Water and nitrogen availability limit crop productivity globally more than most other
environmental factors. Plant availability of macronutrients such as nitrate is, to a large extent …

This paper reviews the interactions between water and nitrogen from physiological,
agronomic, economic, breeding and modelling perspectives. Our primary focus is wheat; we …

We used a collection of Australian wheats released between 1958 and 2007 to probe for
time trends in evapotranspiration and nitrogen uptake, and the efficiencies in the use of …

An accurate estimation of crop evapotranspiration (ET c) is very useful for appropriate water
management; hence, an accurate and user-friendly model is needed to support related …

The impact of limited water and nitrogen (N) supply on maize productivity and on the
utilisation efficiency of key production resources (radiation, water and N) was quantified in …

Crop yield in dry environments can be improved with complementary approaches including
selecting for yield in the target environments, selecting for yield potential, and using indirect …

The nitrogen economy of the crop is a critical driver of biomass and grain production, and its
importance is reflected in a large, worldwide research effort to link nitrogen, growth and …

This paper is the second of a two-part series, with the first part describing the SIMDualKc
model, an irrigation scheduling simulation tool that employs the dual crop coefficient …

Interactions between nitrogen and water may vary between N 2 fixing species and species
that rely only mineral soil nitrogen. Here we compared above ground biomass accumulation …

The drive toward adoption of conservation agriculture to reduce costs and increase
production sustainably causes concern due to the potentially negative effects of increased …
