introduction: production and growth of plants in many parts of the world due to degradation and water scarcity have been limited and particularly, in recent decades, agriculture is faced with stress. in the most parts of iran, especially in the khorasan razavi province, drought is a fact and water is very important. due to melon cultivation in this province, and the conditions of quality and qu...
Limitation of suitable water resources is the most important problem of agriculture in Iran. Considering the condition of shallow and saline groundwater in many parts of Iran, and relative resistance of safflower to salinity, it is necessary to study the contribution of groundwater to water consumption of safflower. In this research, the effects of different water table depths and salinity of g...
This study included two experiments conducted in 2000-2001 for surveying the effects of saline water irrigation on yield and yield components in corn varieties. Experiments were conducted in a silty-clay soil in Ahwaz Agricultural Research Center. First experiment was conducted as a split plots and randomized complete blocks design in three replications. Main plots included salinity levels 2, 4...
Pakistan’s Irrigation system is more than a century old, the distribution system within any canal command is designed to distribute the canal water equitably ignoring rainfall patterns and underlying groundwater resources. Now, the groundwater contribution in meeting crop water requirement has even crossed the canal water supply in the existing scenario of increased cropping intensities. The un...
In Guilan province, Sefidrud River, as the main source of irrigating rice in Guilan province, has been subjected to increasing salinity and a decreasing discharge because of decreasing in the volume of sefidrud dam, diverting water upstream and entering different sewages into the river. This research tries to determine optimum irrigation depth and intermittent periods in proportion to salinity ...
Dear Editors, Tap water therapy has been used for several decades (1) in wound cleansing for the treatment of many conditions, such as lacerations, incisions, open fractures and episiotomy (2–5). The infection rate and outcome of wounds cleansed with tap water are commonly believed to be the same as those cleaned with normal saline solution (2–5). Even though this alternative treatment is consi...
abstract environmental pollution has made urban citizens to focus on landscapes. in this respect lown is very important plant. from the other hand water resources in many arid and semi-arid region is saline. for this purpose a research was conducted to study the effect of sprinkling irrigation with saline water on growth parameters of three lown varieties. these varieties were poa partensis, fe...
Abstract In China, fresh water resources are scarce, while brackish abundant. Reasonable utilization of is one the important measures to alleviate contradiction shortage. order study effect irrigation on and salt transport in saline-alkali soils, one-dimensional infiltration experiments soil columns were conducted. The influence with different salinities salinized was compared analyzed. results...
