The availability of water is a global issue which is predicted to become more pronounced in the future. As a large and relatively dry continent Australia is presented with a series of challenges within the agriculture sector. As a result, the adoption of appropriate, efficient and effective irrigation systems is an important element for future sustainability. In various Australian growing regio...
Field experiments were carried out in Huantai County from 2006 to 2008 to evaluate the effects of different nitrogen (N) fertilization and irrigation management practices on water leakage and nitrate leaching in the dominant wheat–maize rotation system in the North China Plain (NCP). Two N fertilization (NF1, the traditional one; NF2, fertilization based on soil testing) and two irrigation (IR1...
The success of seedling establishment of desert plants is determined by seedling emergence response to an unpredictable precipitation regime. Sand burial is a crucial and frequent environmental stress that impacts seedling establishment on sand dunes. However, little is known about the ecological role of seed mucilage in seedling emergence in arid sandy environments. We hypothesized that seed m...
PURPOSE Preparation of a one-piece dental implant abutment is often needed to achieve a proper emergence profile for a definitive restoration. However, this procedure may compromise osseointegration through the production of heat. The aim of this study was to measure heat production during implant abutment preparation with different volumes of water irrigation using a one-piece implant system. ...
Fruit yield and root system distribution of ‘Tommy Atkins’ mango under different irrigation regimes1
This study aimed to evaluate the fruit yield and the distribution of ‘Tommy Atkins’ mango root system under different irrigation regimes in the semiarid region of Bahia. The experimental design was completely randomized with five treatments and three replicates: 1 Irrigation supplying 100% of ETc in phases I, II and III; 2 Regulated deficit irrigation (RDI) supplying 50% of ETc in phase I (begi...
Water scarcity and salinity are important limitations for saffron (Crocus sativus L.) production in arid and semi-arid regions. The purpose of this research was to study the interaction effects of water salinity and deficit irrigation on the macroscopic water extraction model for saffron. The effect of salinity and water stress on root-water uptake coefficient was determined by additive and mul...
Due to increasing scarcity of fresh water, use of unconventional water source (e.g., wastewater) in irrigation has now become important. However, inclusive information on the effects of wastewater on crop production and soil health is necessary for such intervention. This study was designed to evaluate these effects by demonstrating the contribution of municipal wastewater (hereafter called was...
OBJECTIVES/HYPOTHESIS To compare efficacy and outcome of daily saline irrigation versus saline/gentamicin for treating chronic rhinosinusitis (CRS). STUDY DESIGN Prospective, randomized, double-blinded study. METHODS Forty children diagnosed with CRS were enrolled. Patients were randomized to once-daily irrigation with saline or saline/gentamicin for 6 weeks. Treatment outcomes were measure...
Automatic irrigation scheduling based on real-time measurement of soilless substrate water status has been recognized as a promising approach for efficient greenhouse irrigation management. Identification of proper irrigation set points is crucial for optimal crop performance, both in terms of yield and quality, and optimal use of water resources. The objective of the present study was to deter...
