Single and dual crop coefficient methods are used in conjunction with grass reference evapotranspiration (ETo) to estimate actual crop evapotranspiration (ETc). However, the impact of soil surface residue cover on the accuracy of ETo estimated with these methods is not well understood... Read More
Determinants of conversion to drip irrigation systems by farmers: The case of the Mitidja plain in Algeria Over the last decade, Algeria has encouraged the adoption of water saving systems by providing subsidies to farmers through a national plan for agricultural development, with par... Read More
The development of site-specific water management systems for sprinkler irrigation will be a major factor in. future efforts to improve the various efficiencies of water-use and to support a sustainable irrigated environment. The challenge is to develop fully integrated management sys... Read More
The objective of this study was to characterize water application rate, water application pattern width, flow rate, water distribution uniformity and soil loss caused by nozzles of the Low Energy Precision Aplication (LEPA) type Quad-Spray emitter. The study was carried out at the Hyd... Read More
Climate change and recurrent drought in many of the world's dry places continue to inspire the search for economically attractive measures to conserve water. This study analyzes water conservation practices in irrigated agriculture in a sub-basin in North America's Rio Grande. A metho... Read More
Improving water productivity can make a sterling contribution to global food production and poverty alleviation. Groundwater has always been a critical resource for agriculture. Scientific understanding of water productivity can help address water scarcity concerns through more produc... Read More
Variations of the crop water stress index (CWSI) have been used to characterize plant water stress and schedule irrigations. Usually, this thermal-based stress index has been calculated from measurements taken once daily or over a short period of time, near solar noon or after and in ... Read More
An experiment was conducted to find out the effect of micro-irrigation and fertigation on water use efficiency, productivity, photosynthesis and sustainability of mustard crop during rabi seasons of 2009-10 and 2010-11. The treatments consisted of five irrigation systems in main plot ... Read More
The more sustainable use of scarce water resources is a policy goal in several countries. In this regard, current discussions on potential policy reforms in Switzerland revolve around the subsidization of water-saving irrigation technologies. Today, the share of drip irrigation system... Read More
Crop and technology choices in agriculture, which largely define the impact of agricultural production on the environment, should be considered in agricultural development planning. A life cycle assessment of the dominant crops produced in a Peruvian coastal valley was realized, in or... Read More
