Soil water stress ranges: water use efficiency and Chinese cabbage production in protected cultivation

RICE CULTURE Effects of Water-Saving Rice Cultivation Methods on Yield, Water Use, and Water-Use Efficiency

Water available for irrigation is declining in many rice-growing regions around the world. Global populations continue to rise increasing crop production demand. Rice production systems must face the dilemma of maintaining or increasing yields with less water available to irrigate. Alternate wetting and drying (AWD) has shown to be an effective tool for water conservation in irrigated rice syst...

Soil water regime and water concervation efficiency in a non-irrigated semi-arid environment

Maize response to water, salinity and nitrogen levels: yield-water relation, water-use efficiency and water uptake reduction function

Water, salinity and nitrogen are the major factors affecting maize production in arid and semi-arid areas. The objectives of this study were to investigate the effects of different water, salinity and nitrogen levels on yield-water relationships, water use, water productivity (WP), water use efficiency (WUE) and water uptake reduction function by maize hybrid SC-704 in a semi-arid area and ...

Impacts of Drought Stress and Planting Methods on Sweet Corn Yield and Water Use Efficiency

Abstract Seasonal drought is the most important factor to limit the production of maize in the world. Using a split plot design, a two year field experiment was conducted to determine the effect of limited irrigation regime on yield, yield components and water use efficiency of sweet corn (Zea mays var. saccharata). Responses of three sweet corn varieties KSC403, Merit and Obsession to three di...

WATER USE EFFICIENCY Deficit irrigation in grapevine improves water-use efficiency while controlling vigour and production quality

Grapevine irrigation is becoming an important practice to guarantee wine quality or even plant survival in regions affected by seasonal drought. Nevertheless, irrigation has to be controlled to optimise source to sink balance and avoid excessive vigour. The results we present here in two grapevine varieties (Moscatel and Castelão) during 3 years, indicate that we can decrease the amount of wate...
