Abstract Quantifying reasonable crop yield gaps and determining potential regions for yield improvement can facilitate regional plant structure adjustment and promote crop production. The current study attempted to evaluate the yield gap in a region at multi-scales through model simulation and farmer investigation. Taking the winter wheat yield gap in the Huang-Huai-Hai farming region (HFR) for the case study, 241 farmers’ fields in four typical high-yield demonstration areas were surveyed to… Expand


Effect of nitrogen and water deficit type on the yield gap between the potential and attainable wheat yield
Water deficit and N fertilizer are the two primary limiting factors for wheat yield in the North China plain, the most important winter wheat (Triticum aestivum L.) production area in China.Expand
Quantifying the yield gap in wheat–maize cropping systems of the Hebei Plain, China
Abstract Wheat–maize double cropping is the most important cropping system on the Hebei Plain and is one of the most important cropping systems in China. In a scenario of greater food demand, andExpand
Strategies for narrowing the maize yield gap of household farms through precision fertigation under irrigated conditions using CERES-Maize model.
The integrative method lays a foundation for exploring the specific factors constraining crop yield gaps at the field scale and for developing strategies for rapid site-specific N management. Expand
Rational trade-offs between yield increase and fertilizer inputs are essential for sustainable intensification: A case study in wheat-maize cropping systems in China.
It is found that the yield gaps among the different farmers were still large, and most farmers applied excessive amounts of N while obtaining unsatisfactory yields due to poor fertilizer management techniques, so sustainable intensification of agricultural production with lower environmental costs will be feasible in China.

Spatio-temporal patterns of winter wheat yield potential and yield gap during the past three decades in North China
Abstract To develop strategies for sustainable intensification of agricultural production, it is necessary to obtain precise and spatially explicit knowledge of crop potential and yield gap at aExpand
Winter Wheat Yield Gaps and Patterns in China
Wheat (Triticum aestivum L.) yield stagnation has been reported in some regions of the world. China is the largest producer of wheat across the globe, but the pattern of its wheat yield stagnationExpand
Yield and nutrient gap analysis for potato in northwest China
Abstract Analysis of the potato yield gap and the corresponding nutrient gap can help in devising strategies and measurements to increase productivity for closing the gaps through improved practices.Expand
Assessment of maize yield gap and major determinant factors between smallholder farmers in the Dedza district of Malawi
Abstract This study explored the effect of soil nutrient status, agronomic practices and socio-economic factors on maize yield attained by smallholder farmers in the Dedza District of Malawi. ResultsExpand
Factors Affecting Nitrogen Use Efficiency and Grain Yield of Summer Maize on Smallholder Farms in the North China Plain
The summer maize yields and partial factor productivity of nitrogen (N) fertilizer (PFPN, grain yield per unit N fertilizer) on smallholder farms in China are low, and differ between farms due toExpand
Spatial variation of attainable yield and fertilizer requirements for maize at the regional scale in China
Abstract Understanding attainable yield, soil nutrient supply capacity and fertilizer requirements in current intensive maize (Zea mays L.) production at regional and national scales in China isExpand
