Furrow Irrigation Management and Design Criteria Using Efficiency Parameters and Simulation Models

Abstract

This study analyzes the relationship between the variables of furrow irrigation and the irrigation performance parameters, crop yield, and deep percolation as a basis for furrow irrigation design and management. Application efficiency (AE), requirement efficiency (RE), requirement distribution efficiency (RDE), total distribution efficiency (TDE), and furrow irrigation management, operation, and design variables (inflow discharge, furrow length, and irrigation cutoff time) were correlated. The relationship between performance irrigation parameters and relative yield was also examined. In addition, environmental aspects related to leaching and runoff were also presented for each of the parameters. Study results indicate that increasing the length of the furrow reduces RE, RDE, and TDE values. However, an increase in inflow discharge and cutoff time increases efficiency. In contrast, an increase in furrow length increases AE while an increase in inflow discharge and cutoff time reduces it. Unlike AE, RE, RDE, and TDE parameters are well-correlated with relative yield. TDE and AE are recommended parameters for the design, management, and operation of furrow irrigation systems, in order to establish good irrigation practices, and to prevent contamination.

Comparing Water Performance by Two Different Surface Irrigation Methods

“…Therefore there is an evidence to encourage the IDI irrigation method. Water use efficiency, irrigation water use efficiency, and distribution uniformity are the performance irrigation parameters that seem to be correlated with furrow irrigation variables (water table, inflow discharge, volume applied and time of irrigation) it was observed by Holzapfel et al, (2010). They are also the parameters that thus could have a relationship between crop productivity and production and the irrigation variables.…”

Reuse and Recycling of Livestock and Municipal Wastewater in Chilean Agriculture: A Preliminary Assessment

“…Indeed, agricultural census data (1997 and 2007) show stagnation of both the under irrigation area and water consumption in agriculture [9]. The increase in agricultural productivity in recent years has been due to the research/conversion of conventional irrigation systems (gravitational and superficial) by pressurized irrigation (sprinkler and micro-irrigation), as well as the increased efficiency of furrow irrigation [22,23]. However, the dynamic growth of this activity requires looking for sustainable alternatives for the future.…”

“…According to the previous data, Chile has matured regarding its coverage of municipal and livestock WWPTs. However, there are no government policies (only general guidelines) that adequately strengthen wastewater recycling [23,66]. These new policies must be based on the circular-economy concept to establish a more sustainable model in wastewater management [16].…”

Optimum Rate of Blended Fertilizer and Urea Determination for Potato Production under Irrigation Condition in Holetta Research Center, West Showa, Ethiopia

“…When irrigation is required there are many available methods and management strategies. The selection of the method and approach depends on factors such as water availability, crop type, soil characteristics, land topography and associated cost [10]. Furrow irrigation is one of the most frequently used surface irrigation methods in the world [11].…”
