Response of grain-filling rate and grain quality of mid-season indica rice to nitrogen application

open access: yesJournal of Integrative Agriculture, 2021
Nitrogen is one of the important factors for high yield of rice. Apart from high yield, high quality has become the current urgent demand for rice production. Grain-filling stage is crucial for rice yield and quality formation.

Drip fertigation technique with planting models strategies trigger grain filling, endogenous hormonal changes and maize productivity under semi-arid regions [PDF]

open access: yesFrontiers in Plant Science
Mulch drip fertigation strategies have been widely adopted to improve maize productivity in semi-arid regions. However, the impact of the mulch-based drip fertigation on endogenous hormone dynamics in crops and grain yield has not been fully elucidated ...

Proteomic identification of genes associated with maize grain-filling rate. [PDF]

open access: yesPLoS ONE, 2013
Grain filling during the linear phase contributes most of the dry matter accumulated in the maize kernel, which in turn determines the final grain yield. Endosperms and embryos of three elite maize hybrids (Zhengdan 958, Nongda 108, and Pioneer 335) were
