the aim of this study was to investigate the effects of winter crops residues on weed control, physiological indices, yield and yield components of potato. an experiment was carried out at the research farm of colleg of agricultural of bu-ali sina university in 2009. the experiment was a randomized complete block design with three replications. residues of rye, oilseed rape, triticale, barley, ...
This study was performed in order to determine the distance of isolation for the seed potato production from ware potato in three regions of Ardabil, Namin and Nir. The experiment was carried out in a randomized complete block design (RCBD) with five distances (100, 200, 300, 400 and 500 meters from ware potato) and three replications with Super Elite (SE) class of Agria potato cultivar from wa...
in civil engineering concrete is a material combined of hydraulic cement, sand, gravel and water. gravel and sand compose 60 to 70 percent of concrete. these aggregates support compression force of concrete. cement paste acts as glue to stick grain together. in bushehr factories producing aggregates do not operate according to astm standards, so that fineness modulus (fm) of the produced sands ...
In order to detect the reaction of different potato genotypes to different irrigation regimes and evaluate their water productivity, a research was carried out as a split plot experiment based on a randomized complete block design with three replications in Agricultural Research Center and Natural Resources of Ardabil, Iran in 2015-2016. Five potato genotypes (Agria, Caesar, Savalan, 397081-1 a...
to evaluate the effect of water, tape drip and furrow irrigation methods on the performance components and features of agria cultivar potato, an experiment was carried out in the agriculture faculty of kermanshah. repeated three times, this study was carried out in the form of full random blocks with the main factor of different amounts of irrigation water in three levels (50, 75, and100 percen...

1 We used a combination of laboratory and field experiments to test the hypothesis that the burial depth of Potamogeton pectinatus tubers will vary with local sediment type and swan predation pressure. 2 In the field, mortality due to predation by swans decreased linearly with burial depth (from 100% at the surface to 55% at 225 mm depth) and with sediment clay content. Average tuber size showe...
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...

INTRODUCTION The aim of this study was to document the morphological and topographical anatomy of the infraorbital foramen (IOF) in relation to the infraorbital rim (IOR), which is necessary in clinical situations that require regional nerve blocks. METHODS A total of 80 dry South Indian adult human skulls of unknown age and gender were studied. In each skull, the IOF on both sides was measur...
