Effect of Radiation Environment on Radiation Use Efficiency and Growth of Sunflower
Crop Science, 1997The level of incident radiation and the proportion of radiation that is diffuse affects radiation use efficiency (RUE) in crops. However, the degree of this effect, and its importance to growth and yield of sunflower (Helianthus annuus L.) have not been established. A field experiment was conducted to investigate the effects of radiation environment on

Variability of Barley Radiation‐Use Efficiency
Crop Science, 2004Radiation‐use efficiency (e) is a crop‐dependent coefficient widely used in crop simulation models and in the physiological interpretation of crop response to the environment and management practices. Our objectives were to: (i) determine the e of spring barley (Hordeum vulgare L.), (ii) analyze the impact of weather variables and fraction of solar ...

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 ...

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).

Consequences of breeding on biomass, radiation interception and radiation-use efficiency in wheat
Field Crops Research, 1997Abstract Field experiments were conducted during 1991 and 1992 to identify the effect of wheat breeding on crop biomass production and its physiological determinants, i.e. radiation interception and radiation-use efficiency. To address this objective, biomass accumulation and its physiological attributes of seven cultivars (including a commercial ...

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 ...

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 ...
