Due to the scarcity of water resources in Northwest China, the use of deficit irrigation scheduling is beneficial for sustainable agricultural development. Therefore, a 2-year field experiment was performed to investigate the effects of regulated deficit irrigation (RDI) on the yield and water productivity (WP) of drip-irrigated chili pepper plants in a typical arid environment of Northwest China. The results indicate that RDI strategies reduced actual crop evapotranspiration by 2–27%. Crop coef...

Hetao Irrigation District (HID) is characterized by less rainfall and high evaporative, but it is a main grain production region in China. Increasing water use efficiency is an appropriate way to fulfill the sustainable agriculture development because the allocated water for HID will be reduced in the future. In this study six irrigation treatments with irrigation amounts being the 20, 40, 60, 80, 100, and 120% of crop water requirement (ETc) were carried out for maize crop (Zea mays L.) in the ...

Water shortage and high irrigation rate has increased the need for appropriate irrigation scheduling to improve agricultural water use efficiency for food security in Northwest China. A two-year field experiment was carried out to investigate the response of melon (Cucumis melo L.) yield, quality and water productivity (WP) to various soil moisture levels with controlled furrow irrigation in the arid oasis region of Gansu Province. Soil water content (SWC) with values of 55% and 65% FC (field ca...

Excess application of nitrogen has proved to be one of the detrimental impact factors on soil and groundwater quality in the North China Plain (NCP). A 4-year (from October 2008 to September 2012) field experiment was carried out to investigate the impact of N application rate on NO3–N dynamics in soils, its leaching pattern, and movement in deep soils under different nitrogen (N) application rates in a sprinkler irrigated winter wheat (Triticum aestivum L.)- summer maize (Zea mays L.) field in ...

Winter wheat production in the North China Plain (NCP) relies mainly on irrigation. To assess the effect irrigation management practices on crop production, the HYDRUS-1D model was modified by incorporating the crop growth module adopted from the EPIC model. The modified HYDRUS-1D model was calibrated and validated by using data collected from 2006/2007 and 2007/2008 winter wheat growing seasons in Beijing area. The predicted values for soil water content, soil nitrate concentration, crop growth...

Stemflow is important for analyzing soil water dynamics and plant growth in regions with limited rainfall. The objective of this study was to determine the amount of stemflow in relation to plant and rainfall properties. In this study, stemflow was measured using a high water adsorption sheet method during the period of maize plant height growth approximately from 100cm to 230cm when the leaf area index increases from 1.0 to 4.5. There were 28 rainfall events with rainfall amounts for each event...

To improve irrigation water-use efficiency, plant transpiration and soil evaporation in a maize (Zea mays L.) field in the Bulang sub-catchment of the Hailiutu River catchment in Northwest China were determined using in situ measurements. Crop transpiration (Tp) rates from Jul 15 to Oct 1, 2011 were measured with sap flow sensors, and soil evaporation (Ep) rates were measured with micro-lysimeters under an absence of water deficit. The two rates together gave the total evapotranspiration (ETc) o...

AbstractIn the present study, an attempt has been made to study the reference evapotranspiration (ETo) change and the sensitivity of estimated ETo to each climatic variable in a semi-humid and semi-arid region of Beijing in the north China using data from 1951 to 2010. Results show that in the past 60 years, yearly ETo was increasing with a rate of 19.5 mm per decade, and seasonal total ETo in wheat and corn seasons were increasing with rates of 13.1 and 5.3 mm per decade, respectively. Sensitiv...
