Through the experimental data of a three year maize field test, this paper shows the calibration (year 2003) and validation (years 2001 and 2002) processes for the simulation of FAO-700 maize crop (Dracma and Brasco hybrids) under deficit irrigation conditions in Castilla-La Mancha (Spain) using...

This paper shows an adaptation of the typical meteorological year (TMY) method for irrigation schedule forecasting in combination with the optimized regulated deficit irrigation (ORDI) strategy to increase the water productivity of crops and their profitability. This methodology has been...

Under limited availability of irrigation water during the growing season, farmers must avoid a premature depletion of this resource that may lead to a sizeable decrease in yield. Four levels of net irrigation availability were considered for an onion (Allium cepa L.) crop cultivated in...

There are numerous models capable of simulating crop behavior under different water stress conditions. However, none of them takes into account the effect of irrigation water uniformity on yield. The model developed simulates the uniformity effect on yield and the repercussion on gross margin...

In both arid and semi-arid areas the use of saline water for irrigation is a common practice, even though it may cause a drop in crop yield and progressive soil salinization. In order to determine the most suitable irrigation strategy for higher yield, profitability, and soil salinity management...

The objective of this paper is to study evaporation and drift losses (EDLs) with two types of sprinklers: rotating spray plate sprinklers (RSPS) and fixed spray plate sprinklers (FSPS), both installed at two different heights (1 and 2.5m above the ground). A field test was carried out during...

The development of different tools to evaluate the performance of Water Users Associations (WUAs) is an important practice for improving water and energy management, together with other production costs. One of these tools is the Benchmarking technique, which is based on the comparison between...

Yield, cost, and revenue functions of potato (cv. Agria) were developed from field experiments in 2007–2008, which were designed to determine the response of tuber yield to no irrigation for two weeks at tuber bulking (TB) and tuber ripening (TR). Deficit-irrigated treatments were compared to...

The PRESUD tool was developed using MATLAB™ to identify the optimum microirrigation system design. The lowest cost was determined by calculating the annual water application cost per unit of irrigated area (CT). This is defined as the cost of one cubic meter of water applied to crops, and is...
