hydraulic evaluation of low pressure drip irrigation systems using mathematical modelling and experimental data
in the present study, hydraulic properties of low pressure drip irrigation systems in lateral pipes were evaluated by mathematical model with the aid of experimental data resulting from testing of tubes available in iran. in this regard, emitters discharge were measured in different initial heads from 0.45 to 1.8 m for laterals with outside diameter of 32 mm with different lengths of 89, 60, 30...
متن کاملDesign Considerations for Subsurface Drip Irrigation (SDI) Systems
Gary A. Clark Research Irrigation Engineer Quick Facts Subsurface drip irrigation (SDI) is a low-pressure irrigation system that uses polyethylene driplines that are permanently buried below the soil surface. Water drips to the surrounding soil through built-in emitters (specialized small openings). SDI places water directly into the root zone of the crop. It may improve yield due to high appli...
متن کاملEffects of salinity and irrigation water management on soil and tomato in drip irrigation
In this research, the effects of irrigation with saline and fresh water through drip irrigation method and using two irrigation management strategies: M1, M2 (M1 is irrigation with fresh water in alternative with saline water, M2 is saline water in first half time of each irrigation event and fresh water in the second half), on the yield, water productivity (WP), soil salinity, plant height...
متن کاملOptimize Above–ground Drip Irrigation Systems for Small Areas
Drip irrigation systems offer the potential for efficient irrigation of high value crops and have proven feasible from engineering and agronomic standpoints in the northern Great Plains. However, little information is available in this region regarding the optimum design and economics of these systems. The objective of this study was to develop a computerized model for design and economic optim...
متن کاملApplication of alternative fumigants through drip irrigation systems.
ABSTRACT Strawberry fields in California (9,500 ha annually) are pre-plant fumigated with methyl bromide and chloropicrin to prevent serious soil pest and disease problems. Although soil fumigation with methyl bromide has ensured stability of strawberry production, its use is being discontinued because of its effect on stratospheric ozone. The likely short-term alternatives such as 1,3-dichloro...
