Therefore, water-use-efficient irrigation and regulated deficit irrigation programs need to be developed to improve water-use efficiency, crop productivity and quality in semi-arid crops.
Water availability was reduced greatly between the late 1970s and the 1990s because of irrigation programs in the catchment area, which exhausted the groundwater aquifer, and their effects on plants were mediated by decreasing yearly average flooding and its variability.
A $3.50 hand pump to transfer water from a storage bag to a drip-system gravity tank looks promising, and a $4.50 , 200-literpolyurethane bag might be an improvement on the $10 cost of the larger drip system's plastic barrel, particularly since IDE is shipping the drip systems out of India to its irrigation programs in Zambia and Zimbabwe.
(Besides new bunkers, the green received what sounds like a spa treatment: a complete de-mucking and re-irrigation program designed to use 30% less water).
"Every time they would build a plant, it would raise our rates," says Terry Ketterling, a farmer in Mountain Home, Idaho, who grows sugar beets, corn, wheat and alfalfa and who, like Mr. Erwin, participates in the irrigation payment program.
He gave his time and talent to numerous Israeli and American Jewish causes including the Jewish Funds for Justice in which he established the Drip Irrigation Agricultural program, used in Israel, for the Navajo Nation.
This paper describes the Landscape Irrigation Management Program (LIMP) model, which addresses these problems.
The irrigation improvement program implemented by MWRI aimed to modernize Egypt's irrigation system through improvement of infrastructure and establishment of Water Users Organizations WUOs.
This work provides an intervention free process for extracting plant water stress information which can be fed into an automated irrigation scheduling program.
