abstract- the crop water stress index (cwsi) is the most common index to monitor and assess crop water stress, based on canopy temperature. to calculate cwsi, upper and lower baselines adaptable to different environments are needed. in this study, empirical and theoretical limiting baseline equations were developed to determine eggplant cwsi values at different levels of water deficit and salin...

The capability to monitor water status from crops on a regular basis can enhance productivity and water use efficiency. In this paper, high-resolution thermal imagery acquired by an unmanned aerial vehicle (UAV) was used to map plant water stress and its spatial variability, including sectors under full irrigation and deficit irrigation over nectarine and peach orchards at 6.12 cm ground sample...

T e crop water stress index (CWSI), developed at the USDA-ARS [LS. Water Conservation Laboratory, Phoenix, Arizona, is a commonly used index for detection of plant stress based on the difference between foliage and air temperature. Application of CWSI at local and refzional scales has been hampered by the difficulty of measuring foliage temperature of partially vegetated fields. Most hand-held,...

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...

Due to climate change, the application of water saving strategies is of particular interest. The aim of this study was to evaluate the effects of deficit irrigation (DI) and partial root-zone drying (PRD) techniques on the crop water stress index (CWSI), water use efficiency (WUE), and quality parameters in processing tomatoes grown in open field conditions in a Mediterranean climate. Two culti...

Word Sense Induction (WSI) is an important topic in natural langage processing area. For the bakeoff task Chinese Word Sense Induction (CWSI), this paper proposes two systems using basic clustering algorithms, k-means and agglomerative clustering. Experimental results show that k-means achieves a better performance. Based only on the data provided by the task organizers, the two systems get FSc...
