Extended Abstract Introduction and Objective: Various environmental stresses, especially water deficit stress have several and major effects on maize growth and production. Drought is one of the abiotic stresses that due to the great variety of rainfall conditions, it is known from Iran as the most important factor limiting the growth and production of crops. Therefore, the effect of water def...

Redroot pigweed (Amaranthus retroflexus L.) is a noxious and cosmopolitan weed that is widely distributed in different parts of the world and competes severely with crops and reduces their growth and yield. The present study was conducted to investigate the effect of drought stress on some morphological and physiological characteristics of redroot pigweed in 2018 and 2019. Treatments included d...

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

In order to investigate the genetic diversity and the heritability of oil and protein content of grain in confectionary sunflower under different water availability, 56 local populations were studied in three separate experiments with rectangular lattice design (7×8) with two replications at Agricultural Research Center of West-Azerbaijan province, Urmia, Iran in 2012.
