Remote and proximal sensing assessment of water status and its correlation with yield on almond orchards in Southeast Spain

Álvaro Sánchez-Virosta, David Gómez-Candón, F. Montoya, Yaiza Pérez-García et autres

Abstract This study evaluates the potential of UAS-based and proximal sensing tools to assess water stress and how derived indices correlates with yield in almond orchards in the semiarid conditions of southeast Spain. Two commercial orchards with contrasting irrigation regimes were monitored …

Assessment of different remote sensing techniques to estimate the CWSI of almond trees using canopy temperature

Álvaro Sánchez-Virosta, Juan Manuel Sánchez, F. Montoya, David Gómez-Candón et autres

The radiometric temperature of the plants is known to be a good indicator of their level of water stress. The use of thermal cameras on board UAVs allows operational monitoring of the canopy temperature in orchard plantations at the single-tree level. The …

Cost-effective multispectral imaging system for detecting nitrogen over-fertilization under different temperatures in greenhouse sweet pepper plants

María Carmen Piñero, David Gómez-Candón, Ainara López-Maestresalas, Jacinta Collado‐González et autres

This study investigates the effects of nitrogen (N) excess under two temperature conditions on greenhouse-grown pepper plants ( Capsicum annuum L.), using a low-cost cablecam system for proximal remote sensing. Commonly used vegetation indices were analyzed to assess plant responses under varying …

Tuning the Monitoring of Actual Daily Evapotranspiration Merging Satellite Data Fusion and Surface Energy Balance

David Gómez-Candón, Álvaro Sánchez-Virosta, Yeray Pérez, Juan Manuel Sánchez et autres

The estimation of actual daily evapotranspiration (ET) at field scale from satellite imagery poses a challenge for water management due to the spatio-temporal limitations of the current sensors operating in the thermal infrared. This study introduces a methodology that aims to address …

A Remote Sensing Approach for Assessing Daily Cumulative Evapotranspiration Integral in Wheat Genotype Screening for Drought Adaptation

David Gómez-Candón, Joaquim Bellvert, Ana Pelechá, Marta S. Lopes

This study considers critical aspects of water management and crop productivity in wheat cultivation, specifically examining the daily cumulative actual evapotranspiration (ETa). Traditionally, ETa surface energy balance models have provided estimates at discrete time points, lacking a holistic integrated approach. Field trials …

Improving in-season wheat yield prediction using remote sensing and additional agronomic traits as predictors

Adrian Gracia‐Romero, Rubén Rufo, David Gómez-Candón, José Miguel Soriano et autres

The development of accurate grain yield (GY) multivariate models using normalized difference vegetation index (NDVI) assessments obtained from aerial vehicles and additional agronomic traits is a promising option to assist, or even substitute, laborious agronomic in-field evaluations for wheat variety trials. This …

Performance of the Two-Source Energy Balance (TSEB) Model as a Tool for Monitoring the Response of Durum Wheat to Drought by High-Throughput Field Phenotyping

David Gómez-Candón, Joaquim Bellvert, C. Royo

The current lack of efficient methods for high throughput field phenotyping is a constraint on the goal of increasing durum wheat yields. This study illustrates a comprehensive methodology for phenotyping this crop's water use through the use of the two-source energy balance …
