Surface water in the Deschutes Basin of central Oregon has been largely over
allocated since the early 1900s. Therefore, rapid population growth and urban
demand for water in the upper Basin lead to an increased reliance on groundwater in
the...

Implementation of a small-scale irrigation project in southern Mauritania is analyzed in
this report. The main objective is to demonstrate that small-scale irrigation farming is
the best suited solution for Mauritania's agriculture. To reach this...

Furrow irrigation is the dominant practice for irrigating row crops in the
western Treasure Valley region near Ontario, Oregon. Though improvements
have been made in management practices over the years, excessive runoff and
deep percolation are...

Field experiments were conducted with cauliflower (Brassica oleracea var.
botrytis cv. Snowball Y ) to determine crop development, yield, quality and
maturity response to various seasonal water levels, and to specific water stress
timing in...

This study was prompted by the need for improving the efficiency of irrigation
systems at the Oregon South coastal areas. Accurate information about
evapotranspiration (ET) rates is essential for maximizing the efficiency of irrigation
systems....

Over the past decade, Oregon State University Malheur Experiment Station
at Ontario, Oregon, has evaluated drip irrigation on potato. We have investigated crop response to drip tape flow rate, bed conformation,
drip tape placement with respect to...

In order to understand the economics of the 2001 irrigation curtailment in the Upper Klamath Basin, and the prospects for lower-cost solutions
to future irrigation shortfalls, one must appreciate just how much the economic value of irrigation...

Centrifugal irrigation pumps discharge fluids at high velocities that must be slowed
to minimize energy losses due to friction. Pipe expansions make the transition to larger
pipes associated with slower velocities. Expansions convert the upstream...

More than 4.5 million acres in the Pacific
Northwest are irrigated with electric-powered
sprinkler systems. Center pivots are used on about
1.25 million acres. Irrigation runoff can be a problem
on many of these sprinkler-irrigated fields.

Seedlings of Acacia senegal were grown in a glass greenhouse to study the effect of nitrogen and irrigation regimes on dry matter
production and allocation to different plant organs, net photosynthesis per unit leaf area, and nitrogen content in...
