F  aMonitoring energy balance, turbulent flux partitioning, evapotranspiration and biophysical parameters of Nopalea cochenillifera (Cactaceae) in the Brazilian Semi-Arid environment.h[electronic resource]  c2023  aThe in-situ quantification of turbulent flux and evapotranspiration (ET) is necessary to monitor crop performance in stressful environments. Although cacti can withstand stressful conditions, plant responses and plant?environment interactions remain unclear. Hence, the objective of our study was to investigate the interannual and seasonal behaviour of components of the surface energy balance, environmental conditions, morphophysiological parameters, biomass yield and water relations in a crop of Nopalea cochenillifera in the semi-arid region of Brazil. The data were collected from a micrometeorological tower between 2015 and 2017. The results demonstrate that net radiation was significantly higher during the wet season. Latent heat flux was not significant between the wet season and dry season. During the dry-wet transition season in particular, sensible heat flux was higher than during the other seasons. We observed a large decline in soil heat flux during the wet season. There was no difference in ET during the wet or dry seasons; however, there was a 40% reduction during the dry-wet transition. The wet seasons and wet-dry transition showed the lowest Evaporative Stress Index. The plants showed high cladode water content and biomass during the evaluation period. In conclusion, these findings indicate high rates of growth, high biomass and a high cladode water content and explain the response of the cactus regarding energy partitioning and ET.  aAbiotic stress  aBiomass  aClimate  aPlant-water relations  aBalanço de Energia  aCactaceae  aCactus Ficus Indica  aClima  aEvapotranspiração  aNopalea Cochenillifera  aBalanço energético  aCactos  aCondições ambientais  aEstresse abiótico  aParâmetros morfofisiológicos  aProdução de biomassa  aRadiação líquida  aRelações hídricas  aRendimento de biomassa1 aMORAIS, J.
