in using appropriate conjunctions? 2. does students knowledge of the from and the implications of the conjunctions help them to produce more coherent writings. 3. does a comparison between english conjunctions and th...
This study used a [(13)C]DNA stable isotope probing (SIP) technique to elucidate a direct pathway for the translocation of (13)C-labeled photoassimilate from maize plants to extraradical mycelium-associated phosphate-solubilizing bacteria (PSB) that mediate the mineralization and turnover of soil organic phosphorus (P) in the hyphosphere. Inoculation with PSB alone did not provide any benefit t...
To evaluate the inoculation effect of potassium releasing, phosphate solubilizing and nitrogen fixing bacteria on the fruit quality of tomato, an experiment based on randomized complete block design with 9 treatments and 3 replications has been conducted. In this experiment, tomato (super chief cv.) seedlings of the in the treasury cultivation with single and combined treatments of the potassiu...
the central purpose of this study was to conduct a case study about the role of self monitoring in teacher’s use of motivational strategies. furthermore it focused on how these strategies affected students’ motivational behavior. although many studies have been done to investigate teachers’ motivational strategies use (cheng & d?rnyei, 2007; d?rnyei & csizer, 1998; green, 2001, guilloteaux & d?...
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...
