The availability of carbon (C) from high levels of atmospheric carbon dioxide (CO2) and
anthropogenic release of nitrogen (N) is increasing, but these increases are not paralleled …

Background Limitation of plant productivity by phosphorus (P) supply is widespread and will
probably increase in the future. Relatively large amounts of P fertilizer are applied to sustain …

Nutrient deficiencies are considered major constraints to rice production in sub-Saharan
Africa (SSA), but a systematic, continent-wide analysis of these constraints is lacking. The …

Enhancing rice yield in upland rice systems through genetic improvement remains a major
challenge in the tropics. This review aims to provide the trends on upland rice cultivation …

In rice, genotypic differences in phosphorus (P) uptake from P-deficient soils are generally
proportional to differences in root biomass or surface area (RSA). It is not known to what …

This work performs a review of the relevant aspects of agronomic dynamics of phosphorus
(P) in the soil–plant relationship as a community (crop ecophysiology), the effect of …

Improving nutrient uptake is an objective in crop breeding, especially in tropical areas where
infertile soils dominate and farmers may not have the resources to improve soil fertility …

Upland rice (Oryza sativa) is adapted to strongly phosphorus (P) sorbing soils. The
mechanisms underlying P acquisition, however, are not well understood, and models …

Phosphorus (P) efficiency (PE), which comprises phosphorus uptake (PupE) and utilization
efficiency (PutE), is considered as one of the most important factors for crop yield. In the …

Phosphorus use efficiency (PUE) can be improved through cultivation techniques and
breeding. However, little is known about rice (Oryza sativa L.) agronomic and physiological …
