SUBSURFACE DRIP IRRIGATION AND UREA PHOSPHATE USE IN VEGETABLES ON CALCAREOUS SOILS.
Drip irrigation lines placed 15 cm deep or 5 cm shallow below soil surface and furrow irrigation were compared on calcareous soils of southern Arizona. Crops grown were zucchini squash (Cucurbita pepo L.) 1982 and 1983 summers, and cabbage (Brassica oleracea var. capitata L.), 1982 fall. Furrows …

ESTABLISHMENT OF TURFGRASS FROM SEED AND SOD IN SAND BASED SYSTEMS COMBINING SPRINKLER AND SUBSURFACE DRIP IRRIGATION SYSTEMS
<p>The 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 …

Optimizing Corn and Cotton Performance with Adaptive Management Systems and Subsurface Drip Irrigation in the Mid-Atlantic USA
… corn and cotton fields irrigated, increased irrigation adoption could stabilize/increase crop production outcomes in this region. Three studies were conducted to evaluate these management strategies with the following objectives: 1. To compare standard farmer practices with the Adaptive Corn …

Evaluation of Modern Irrigation Techniques with Brackish Water
Modern irrigation techniques are becoming increasingly important in water-scarce countries especially in arid and semiarid regions. Higher crop production and better water use efficiency are usually achieved by drip irrigation as compared to other irrigation methods. Furthermore, by using drip …

Deficit Irrigation Strategies on young orange trees (cv Tarocco Sciara)
… to optimise water resources is to employ deficit irrigation (DI) strategies. DI effects on some physiological characters of young orange orchards were analysed. The orchard includes 300, 4-years old, plants located at the CRA-ACM experimental farm in Lentini, Sicily (37° 20 N; 14° 53 E). Four …

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. …

Agronomic and nutritional considerations for increased soybean productivity
… in-season applications of N, K, and S using a subsurface drip irrigation (SDI) system and improved seed yield by as much as 357 kg ha-1. Do other agronomic decisions such as variety selection influence the responsiveness to nutrient supply? Results indicated that variety selection significantly …

Remote sensing-based assessment of crop yield and water dynamics in the southern Great Plains (USA)
… compared and evaluated different precision irrigation systems using ETc. The overarching goal was to identify field-scale crop water stress and irrigation scheduling. Therefore, we have utilized and quantified satellite-derived ETc to evaluate different irrigation systems that can save …
