The installation and operation costs of drip irrigation systems can be reduced if the systems are designed using a lower uniformity. However, it remains unclear whether a lower system uniformity will result in a decreased crop yield and product quality in arid regions. Field experiments were...

Like many intensive vegetable production systems, the greenhouse-based system on the south-eastern (SE) Mediterranean coast of Spain is associated with considerable NO3− contamination of groundwater. Drip irrigation and sophisticated fertigation systems provide the technical capacity for...

Field experiments were conducted for 2 years to evaluate the use of the crop water stress index (CWSI) for irrigation scheduling of soybeans under a sub-humid climate of Bursa, Turkey. Additionally, statistical relationships between CWSI and seed yield, quality parameters, crop...

An experiment was conducted for two consecutive seasons to investigate the effect of water stress on seed yield and seed quality of onion (Allium cepa L.). Water stress was imposed on the plants at four stages of reproductive growth, namely, bolting, flowering, seed formation and seed maturation...

This study aims to evaluate the effects of elevated carbon dioxide (EC) on soybean growth in the water-deficient region of Huang-Huai-Hai Plain, China. A pot experiment involving two CO2 concentrations (ambient, 380.1±32.2μmolmol−1 and elevated, 740.6±45.4μmolmol−1) and two water levels...

The amount of plant available soil water is strongly influenced by soil type and rooting depth. This study was conducted to investigate the influence of limited plant available soil water on soybean (Glycine max (L.) Merr.) yield and seed composition. Six soybean cultivars were grown in 2007,...

The approach combines the basal crop coefficient (Kcb) derived from vegetation indices (VIs) with the daily soil water balance, as proposed in the FAO-56 paper, to estimate daily crop evapotranspiration (ETc) rates of orange trees. The reliability of the approach to detect water stress was also...

The fundamental principle of adequate irrigation management is to satisfy crop water requirements while optimizing agronomic profits with the lowest possible consumption of water. Based on this idea, new techniques have been incorporated into different irrigation scheduling approaches. Among...

The performance of two operational models for calculating daily actual evapotranspiration (ET) was presented in this study. Both models used only climatic variables collected by standard weather stations. The analysis was performed during 2000, 2001 and 2006 on three irrigated varieties of...

Lack of information on crop coefficient (kc) values of bed planted rice–wheat system in the Indo Gangetic Plains (IGP) of India has become a constraint for irrigation planning to improve the crop water productivity. In this paper, we estimated kc values from field water balance measured crop...
