Linking Aboveground Traits to Root Traits and Local Environment: Implications of the Plant Economics Spectrum. [PDF]

open access: yes, 2019
The plant economics spectrum proposes that ecological traits are functionally coordinated and adapt along environmental gradients. However, empirical evidence is mixed about whether aboveground and root traits are consistently linked and which ...

Bidirectionally Thermochromic Nanocolloid System for on‐Demand Optical Switching and Agricultural Energy Management

open access: yesAdvanced Science, EarlyView.
A bidirectionally thermochromic nanocolloid system is developed for facility agriculture. The bidirectional and wide‐temperature response dynamically modulates light radiation, stabilizing the indoor climate, improving supplemental lighting efficiency, and accelerating plant photosynthesis.

Biomimetic Adaptive Hydrothermal Balance Fabric‐Based Dual‐Interface Solar Evaporator for Efficient and Stable Desalination

open access: yesAdvanced Science, EarlyView.
This study combines the biological structure of octopuses with the “3D structure” of spacer fabrics to fabricate a dual‐interface solar evaporator with adaptive hydrothermal balance. Water adaptation is achieved through the differentiated design of the upper and lower layers, and dynamic hydrothermal balance is realized by dynamically regulating the ...

Examining the Impact of Row Planting on Labor Use for Sustainable Food Production Among Maize Farmers in Rural Ghana

open access: yesAgribusiness, EarlyView.
ABSTRACT Smallholder farmers are reverting to traditional production methods due to the high opportunity costs and unintended consequences of new technologies. This study focuses on row planting technology, which is labor‐intensive and slow without mechanized operations.

Soybean seed germination and initial seedling growth as affected by seed size [PDF]

open access: yesJournal on Processing and Energy in Agriculture, 2013
Soybean seed size can have a major effect on the quality of seeds. Beside the effect that seed size has on 1000-grain weight, it can also affect other seed quality parameters. Some authors suggest it can be expected that larger seeds have better quality.
