Infrared Estimation of Canopy Temperature as Crop Water Stress Indicator

Bryant Canopy temperature variability as an indicator of crop water stress severity

Irrigation scheduling requires an operational means to quantify plant water stress. Remote sensing may offer quick measurements with regional coverage that cannot be achieved by current ground-based sampling techniques. This study explored the relation between variability in fine-resolution measurements of canopy temperature and crop water stress in cotton fields in Central Arizona, USA. Using ...

Evaluation of Crop Water Stress Index, Canopy Temperature and Grain Yield of Five Iranian Wheat Cultivars Under Late Season Drought Stress

Abstract In order to evaluate crop water stress index (CWSI) and canopy temperature of wheat cultivars under terminal drought stress, a field experiment was conducted at the Agricultural Research Station of Shiraz University, Shiraz, during 2009 growing season. Five wheat cultivars including Shiraz, Bahar, Pishtaz, Sistan and Yavaros and four levels of water regime including well watering [Irr...

Water stress of sugarbeet as related to leaf and canopy temperatures and to leaf Water content

Comparing canopy temperature and leaf water potential as irrigation scheduling criteria of potato in water-saving irrigation strategies

Irrigation scheduling is important in irrigation water management. In this study, full (FI),deficit (DI) and partial root drying (PRD) irrigation strategies were applied in Agria and Ramospotato cultivars. Canopy temperature (CT) and leaf water potential (LWP) were assessed as thepotential tools for irrigation scheduling during the vegetative and productive growth stages.LWP varied between ca. ...

determination of crop water stress index for pistachio trees under subsurface drip irrigation using canopy-air temperature difference

this study was conducted to determine the possibility of a crop water stress index (cwsi) to schedule irrigation for pistachio tree under subsurface drip irrigation. the effects of two irrigation intervals consisting 3 (i3) and 14 (i14) days based on measuring soil water content were investigated on the cwsi. from 22 may (doy 143) to 22 september (doy 266), the evapotranspiration in i3 and i14 ...
