the forefront of institutional reform in the water sector. It was also the first to significantly raise irrigation service fee on public irrigation systems. The Maharashtra State Water Policy of 2003 was a landmark of sorts. In 2005, the state passed two important pieces of legislation: one, Maharashtra Management of Irrigation Systems by Farmers (MMISF) Act, and two, Maharashtra Water Resource...
[1] In this study, two parameterizations for different irrigation techniques have been implemented in a regional climate model. These implementations allow for a comparative study of water use and land–atmosphere interactions associated with traditional flood irrigation—a widespread but highly water-inefficient practice—and water-conserving drip irrigation. Both parameterizations yield realisti...
Application of the modern irrigation systems such as T-Tape irrigation system is one of the ways to achieve aptimal irrigation The present study deals with the effect of surface and subsurface drip irrigation systems on the cotton yield For this purpose, a field experiment was conducted in the Agricultural and Natural Resource Research Institute of Orzoueyeh, located in the Kerman province. The...
This paper presents configuration of knowledge to solve irrigation scheduling problem in agriculture domain and a general approach for configuration management knowledge throughout the integration between operations research and expert systems approach. This work has established new configuration structure for an Irrigation Scheduling Configuration System suitable for CommonKADS Layers to produ...
this research was designed to evaluate and compare the applicability of two different types of irrigation including traditionally (surface irrigation) and simple sub-surface drip irrigation (using pricked-pipe covered with plastic cloth). two plots containing 39 pistachio trees with 720 m2 area were selected in rafsanjan, iran. both plots were irrigated using exactly the same quantity and quali...
(eds M.C.S. Wopereis et al.) 265 supply sufficient water for drinking water and irrigation. Exceptions are the Volta River basin in West Africa and the Orange and Limpopo River basins in Southern Africa, where population density and large-scale irrigation systems put great strains on water resources availability (Ravenga et al., 2000). There is large untapped irrigation potential in SSA. IFPRI ...
The conventional irrigation systems tend to waste irrigation water by not considering the upcoming precipitation. The precipitation in India being erratic in nature calls for the use of efficient forecasting methods. This paper proposes a design of irrigation system that employs a weather forecasting algorithm to calculate the water requirement and control irrigation based on soil moisture for ...
In past couple of decades, there is immediate growth in field of agricultural technology. Utilization of proper method of irrigation by drip is very reasonable and proficient. A various drip irrigation methods have been proposed, but they have been found to be very luxurious and dense to use. The farmer has to maintain watch on irrigation schedule in the conventional drip irrigation system, whi...

High latitude agriculture is rainfed. Climate change could, however, increase water deficiency and initiate a call for development of irrigation systems as a part of field water management systems. This study aimed to develop a basic understanding about the current state of irrigation potential according to region by monitoring proximity of fields to waterways and characterizing their general c...
