such aabiotic stresses like water stress are some of the most important threats to the production of agricultural crops. it is almost very rare to find a place with no stress where plants can reach their potential yield. a water stress of 17 percent decrease yield, due to its effect upon fruit setting is notable. therefore, a study was conducted in bushehr agricultural research center (located ...

background and objectives: soybean (glycine max l.) is the most important oil crop having the largest area under cultivation in the world. every year, water stress causes great damages on crops in the world, particularly in iran with arid and semi-arid climate so application of materials such as zeolite in soil can reduce the adverse effects of water stress. however, the effect of zeolite in in...

plant analysis is successfully used in monitoring nutritional status, recommending fertilizer rates and types, and maximizing fertilizer efficiency in sugar beet. diagnosis and recommendation integrated system (dris) is a comprehensive approach which does not have limitations of the critical value approach (cva) and sufficiency range approach (sra). over- dose application of fertilizer increase...

background and objectives: over the last decade, climate change has been one of the most challenging issues in the scientific papers. studying the impacts of climate change on crop productivity at regional scale will depend on the right estimate of future climate. this estimation is being implemented by climate models and most of them by general circulation models (gcms). this study aims at pre...

objective: high-intensity interval training (hit) is an efficient means of improving performance in a short period of time. the effects of hit program on performance, physiological and resting levels of growth hormone (gh) , igf-1,igfbp-3 and cortisol in elite athletes are not well known. methods: so, the present study was conducted to show the effect of four weeks hit on some functional and ho...

to study the effect of harvesting time on soybean seed germination and vigor a factorial experiment with three replications, including of five harvesting time and three soybean cultivars was carried out in the field and glasshouse. the effect of harvesting time on seed germination percentage (in the field, cold test and paper test), seed germination rate, shoot and root weights, 1000-seed weigh...

many of the meteorological variables such as precipitation, strongly depend on the large scale atmospheric and ocean surface circulations.in the current study, the effect of climatic signals on the average monthly rainfall of the adjacent stations of sheshdeh and gharebolagh area was investigated during the statistical period twenty five years from 1985 to 2009. the regression and neural networ...
