Water and Crops

Dear Colleagues,

Arid and semi-arid areas are short of fresh water resources. In order to obtain a certain total crop yield, some low-quality water, such as muddy water, urban sewage and industrial wastewater, brackish water and irrigation return water, should be used for irrigation. In addition, the stratified irrigation technology of reservoir and rainwater collection technology in hilly area are effective means to make full use of precipitation and bring the limited water resources into play to increase production.

The comprehensive utilization of agricultural water resources, it is from the perspective of the whole, the whole process from crops irrigation during whole growth period, the reasonable treatment of a variety of different water sources such as surface water, precipitation, ground water and brackish water, urban sewage and industrial waste water to make the best use of, in order to give full play to the role of the existing water resources in the benefits. Optimal management refers to the optimal collocation and allocation of various water sources in different regions, different crops, different growth stages of crops and different soil conditions while making comprehensive utilization. At the same time, the overall benefit can be achieved as high as possible while the adverse impact can be reduced to the lowest level. This special issue will provide a platform for research that will assess the impacts of water on crops.  We seek both application studies and methodological studies that focus on the interaction of water and other factor. The topics covered by this Special Issue will include but not limited to the following:

• Crop water relations, crop yields and water productivity.
• Rainwater harvesting and crop water management in rainfed areas.
• Implications of groundwater and surface water management on nutrient cycling.
• Irrigation, drainage, and salinity in cultivated areas.
