The Design and Implementation of the Leaf Area Index Sensor
Sensors, 2015 The quick and accurate acquisition of crop growth parameters on a large scale is important for agricultural management and food security. The combination of photographic and wireless sensor network (WSN) techniques can be used to collect agricultural ...

Comparative analysis of changes in leaf area index in different wheat genotypes exposed to high temperature stress by late sown condition [PDF]
, 2017 High temperature stress during grain-filling period is one of the major environmental constraints limiting the grain yield of wheat in India. Crop growth response and relative performance of yield components of 12 wheat (Triticum aestivum) genotypes were

A Mixed Data-Based Deep Neural Network to Estimate Leaf Area Index in Wheat Breeding Trials [PDF]
, 2020 Remote and non-destructive estimation of leaf area index (LAI) has been a challenge in the last few decades as the direct and indirect methods available are laborious and time-consuming.

Computer simulation modeling of Leaf Area Index (LAI) in maize
Acta Agraria Debreceniensis, 2014 This study presents a PHP-based model capable of calculating maize leaf area index. The model calculates LAI from emergence to 75% silking. The basis of calculation is represented by the daily average temperature values. The usability of the model was tested using three years' temperature and LAI data series from the values obtained by the weather ...

Effect of fruit-to-leaf area ratio on fruit quality and vegetative growth of 'bing' sweet cherry trees at optimal leaf area index [PDF]
, 2008 Fruit yield and quality determine grower income from commercial sweet cherry orchards. The objective of this study was to determine the effect of Fruit Number to Leaf Area Ratio (FNLAR, fruit m-2 LA) on Mean Fruit Weight (MFW), firmness (F), soluble ...

Behaviour of carbon dioxide and water vapour flux densities from a disturbed raised peat bog [PDF]
, 2002 Measurements of carbon dioxide and water vapour flux densities were carried out for a disturbed raised peat bog in the north of the Netherlands during an 18 month continuous experiment. Tussock grass (sp. Molinea caerulae) mainly dominated the vegetation

Variability and bias in active and passive ground-based measurements of effective plant, wood and leaf area index [PDF]
, 2018 In situ leaf area index (LAI) measurements are essential to validate widely-used large-area or global LAI products derived, indirectly, from satellite observations.
