Abstract:
... Rice grain yield is determined by three major “visible” morphological traits: grain weight, grain number per panicle, and effective tiller number, which are affected by a series of “invisible” physiological factors including nutrient use efficiency and photosynthetic efficiency. In the past few decades, substantial progress has been made on elucidating the molecular mechanisms underlying grain yie ...

Abstract:
... AIMS: Harsh edaphic environments harbor species with different soil affinities. Plant’s responses to specific edaphic constraints may be compromised against responses to prevalent stresses shared with other semi-arid environments. We expect that species with high edaphic affinity may show traits to overcome harsh soil properties, while species with low affinity may respond to environmental constra ...

BACKGROUND: For more than a century, crop N nutrition research has primarily focused on inorganic N (IN) dynamics, building the traditional model that agricultural plants predominantly take up N in the form of NO₃⁻ and NH₄⁺. However, results reported in the ecological and agricultural literature suggest that the traditional model of plant N nutrition is oversimplified. SCOPE: We examine the role o ...

In contrast, organic farming (OF) is highly dependent on closed nutrient cycles, biological N fixation and crop rotations. However, both systems need to minimise N balances and maximise nitrogen-use efficiency (NU ...
