Foliar response of woody ornamentals to sprinkler irrigation with reuse water
… examined foliar damage associated with sprinkle irrigation of reuse water. Reuse water, municipal water and a synthesized saline water were applied via sprinkler irrigation to 20 ornamental tree species. A visual damage index was created based on canopy and leaf level characteristics to assess …

Time of application and rate of depletion of sprinkler irrigation water for selected crops
… available moisture percentage is maintained by irrigation at some value between 25 percent and zero. 2 . The amount and distribution of rainfall at Blacksburg, Virginia in 1950 were such that irrigation was not profitable and even detrimental. Decreased yields of corn under irrigation showed …

Overhead sprinkler irrigation strategies to reduce water and nitrogen loss from container-grown plants
… of intermittent water application via overhead irrigation on water and N leaching, substrate water distribution, and plant growth in a pine bark substrate. Intermittent irrigation was defined as the application of a plants' daily water allotment in multiple applications with prescribed intervals …

AGRONOMIC AND PHYSIOLOGICAL CHARACTERS OF PEARL MILLET (PENNISETUM AMERICANUM L. K. SCHUM) GROWN UNDER A SPRINKLER IRRIGATION GRADIENT (DROUGHT, STRESS, INDEX).
… Tucson, Arizona in 1983 and 1984. A line source sprinkler irrigation gradient was used to create the treatments. Soil moisture and physiological parameters were measured under field conditions at weekly intervals. Growth was analyzed every other week, while yield and yield components were …

Trickle Irrigation; A Study of Moisture Distribution in the Soil Profile
Irrigation in Illinois has increased fourfold in the last decade. Sprinkler irrigation accounts for most of the irrigation in Illinois. While originating in arid regions of the world, trickle irrigation is beginning to receive notice in the humid and sub-humid sections of the United States. Whether …

Laboratory Test Program of Rotary Plate Sprinklers
<br>Sprinkler irrigation is used to supplement natural rainfall on cultivated lands. In 1999 there were approximately 63.0 million irrigated acres in the United States of which 48.5% were under sprinkler irrigation (Irrigation Journal, 2000). Significant portions of these sprinkler systems are …

Effect of irrigation on fertilizer nitrogen requirement, economic returns, and water availability in a corn-soybean rotation
… is extensive research documenting the value of irrigation to increased and/or stabilized yields. Delaying nitrogen (N) applications into the growing season supports more accurate N recommendations and reduces potential for N loss; but delayed applications can pose risks including lower yield. …

ESTABLISHMENT OF TURFGRASS FROM SEED AND SOD IN SAND BASED SYSTEMS COMBINING SPRINKLER AND SUBSURFACE DRIP IRRIGATION SYSTEMS
… establishment of turfgrass using subsurface drip irrigation (SDI) in sand based media has limited success. However, it is unknown if starting with overhead (sprinkler) irrigation and transitioning to SDI can enhance turfgrass establishment. Two experiments were conducted at Stephen F. Austin State …

An analysis of water consumption rates in agricultural irrigation systems
… of the high water consumption rates found in irrigation systems which use projectile-type sprinkler heads, the history and evolution of irrigation systems is discussed. The effect of evaporation is studied as as explanation for the water losses, but it is found to be insignificant. Having …
