The phenological development of cereal crops from emergence through flowering to maturity is largely controlled by temperature, but also affected by day length and potential physiological stresses. Responses may vary between species and varieties. Climate change will affect the timing of cereal crop development, but exact changes will also depend on changes in varieties as affected by plant bre...
The combination of organic manure and inorganic fertilizer plays a role in increasing crop yield nutrient efficiency, but such effectiveness varies with crop, soil, management, climate. Here, 6-year field experiment was conducted to evaluate the effects substituting on yield, grain protein content, nitrogen phosphorus efficiency under winter wheat-summer maize cropping system Anthrosol. Five tr...
Tillage practices can redistribute the soil profiles, and thus affects soil organic carbon (SOC), and its storage. The stratification ratio (SR) can be an indicator of soil quality. This study was conducted to determine tillage effects on the profile distribution of certain soil properties in winter wheat (Triticum aestivum L.) and summer maize (Zea mays L.) systems in the North China Plain (NC...
Earth's water resources are critical for supporting livelihoods and food security but being increasingly overexploited to support global agriculture. Diversifying cropping systems could potentially resolve unsustainable use trade-offs with other aspects of sustainability have not yet been assessed. We performed a detailed analysis 31 different field crop rotations conducted during 1990–2019 in ...
Wheat, cotton, and peanut were arranged in three cropping sequences to determine the effects of fenamiphos (6.7 kg a.i./ha) and cropping sequence on nematode population densities and crop yields under conservation tillage and irrigation for 6 years. The cropping sequences included a wheat winter cover crop each year and summer crops of cotton every year, peanut every year, or cotton rotated eve...
Fraction of Photosynthetically Active Radiation (FPAR) is a critical parameter in land surface energy balance and climate modeling. Several global FPAR products are available, but these still require considerable assessment and validation due to low spatial resolution. Three major FPAR products that have covered China and provided continuous time series data—MODIS, MERIS and GEOV1—were assessed...
The management of dairy production systems based on rotational grazing and maize-concentrate feeding requires a complex lookahead decision making procedure to elaborate a seasonal strategy that is sufficiently robust to uncertainty. In this paper, the problem is characterized rather precisely as finding for the late winter to early summer period an appropriate combination of commitments concern...
The East Asian monsoon (EAM) and the El Niño Southern Oscillation (ENSO) determine climate variability over much of East Asia, affecting vulnerable grain markets and food security in China. In this study, we investigated the variability of climate and of agricultural production in China in association with the East Asian summer monsoon (EASM) and ENSO. Data from China showed that a strong EASM ...
