Consideration of Water Productivity for Farm Water Management in Different Conditions of Water Availability for Dominant Summer Crops
ABSTRACT- Efficient use of irrigation water for summer crops should be considered seriously due to rare occurrence of precipitation in summer. This research was focused on the assessment of water use efficiency for dominant crops of summer cropping pattern in the study area (i.e., maize and rice) via considering water productivity (WP) with different water management scenarios at farm level at ...
متن کاملWater Saving under Alternative Furrows Surface Irrigation in Clay Soils of North Nile Delta
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. ...
متن کاملWater-saving irrigation strategies affect tuber water relations and nitrogen content of potatoes
The dynamic and static deficit (DDI, SDI), partial root drying (DPRD, SPRD) and full (FI)irrigation strategies were applied in Agria and Ramos potato cultivars in a semi-arid area. FIreceived 100% of the potential evapotranspiration (ET); SDI and SPRD received 75% of ETduring the growth period; DDI and DPRD received 90% of ET in the first third, 75% of ET inthe second third and 50% of ET in the...
متن کاملA Dynamic Decision Support System for Farm Water Management in Surface Irrigation: Model Development and Application
An online dynamic decision support system (DDSS) was developed, to support the farm water management in surface irrigation. The online DDSS was based on the formulation and integration of three components: a dynamic-relational data base, an administrator model, and a graphical user interface. The DDSS allows routines of actualization, edition and addition of online data, providing information i...
متن کاملImpact of water and nitrogen management strategies on maize yield and water productivity indices under linear-move sprinkler irrigation
With uncertainty in future irrigation water availability and regulations on nutrient application amounts, experimentally determined effects of “controllable” management strategies such as nitrogen (N), water, and their combination on crop water productivity (CWP, also known as crop water use efficiency) and actual evapotranspiration (ETa) are essential. The effects of various N application rate...
