evaluating the performance of irrigation systems by providing the possibility of increasing irrigation efficiency in those systems is an important factor in the field of water resources management. in this study, the performance of three systems were evaluated, including linear move sprinkler irrigation systems in maize, sugar beet and alfalfa fields of magsal agro-industrial company which is l...
As an initial effort to understand the Asian irrigation systems dynamism and their robustness overtime, this paper examines two irrigation systems of Kok river system within Mekong river basin in Northern Thailand in the context of changing governance mechanisms and evolution of technological and market forces. Since the processes involved in first starting collective action are different than ...
In developing Asian countries, a major recent change in irrigation management is the rapid spread of private pumps and wells (modern irrigation systems). This process was accelerated by the introduction of the hydraulic drilling method in the 1980s and further by the development of the pump industry in China and India in the 1990s. The spread of modern systems is associated with the decline in ...
to evaluate the effects of fertilizing and deficit irrigation regimes on some chemical properties of soil and plant, an experiment was conducted during 2007 and 2008 growing seasons. experimental design was a split plot based on a randomized complete block design with four replications. the treatments consisted of three deficit irrigation regimes (main plots) and six soil fertilizing systems (s...
Countries are collaborating to make agriculture more efficient by combining new technologies improve its procedure. Improving irrigation efficiency in is thus critical for the survival of sustainable agricultural production. Smart methods can enhance efficiency, specially with introduction wireless communication systems, monitoring devices, and enhanced control techniques scheduling. The study ...
The spate irrigation is among the oldest and largest community managed irrigation systems in Pakistan and is providing livelihood to local communities through indigenously developed, maintained and managed techniques. The “Riwajaat-eAabpashi” (irrigation customs) codified in British rule are main guidelines for irrigation in lowland systems while upland systems are governed through locally know...
The lack of water resources in Iran has increased concern about water consumption in the country. The agricultural sector is known as the largest sector of water consumption, and saving in this sector will save significant water resources. One of the solutions for the optimal use of water resources is the use of modern irrigation methods with proper design and implementation. Therefore, the pur...
Irrigation in the Mediterranean is of vital importance for food security, employment and economic development. This study systematically assesses how climate change and increases in atmospheric CO2 concentrations may affect irrigation requirements in the Mediterranean region by 2080–2090. Future demographic change and technological improvements in irrigation systems are taken into account, as i...
Automatic irrigation systems usually conveniently protect landscape investment. While conventional irrigation systems are known to be inefficient, automated ones have the potential to optimize water usage. In fact, there is a new generation of irrigation systems that are smart in the sense that they monitor the weather, soil conditions, evaporation and plant water use, and automatically adjust ...
