Radiation Use Efficiency among Cotton Cultivars

Agronomy Journal, 1991
AbstractCotton (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.

Variability of Barley Radiation‐Use Efficiency

Crop Science, 2004
Radiation‐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, 1995
AbstractThe 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 ...

Radiation Use Efficiency

1999
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

2016
Photosynthesis 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.

Variation in Crop Radiation‐Use Efficiency with Increased Diffuse Radiation

Crop Science, 1992
Radiation‐use efficiency (RUE; grams of biomass accumulated, divided by total solar radiation intercepted) has proven to be a useful variable for quantifying biomass accumulation by crops. Experimental results and theoretical analysis indicate that differences in RUE exist among species, but that RUE for unstressed conditions is relatively stable ...

Radiation interception, radiation use efficiency and growth of barley cultivars

Australian Journal of Agricultural Research, 1993
Dry 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

Temperature affects radiation use efficiency in maize

Field Crops Research, 1993
Abstract 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 ...

Radiation Use Efficiency of Forage Resources: A Meta‐Analysis

Agronomy Journal, 2019
Core 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 ...
