The rate of evaporation of drops of dibutyl phthalate and butyl stearate of radius approx. 0*5 mm. has been studied by means of a microbalance over a range of atmospheric pressures down to approx. 0*1 mm. of mercury. Wide departures from Langm uir’s evaporation formula were found to oceur a t these low pressures, bu t results are in good acoordance with the theory of droplet evaporation advance...

for determination of irrigated sugar beet crop evaporation (etc) and water consumption a field experiment was conducted for three years (1991 to 1993)  in kabotar-abad agricultural experiment station. the climate was semi-arid according to gossen method with mean annual precipitation of 90 to 110 mm. the soil was esfahan series with a silty clay loam texture. the crop evapotranspiration was mea...

limited information is available on water and nitrogen (n) management of sugarcane (saccharum officinarum l.) in khuzestan, southwestern iran, where this crop is currently and extensively grown under heavy irrigation and n fertilization. therefore, a field experiment was conducted from september 2000 to march 2002 at the research department of karoon agro-industry in khuzestan to determine the ...

The complementary relationship between actual and potential evaporation over southeastern Turkey was examined using a mesoscale climate model and field data. Model simulations of both actual and potential evaporation produce realistic temporal patterns in comparison to those estimated from field data; as evaporation from the surface increases with increasing irrigation, potential evaporation de...

the purpose of this study is evaluation and improvement of production functions to estimate alfalfa yields under different deficit irrigations conditions and determination of “production of yield - water use” in qazvin plain. this investigation was applied by factorial experiment in a randomized complete block design with four water treatments including e4, e3, e2, and e1, respectively, equal t...
