Radiation‐Use Efficiency in Summer Rape
Agronomy Journal, 1995AbstractThe radiation‐use efficiency (RUE) is a parameter that represents a crop canopy's ability to convert intercepted solar energy to dry matter. The RUE is used in simulation models and can vary with crop type and environment. The objective was to examine the effects of varying row width and seeding rate on the amount of intercepted ...

Publisher Summary This chapter reviews the various aspects of radiation use efficiency (RUE). Topics that are covered include theoretical analyses, experimental determination and measures, and sources of variability. Crop growth rate (dm/dt) could be readily estimated from successive harvests through the growing season.

Radiation Interception, Radiation Use Efficiency and Crop Productivity
2016Photosynthesis is the set of processes whereby radiant energy is converted and stored as chemical energy in most plants, algae and cyanobacteria. This process depends on radiation, temperature and CO2 concentration. The maximum efficiency of the process is 6 % but it is usually well below.

Use of tile overlays to reduce the radiation efficiency of radiating surfaces
The Journal of the Acoustical Society of America, 2002An intriguing possibility for reducing the radiation efficiency of a structure is to overlay its radiating surfaces with a contiguous set of low mass tiles. Experimental results show that significant reductions in sound power are possible depending on number of tiles, their geometry, attachment methods, mass, stiffness, and the amount of shear damping ...

Radiation interception, radiation use efficiency and growth of barley cultivars
Australian Journal of Agricultural Research, 1993Dry matter production and utilization of photosynthetically active radiation (PAR) was studied for barley (Hordeurn vulgare L.) in the field at Hermitage Research Station, Qld. In 1990, four cultivars (Gilbert, Tallon, Grimmett, Skiff) were sown at three times and grown with non-limiting soil moisture. In 1991, soil moisture limitations were imposed on

Night Temperature Affects Radiation‐Use Efficiency in Peanut
Crop Science, 1992Three peanut (Arachis hypogaea L.) cultivars were grown under optimal field conditions in two environments in subtropical Australia contrasting primarily in night temperature. Mean minimum temperatures during the growing season were 16.7 °C (Kingaroy, cool) and 20.1 °C (Bundaberg, warm).

Radiation Use Efficiency of Forage Resources: A Meta‐Analysis
Agronomy Journal, 2019Core Ideas This is the first meta‐analysis of radiation use efficiency (RUE) of forage resources.RUE was most responsive to genotype, followed by N, water and light availability.Mean intraspecific differences were as large as interspecific ones.Most responses of RUE to the environment depended on the level of other factors.These results will enhance ...

Radiation Use Efficiency among Cotton Cultivars
Agronomy Journal, 1991AbstractCotton (Gossypium hirsutum L.) cultivars have diverse growth rates and fruiting characteristics that may be due to differences in radiation use efficiency. Potential growth rates were measured to see if differences could be attributed to radiation use efficiency or canopy light transmission coefficients.

Effect of Maize Maturity on Radiation‐Use Efficiency
Agronomy Journal, 1991AbstractMaize (Zea mays L.) production has expanded into short‐season regions but it is not known whether the radiation‐use efficiency (RUE, g MJ−1)1 of new early hybrids differs from those grown in traditional maize‐growing regions. In this study, spectral reflectance measurements were used to derive estimates of photosynthetically active radiation ...

Temperature affects radiation use efficiency in maize
Field Crops Research, 1993Abstract The objective of this work was to study, under field conditions, the effect of temperature on radiation use efficiency (RUE) of maize. Field evidence of the negative effect of low temperature on this variable is lacking. Experiments with different sowing dates and five years of experimentation with October plantings provided a range of ...
