LIGHT INTERCEPTION AND PRODUCTIVITY IN RICE

Madras Agricultural Journal, 1992
A study was carried out to determine the relationship between light interception and productivity in rice. Cultivar difference could be observed in leaf area index, leaf angle, light extinction co-efficient (k), dry matter production grain yield. The study suggests that the rice cultivar with optimum leaf area index, upright leaves (low leaf angle) and

Light interception by isolated plants

Agricultural Meteorology, 1979
Abstract Foliage of single plants invariably appears to be nonuniformly distributed when viewed from the direction of the sun. The nonuniformity of foliage in space and its constraint within an envelope should both be considered when analyzing light interception.

Light Interception Efficiency Measurements

Journal of Agronomic Education, 1972
ABSTRACTLight interception efficiency of leaves with widely different display patterns is measured in this exercise. An extinction coefficient (k) is used to study differences among species in their light interception characteristics. A grass represents an inefficient light intercepting canopy, while a legume stand represents a relatively efficient ...

THE EFFECTS OF NITROGEN NUTRITION ON LIGHT INTERCEPTION PARAMETERS

Acta Horticulturae, 2006
Parameters of light interception have an important role in plant growth and dry matter production. Those parameters are: leaf area index (LAI), cumulative interception (CI), light interception (I) and light use efficiency (LUE). The aim of the presented research was to investigate the effect of nitrogen nutrition on light interception parameters and ...

LIGHT INTERCEPTION OF LIGHTING SYSTEMS, VENLO AND WIDE SPAN TYPE GREENHOUSES

Acta Horticulturae, 2006
TNO has developed a computer program to calculate the light interception of the greenhouse structure using an improved half-perimeter method, taking into account reflections and shadowing. This program is used to compare the light interception of Venlo and Wide span type greenhouse.
