Intercepted Photosynthetically Active Radiation (PAR) and Spatial and Temporal Distribution of Transmitted PAR under High-Density and Super High-Density Olive Orchards

Agriculture, 2021
We quantified the photosynthetically active radiation (PAR) interception in a high-density (HD) and a super high-density (SHD) or hedgerow olive system, by measuring the PAR transmitted under the canopy along transects at increasing distance from the ...

Effect of Radiation Interception and Canopy Temperature on Growth, Yield and Quality in Banana Cv. Grande Naine (AAA) under Different Planting Densities

Journal of Horticultural Sciences, 2015
A study was made to test the effect of radiation interception and canopy temperature under different planting densities [T1- 1.5m x 1.5m (4,444 plants/ha); T2- 2m x 2m (2500 plants/ha); T3- 1.5m x 2.5m (2666 plants/ha); T4- 2m x 2.5m (2000 plants/ha); T5-

Radiant energy distribution in guava (Psidium guajava L.) plants at different spacings

Journal of Agrometeorology, 2009
The study on radiant energy distribution in guava was carried out to optimize the planting density with respect to solar radiation interception by the plants to get higher yield of good quality fruits per unit area.

Competition for Light Interception in Cotton Populations of Different Densities

Agronomy, 2021
Modification of the cotton canopy results in shade avoidance and competition for light, which shows that density and spatial arrangement of cotton have a great impact on light interception.

Radiation interception and radiation use efficiency in mixtures of winter cover crops

Field Crops Research, 2021
Abstract Context Cover crops are sown in autumn after harvest of a main crop to capture residual nitrogen and to build biomass that will contribute to soil organic matter after being ploughed under. Mixtures are purportedly more productive than pure stands of single species.

A sensitivity study of daytime net radiation during snowmelt to forest canopy and atmospheric conditions [PDF]

, 2004
This study investigates the dependence of net radiation at snow surfaces under forest canopies on the overlying canopy density. The daily sum of positive values of net radiation is used as an index of the snowmelt rate.

The effect of strip orientation and width on radiation interception in maize–soybean strip intercropping systems

Food and Energy Security, 2022
Maize–soybean intercropping systems are widely used in developing countries, but few studies have been performed to optimize such systems. The effects of strip width and orientation on photosynthetically active radiation (PAR) distribution ...

Light interception and radiation use efficiency of cotton [PDF]

, 2021
Η συσσώρευση ξηράς ουσίας από μια καλλιέργεια είναι μια άμεση συνάρτηση της ποσότητας της ακτινοβολίας που αναχαιτίζεται από την φυλλική επιφάνεια. Η αποτελεσματικότητα μιας καλλιέργειας να μετατρέπει την αναχαιτισμένη ακτινοβολία σε ξηρή μάζα ονομάζεται αποδοτικότητα χρήσης ακτινοβολίας.

Modelling radiation interception and radiation use efficiency for sugar beet under variable climatic stress

, 2001
European sugar beet crops suffer drought stress, and climate change is likely to increase the frequency and severity of drought. Changes in rainfall pattern may also affect the radiation environment.
