Realizing the internal flow visualization inside the drip irrigation emitter is the basis of optimizing the labyrinth path structure and promoting its anti-clogging capability. The Computational FluidDynamics (CFD)method has become an effective approach to research the water movement in the labyrinth path of the drip irrigation emitter. In this paper, the standard k-ε model and the Large Eddy S...

Livelihoods of the rural people of Ethiopia depend on agriculture. However, erratic nature of rain and prevalence of drought in the country make agricultural production a challenge. To counter this problem, use of the available water resource for irrigation development is the most promising option. Ketar small scale irrigation scheme is found in Ketar-Genet Peasant association, Tiyo District, A...

In surface irrigation, the soil serves as a medium for infiltration and conveying water from upstream to the downstream end of a field. In this study, infiltration properties of the Sibaya (Si) soil series (Glenrosa in the South African soil classification system) were determined by a volume balance method using a two-point approach technique. The purpose of the study was to examine the effect ...

EXTENDED ABSTRACT The aim of this study was the optimization of pressurized irrigation networks using conventional and fuzzy numbers. In particular, the method of dynamic programming was utilized, whose implementation required the development of a program in Visual Fortran. The program was first applied using conventional numbers in three irrigation networks in the area of Kavasila (the former ...

* Department of Soil Science, Punjab Agricultural University, Ludhiana 141 004 Abstract: Different irrigation methods and regimes affect maize (Zea Mays L.) growth differently. The field experiment was conducted to study the interactive effect of three irrigation methods and three irrigation regimes on maize growth under sandy loam soil at the Research Farm of Department of Soil Science, Punjab...

Automatic irrigation scheduling has been demonstrated using wired sensors and sensor network systems with subsurface drip and moving irrigation systems. However, there are limited studies that report on crop yield and water use efficiency resulting from the use of wireless networks to automatically schedule and control irrigations. In this 2011 study, a multinode wireless sensor network (WSN) s...

to evaluate the effect of water, tape drip and furrow irrigation methods on the performance components and features of agria cultivar potato, an experiment was carried out in the agriculture faculty of kermanshah. repeated three times, this study was carried out in the form of full random blocks with the main factor of different amounts of irrigation water in three levels (50, 75, and100 percen...
