in this paper, a new framework has been developed for compatibility analysis of predictive climatic variables distribution with reference evapotranspiration (eto) in probabilistic analysis of water requirement. initially, measured monthly meteorological data of four cities of iran including kerman, shiraz, ramsar and babolsar synoptic weather station recorded from 1961 to 2003 were considered b...

ِdfferent drip (surface and subsurface) and furrow irrigation methods effects on grain, oil and water use efficiency based on grain black cumin(nigella sativa l.) as medicinal plants was investigated. for this purpose, experiment over the past two years (2009 and 2010) in a randomized complete block was designed in three replications. treatments in this research were consisting of 50, 75 and 100...

lorestan and khorramabad province has major share in chickpea production region are the one of the largest producer of chickpea (cicer arietinum l.) in iran, chickpea with more cultivation area compare to the other plants, to estimate the chickpea water requirement. the aim of this research was to determine the crop coefficients of chickpea in a research field in lorestan agriculture faculty in...

in order to investigate the effect of domestic wastewater and normal water (well water) on soil chemical properties and alfalfa yield, a research project was conducted for three years in chahartakhteh research station. the experiment was performed in randomized complete blocks design including four treatments in three replications. treatments were as follows: t1: irrigation with normal water at...

I. Three experiments involving sixty-two growing-finishing pigs from 28 to 90 kg bodyweight were conducted to investigate the effect of environmental temperature on the thiamin requirement of growing-finishing pigs. Three temperatures (zoo, 30' and 35") were used. 2. Under these experimental conditions, average daily weight gain indicated no effect of environmental temperature on thiamin requir...

using modern irrigation methods such as border irrigation is one way for an optimum usage of water. potato, for this study, was cultured in a farm located at kermanshah faculty of agriculture to evaluate the efficiency of border irrigation. the culture potato was the agria variety and the applied treatment were 50, 75, and 100 percent of potato plant`s water requirement. tapes were 12 m and the...

The Silver Impregnated Porous Pot (SIPP) filter is a product of the Tshwane University of Technology manufactured for the production of safe drinking water at a household (home) level. Two SIPP devices were assessed for the reduction efficiency of chemical contaminants such as calcium, magnesium, iron, arsenic, fluorides and total organic carbon (TOC) as well as microbial contaminants from envi...

The post-larval or puerulus stage of spiny, or rock, lobsters (Palinuridae) swim many kilometres from open oceans into coastal waters where they subsequently settle. The orientation cues used by the puerulus for this migration are unclear, but are presumed to be critical to finding a place to settle. Understanding this process may help explain the biological processes of dispersal and settlemen...
