Light interception and radiation use efficiency in temperate quinoa (Chenopodium quinoa Willd.) cultivars
(Elsevier Science, 2008-08)
Sea level quinoas are grown at low altitudes in Central and Southern Chile. Both sensitivity to photoperiod and response to temperature largely determine quinoa adaptation, but crop biomass production must be quantified ...

Lost forever? Ecosystem functional changes occurring after agricultural abandonment and forest recovery in the semiarid Chaco forests
(Elsevier, 2019-02-10)
Semiarid forests are worldwide threatened by land use changes, particularly agriculture. However, in some cases, due to particular economic or social processes, agriculture ends and forests may or may not recover to their ...
Manejo de canola em terras baixas: características do dossel, interceptação da radiação e produtividade de grãos
(Universidade Federal de Santa MariaBrasilAgronomiaUFSMPrograma de Pós-Graduação em AgronomiaCentro de Ciências Rurais, 2021-08-27)
The modification of microclimatic conditions in agricultural crops can substantially affect the growth and yield of grains in waterlogged environments. Therefore, the present study aimed to determine the effect of the ...
Milk production and composition of dairy cows grazing elephant grass under two grazing intervalsProdução e composição do leite de vacas mantidas em pastagens de capim-elefante submetidas a duas frequências de pastejo
(2010-01-01)
The objective of this study was to evaluate two grazing intervals (IG) for elephant grass (Pennisetum purpureum Schum cv. Cameroon) pasture: one variable, determined by the entry of animals to the paddocks when 95% of ...
Características produtivas e qualitativas do capim-elefante pastejado em intervalo fixo ou variável de acordo com a interceptação da radiação fotossinteticamente ativa
(Sociedade Brasileira de Zootecnia, 2010)
Objetivou-se avaliar dois intervalos de pastejo de pastos de capim-elefante (Pennisetum purpureum Schum.): um intervalo variável, quando o dossel atingisse 95% de interceptação da radiação fotossinteticamente ativa, e um ...
Simple regression models to estimate light interception in wheat crops with Sentinel‐2 and a handheld sensor
(Crop Science Society of America, 2020-04)
Capture of radiation by crop canopies drives growth rate, grain set, and yield. Since the fraction of photosynthetically active radiation absorbed by green area (fAPARg) correlates with normalized difference vegetation ...
A practical guide to estimating the light extinction coefficient with nonlinear models—a case study on maize
(BioMed Central, 2021-12)
Background: The fraction of intercepted photosynthetically active radiation (fPARi) is typically described with a non-linear function of leaf area index (LAI) and k, the light extinction coefficient. The parameter k is ...
