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. On-farm experiments conducted in the main potato production areas of northwest China were used to determine attainable yield. Official statistical data were used to determine the actual on-farm yield. Yield gap was the difference between attainable yield and actual on-farm yield. Nutrient gap was… Expand
Assessing the potato yield gap in the Peruvian Central Andes
Abstract The Peruvian Central Andes is a highly important area for potato production. Assessing the potato yield gap and the potential yield is an essential step towards sustainable cropExpand
Multi-scale assessment of winter wheat yield gaps with an integrated evaluation framework in the Huang-Huai-Hai farming region in China
A multi-scale yield gap evaluation framework integrated with typical field survey and crop model analysis could provide valuable information for narrowing the yield gap. Expand


Quantification of yield gap and nutrient use efficiency of irrigated rice in China
Abstract Analyzing attainable yield (YA), yield gap (YG), and nutrient use efficiency (NUE) will help develop and inform agricultural policies and strategies to increase grain yield. Data from aExpand
Yield Gap, Indigenous Nutrient Supply and Nutrient Use Efficiency for Maize in China
There would be considerable potential to further improve yield and nutrient use efficiency in China, and will help develop and inform agricultural policies and strategies, while some management measures such as soil, plant and nutrient are necessary and integrate with advanced knowledge and technologies.

Understanding production potentials and yield gaps in intensive maize production in China
Abstract Understanding yield potentials and exploitable gaps in current intensive maize ( Zea mays L.) production is essential in order to increase grain yields to meet future food requirements amidExpand
Yield Gaps and Ecological Footprints of Potato Production Systems in Chile
In Chile, potatoes are grown in a wide range of ecological zones and levels of technology resulting in wide ranges of crop management and yields. The aim of the present study was to assess yieldExpand
Yield gap analysis and resource footprints of Irish potato production systems in Zimbabwe
Irish potato is the third most important carbohydrate food crop in Zimbabwe after maize and wheat. In 2012, the Government of Zimbabwe declared it a strategic national food security crop. In thisExpand
Winter wheat yield potentials and yield gaps in the North China Plain
The North China Plain (NCP) is the most important wheat production area in China, producing about two-thirds of China's total wheat output. To meet the associated increase in China's food demand withExpand
Fertilizer Use and Wheat Yield in Central and Eastern European Countries from 1986 to 2005 and Its Implication for Developing Sustainable Fertilizer Management Practices
Economic and political challenges impact agricultural practices, production efficiency, and crop yields. We hypothesize that increased conversion efficiency of fertilizer to crop yield resulted fromExpand
Demonstrating a link between nutrient use and water management to improve crop yields and nutrient use efficiency in arid Northwest China.
China’s Northwest belongs to an arid and semiarid region with an annual rainfall of 200 to 400 mm or less, where potential evaporation often exceeds precipitation. Lack of moisture in the soil makesExpand
Closing yield gaps through nutrient and water management
A global-scale assessment of intensification prospects from closing ‘yield gaps’, the spatial patterns of agricultural management practices and yield limitation, and the management changes that may be necessary to achieve increased yields finds that global yield variability is heavily controlled by fertilizer use, irrigation and climate.
