In this paper, an efficient irrigation system is proposed based on computing evapotranspiration (ET) and the required irrigation quantity using fuzzy inference methodology. The aim of this system is to schedule irrigation according to the particular requirements of a crop and to the change in various climatological parameters and other factors. This is to avoid overor under-watering which signi...
Artificial rainwater harvesting system (ARHS) is a new way to increase water supply in semi-arid area, and has developed rapidly recent years in northwestern China. Not only it used in domestic supply, but also in agricultural as supply irrigation. More than 2 million water cellars have been built in Loess Plateau of China. In this paper, based on 5 years’ related experiments, field engineering...
with population growing throughout the world, it is necessary to optimize water use,especially in agricultural lands. in order to conduct technical and economical evaluation ofdrip and furrow irrigation methods under deficit irrigation of cotton, a field experiment wascarried out during 2010 growing season at experimental farm of orzoueyeh agricultural andnatural resources research center in ke...
for continues production if field crops in arid and semi arid regions of the world, such as iran, beside of using of drought resistant varieties, water management must also be considered. in this context, the use of tape drip irrigation system could reduce the amount of irrigation water consumption. this study, was conducted to determine the best sowing pattern of sugar beet under type drip irr...
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...
The concept of resilience is widely promoted as a promising notion to guide new approaches to ecosystem and resource management that try to enhance a system's capacity to cope with change. A variety of mechanisms of resilience specific for different systems have been proposed. In the context of resource management those include but are not limited to the diversity of response options and flexib...
Water availability is the key factor determining maize yields in NE Spain. Irrigation is needed to obtain economic yields but it is costly and water supply is sometimes insufficient. The aim of this research was to test a simple simulation model for evaluating different irrigation strategies, especially under water-limited conditions. The LINTUL model was adapted and parameterized using experim...
