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...

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...

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,...

This report contains data on the origin, descriptive characteristics, agronomic performance, seed composition, and disease reaction. of over 2,800 accessions from the USDA Soybean Germplasm Collection in maturity groups 000 to IV. These accessions were introduced :into the United States from...

The boron element is unique among the essential elements in that a narrow range in concentration can mean the difference between plant deficiency and plant toxicity. Effect of potassium on boron toxicity reduction in wheat was evaluated at Agriculture Research Station located in Jahrom, Iran,...

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...

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...

Several photovoltaic applications, specially the water pumping systems, are installed to contribute in the socio–economic development in Algerian Sahara. About sixty pumps are installed in remote regions to supply water for drinking and irrigation. The centrifugal pumps present the...
