Surface irrigation is the dominant method of on-farm irrigation in Egypt as well as world wide. Furrow watering is considered as one of the main types of surface irrigation. Most of the cultivated crops are grown under such type of watering. The principal advantage of furrow irrigation is the less irrigated area comparing with that under basin irrigation which equaled total cultivated acreage. ...

Water is one of the most natural resources for all the living organisms, weather unicellular or multi cellular, since it is required for various domestic purposes irrigation, power generation and industries. In a freshwater system, the zooplankton forms are important group and constitute basic link of the food chain. Planktons are very sensitive to the environment they live in and any alteratio...

Pollution levels have been increasing in water ecosystems worldwide. A water quality index (WQI) is an available tool to approximate the quality of water and facilitate the work of decision-makers by grouping and analyzing numerous parameters with a single numerical classification system. The objective of this study was to develop a WQI for a dam used for irrigation of about 5000 ha of agricult...

In the absence of available surface water in semi-arid areas, groundwater has become the main water resource for various purposes. In many places in southern India, groundwater even is the only source of drinking water in rural areas. Therefore, quality and quantity aspects of groundwater management constitute acute issues for the well-being of Indian rural populations. This study proposes to u...

high yield of top quality crop is a prerequisite for profitable production of greenhouse produced cucumber. on the other hand, because of water deficit in iran it is necessary to economize in this scarce and valuable input. an experiment was carried out in the experimental greenhouse of university college of agriculture and natural resources, university of tehran to optimize water use in soil c...

Increasing water use efficiency and reducing nitrogen pollutant discharge are important tasks for modern agriculture. To evaluate the effect of alternate partial root-zone irrigation (APRI) on tomato plant growth, water use efficiency and nitrate-15N uptake, an experiment was conducted from June to December in 2014 under greenhouse condition in northern China. The experiment contained two irrig...
