Improving crop productivity and resource use efficiency to ensure food security and environmental quality in China.
In recent years, agricultural growth in China has accelerated remarkably, but most of this growth has been driven by increased yield per unit area rather than by expansion of the cultivated area. Looking towards 2030, to meet the demand for grain and to feed a growing population on the available arable land, it is suggested that annual crop production should be increased to around 580 Mt and th...

متن کاملInternational Productivity Comparisons at the Industry Level
As more and more industries experience the globalisation of business activities, measuring productivity performance has become an area of concern for companies and policy makers in Europe, the United States and Japan. This paper provides a non-technical synthesis of the productivity measurement methods used in a series of comparative industry studies. Such studies try to reach beyond standard a...
متن کاملStylosanthes guianensis as a short-term fallow crop for improving upland rice productivity in northern Laos
In northern Laos, rapid population growth and government policies to reduce the area under slash-and-burn systems have resulted in increased cropping intensity, which has increased weed pressure and reduced yields of upland rice. Promising alternative cropping systems include the use of weed-suppressing and multi-purpose legumes as short-term fallow crops. In this study, Stylosanthes guianensis...
متن کاملImproving crop salt tolerance.
Salinity is an ever-present threat to crop yields, especially in countries where irrigation is an essential aid to agriculture. Although the tolerance of saline conditions by plants is variable, crop species are generally intolerant of one-third of the concentration of salts found in seawater. Attempts to improve the salt tolerance of crops through conventional breeding programmes have met with...
