To decrease adverse effects of water deficit is foliar application with chemical agents such as silicon. However, there is low information on the influence of silicon on alfalfa under drought stress conditions. Thus, the current study was conducted to assessment the effect of different silicon concentrations (0, 1 and 2 mili Molar concentration) on alfalfa growth trend and biochemical traits, w...
heuristics are often used to provide solutions for flow shop scheduling problems.the performance of a heuristic is usually judged by comparing solutions and run times on test cases.this investigation proposes an analytical alternative ,called asymptotic convergence ,which tests the convergence of the heuristic to a lower bound as problem size grows. the test is a stronger variation of worst cas...
in order to evaluate the effects of irrigation levels and foliar application with fe and zn on quantitative and qualitative traits of red bean, an experiment was designed as split plot based on a completely randomized block design with three replications in lordegan country in summer 2011. irrigation as the main plot at three level such on: irrigation after 50, 75 and 100 mm evaporation, and fo...
background and objectives: over the last two decades, a large number of researches have been conducted regarding the importance of nitrogen in sugar beet. this indicate that there were needs to investigate more on nitrogen management to achive higher production and quality because less nitrogen application result in reducing yield and high nitrogen application would increase production costs an...
The use of micronutrient fertilizers, such as zinc on the condition of natural limiting factors such as salinity can be a great help in the development of medicinal plants cultivated in many parts of the country. In order to study the response of Plantago ovata to zinc application under salt stress, a pot experiment was conducted in 2013, as factorial experiment based on a complete randomized d...
The required water for greenhouses in Kishestan, Soume-e-Sara town, Guilan province, Iran, is mainly provided by underground resources that have inappropriate quality. One way to reduce the impact of salinity an plant growth is proper nutrition. This greenhouse research was conducted to evaluate the effect of water salinity and foliar spray of calcium (Ca) and silicon (Si) on growth and vase li...
nitrogen is one of the most important and essential lelments for plant growth and development and it has an important role on quantitative and qualitative yield production in agriculture. this study was carried out to evaluate the effects of foliar application of nitrogen on qualitative traits of tomato fruits using a completely randomized design with five treatments and four replications under...
this ethnographic case study research was carried out in a private school setting in the context of iran. the research tried to explore the analysis and identity construction of a group of learners and teachers along with the content analysis of books on the basis of four types of commodified, political, national and narrative identities. how english language learners and teachers in an informa...
abstract previous researches have shown success of growth hormones usage on flower production increase, pod and prevention of abscission of them in some of the pulses. two tests were done, in order to find out the effects of growth hormones to on flower production increase, pod and chick pea yield composites in farmer conditions (2010-11) and green house conditions as factorial on the proje...
Drought stress is a major environmental stress that restricts plant growth and production in the majority of agricultural fields of the world. The application of different fertilizers, especially biofertilizers and organic fertilizers, might play an important role in the production of medicinal plants in order to improve their resistance to deficit water stress. In order to evaluate the effects...
