Mechanisms of light energy harvesting in dendrimers and hyperbranched polymers [PDF]

, 2011
Since their earliest synthesis, much interest has arisen in the use of dendritic and structurally allied forms of polymer for light energy harvesting, especially as organic adjuncts for solar energy devices.

Nitrogen/potassium interactions increase rice yield by improving canopy performance

Food and Energy Security, 2021
The interactions between nitrogen (N) and potassium (K) are important determinants of rice yield, but the mechanisms involved remain poorly understood. For example, N/K interactions may influence light utilization and N distribution in the canopy.

Ecosystem‐scale biogeochemical fluxes from three bioenergy crop candidates: How energy sorghum compares to maize and miscanthus

GCB Bioenergy, 2021
Perennial crops have been the focus of bioenergy research and development for their sustainability benefits associated with high soil carbon (C) and reduced nitrogen (N) requirements.

Ridge-furrow planting with black film mulching increases rainfed summer maize production by improving resources utilization on the Loess Plateau of China

Agricultural Water Management, 2023
Soil mulching has been widely used to improve crop productivity around the world, but how various mulching practices affect soil hydrothermal conditions, water-temperature-radiation utilization and finally grain yield of rainfed maize has been poorly ...

Trade‐off between light interception efficiency and light use efficiency: implications for species coexistence in one‐sided light competition [PDF]

Journal of Ecology, 2013
Summary Taller plant species can pre‐empt solar energy and suppress growth of subordinate species in vegetation stands, which is described through one‐sided competition. Yet, in much of the world's vegetation species of different statures coexist. This study aims to clarify the mechanisms underlying this apparent paradox.

Supplemental LED Increases Tomato Yield in Mediterranean Semi-Closed Greenhouse

Agronomy, 2020
Supplemental light (SL) is a technique used to increase horticulture yield, especially in northern countries, where the Daily Light Integral (DLI) is a limiting factor during fall and winter, and which could also be used to obtain higher tomato yield at ...

Morphological and Physiological Properties of Greenhouse-Grown Cucumber Seedlings as Influenced by Supplementary Light-Emitting Diodes with Same Daily Light Integral

Horticulturae, 2021
Insufficient light in autumn–winter may prolong the production periods and reduce the quality of plug seedlings grown in greenhouses. Additionally, there is no optimal protocol for supplementary light strategies when providing the same amount of light ...

Remote sensing of ecosystem light use efficiency with MODIS-based PRI [PDF]

Biogeosciences, 2011
Several studies sustained the possibility that a photochemical reflectance index (PRI) directly obtained from satellite data can be used as a proxy for ecosystem light use efficiency (LUE) in diagnostic models of gross primary productivity.

Estimation of Dry Matter Production and Yield Prediction in Greenhouse Cucumber without Destructive Measurements

Agriculture, 2021
In this study, we aimed to estimate dry matter (DM) production and fresh fruit yield in “Fresco-dash” (FD) and “Project X” (PX) cucumber cultivars using an empirical model developed for tomatoes.
