Research has not been conducted in Arizona to determine when to irrigate wheat based on soil water depletion levels. The purpose of this work is to establish the optimum irrigation timing based on depletion of plant available water in the soil. A field experiment was conducted at the Maricopa Agricultural Center testing irrigation of wheat at 35, 50, 65, and 80% depletion of plant available water in the soil for two durum varieties, Kronos and Westbred 881. Grain yields averaged over the two varieties were 6479, 5099, 4283, and 4145 lbs/acre for the 35, 50, 65, and 80% depletion levels, respec

Abstract:

This research was conducted to test the effect of soil water depletion levels on durum productivity. An experiment was conducted at a commercial farm in Stanfield where irrigations were applied at 35, 50, or 65% depletion of plant available soil water. These soil water depletion levels were estimated from soil texture and weather data. The grain yields obtained with 35, 50, and 65% depletion were 6718, 6324, and 4752 lbs/acre, respectively. Grain protein decreased and HVAC increased by irrigating more frequently at lower depletion levels. Irrigating at 50% depletion was the most economical in

Half of the experiments were preceded by volume depletion (median 1.7 L) with furosemide. A visual analogue scale (0-100 mm) was used to assess perceived thirst during each experiment.

Significant differences in estimated total phosphorus export rates across treatments were found.

Abstract:

碩士<br>國立中興大學<br>獸醫學系暨研究所<br>104<br>The recommended use of doxycycline (DC) is 100 ppm via drinking water for 3-5 days, and its withdrawal time (WDT) is 7 days. However, the applied concentration in field is usually doubled, rendering concern of possible tissue residues exceeding the maximum residual levels (MRLs). The study is aimed to evaluate tissue depletion of DC in broiler when the drug is applied in drinking water at 200 ppm (approximately equal to 40 mg/kg BW) for five consecutive days in line with the field condition. Serum drug concentrations during and 24-hr post-medication were also

碩士<br>國立臺灣海洋大學<br>水產養殖學系<br>99<br>The objective of the present study was to investigate the effect of bath treatment of different concentrations (0.5, 1.5, 3 mg/L) of benzalkonium chloride (BKC) on its residue depletion in red tilapia (Oreochromis spp.), water and soil. In red tilapia, fish following bath treatment with different does of BKC had water replacement after 24 houres. Sample of gill, serum, liver, skin, muscle were collected at 2, 4, 8, 16, 24, 48, 120, 192, 360, 720, 1440 hours post dose and were analyzed for BKC main components, which were BKC-C12 and BKC-C14. Different BKC conce

Abstract:

A novel mode of shallow aquifer management could increase the volumetric potential and distribution of underground, freshwater storage: Shallow aquifer storage and recovery (SASR). In this mode, water is efficiently stored in basin fill aquifers with strong hydraulic connection to surface water. Regional numerical modeling can provide a linkage between storage efficiency and local hydrogeologic parameters, which in turn may contribute to useful rules guiding how and where water can be stored. This study: (1) uses a calibrated model of the central Willamette Basin (CWB), Oregon to correlate SAS

Abstract:

Introducing effective irrigation management in arid and semi-arid regions, like most areas of South Africa, is an indispensable way of maximising crop yield and enhancing productivity of scarce freshwater resources. Holistic improvements in agricultural water management could be realised through integrating the knowledge of crop-specific water requirements. In order to develop effective irrigation schedules for rose-scented geranium (Pelargonium capitatum x P. radens), greenhouse and field experiments were conducted at the Hatfield Experimental Farm of the University of Pretoria, Pretoria, Sou

Abstract:

Stormwater runoff has negative impacts on water resources, human health and environment. In this research the effectiveness of Rain Water Harvesting (RWH) systems is examined as a stormwater Best Management Practice (BMP). Time-based, evapotranspiration-based, and soil moisture-based irrigation scheduling methods in conjunction with RWH and a control site without RWH were simulated to determine the effect of RWH as a BMP on a single-family residence scale. The effects of each irrigation scheduling method on minimizing water runoff leaving the plots and potable water input for irrigation were c
