effect of saline water and nitrogen application management at different growth stages on wheat yield
nitrogen is the primary nutrient that shows deficiency in saline areas, therefore, proper nitrogen fertilizer management is one of the strategies to achieve higher wheat grain yield. a field experiments in a saline soil was performed on wheat with a factorial arrangement in randomized complete block design with four replications, in rostagh area, 25 km from yazd. the first factor was nitrogen ...
in the first part of this thesis we explored wetting and its dynamics for small droplets. first, we showed how a simple feature of water droplets on a surface, i.e. laplace pressure, can be exploited to build a micropump. we investigated capillary pumping in microchannels both experimentally and numerically. putting two droplets of different sizes at the in/outlet of a microchannel, will ge...
in order to study a the effect of different levels of ammonium sulfate on photosynthesis pigments, essential oil content and components in summer savory, an experiment was conducted based on randomized complete block design (rcbd) with five treatments and three replications on karaj climate conditions. the treatments included five levels of ammonium sulfate consist of: control (without fertiliz...
gol-e-gohar iron ore mine of sirjan in southern part of iran is a large open pit that operates below the groundwater table and during mining operation, dewatering is required to prevent operation processes from flooding. current operation is going on by digging wells in or out of the pit and pumping to prevent flooding. as a result of the former dewatering operation a vast deep cone of depressi...
Commercial cultivation of blueberry has rapidly expanded in China recent years. However, suboptimal fertilization results poor growth and management practices orchards. The present study studied southern highbush southwest China. We evaluated the effects inorganic nitrogen, phosphorus, potassium fertilizers at different doses. Plant vegetative growth, leaf photosynthesis parameters, fruit quali...
like any other learning activity, translation is a problem solving activity which involves executing parallel cognitive processes. the ability to think about these higher processes, plan, organize, monitor and evaluate the most influential executive cognitive processes is what flavell (1975) called “metacognition” which encompasses raising awareness of mental processes as well as using effectiv...
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...
