Involvement of miR169 in the nitrogen-starvation responses in Arabidopsis.
Recent studies have revealed that microRNAs (miRNAs) regulate plant adaptive responses to nutrient deprivation. However, the functional significance of miRNAs in adaptive responses to nitrogen (N)Expand

Using competitive and facilitative interactions in intercropping systems enhances crop productivity and nutrient-use efficiency
This paper reviews recent research on the processes involved in the yield advantage in wheat (Triticum aestivum L.)/maize (Zea mays L.), wheat/soybean [Glycine max (L.) Merr.], faba bean (Vicia fabaExpand

Improving intercropping: a synthesis of research in agronomy, plant physiology and ecology.
Intercropping is a farming practice involving two or more crop species, or genotypes, growing together and coexisting for a time. On the fringes of modern intensive agriculture, intercropping isExpand

Strategies for overcoming low agronomic nitrogen use efficiency in irrigated rice systems in China
Abstract Irrigated rice in China accounts for nearly 30% of global rice production and about 7% of global nitrogen (N) consumption. The low agronomic N use efficiency (AEN, kg grain yield increaseExpand

Nitrogen Fertilization, Soil Nitrate Accumulation, and Policy Recommendations in Several Agricultural Regions of China
Abstract Excessive nitrogen (N) fertilization and decreasing N recovery rates by crops have caused dramatic increases in non-point source pollution from agriculture in China. The rate of NExpand
