Crop water stress
WebApr 13, 2024 · Salinity stress is among the key challenges for sustainable food production. It is continuously increasing against the backdrop of constant climate change and anthropogenic practices leading to a huge drop in soil, water, and cultivated crop quality and productivity. Halotolerant plants represent hot spots for endophytic bacteria which …

WebJun 22, 2014 · Research was conducted in northern Colorado in 2011 to estimate the crop water stress index (CWSI) and actual transpiration (T a) of maize under a range of irrigation regimes. The main goal was to ... WebNov 25, 2015 · Climate change is projected to reduce average yields over the next century for major U.S. field crops—corn, soybeans, rice, sorghum, cotton, oats, and silage—under both irrigated and dryland production, relative to projected yields assuming no climate change. Yields for wheat, hay, and barley, by contrast, are often projected to increase.
WebApr 13, 2024 · The water is extracted by the root system in the root zone and represents a loss of water in the soil, and thus ET is used interchangeably with crop water use. Crop water stress can be detected using ET and Evaporative Stress Index (ESI) (Anderson et al. 2016). For irrigated crops, ET measures the water used to grow food. WebPlant growth and productivity are adversely affected by water stress. Therefore, the development of plants with increased survivability and growth during water stress is a major objective in the breeding crops. Water …
WebApr 10, 2024 · With the crop water stress index, infrared thermometry is commonly used to monitor water stress, but it has also been extended to estimate crop evapotranspiration (ET c). However, the high costs of sensors, the need to program and wire dataloggers, and issues with data quality may make it difficult to implement thermometry-based scheduled ... WebDec 11, 2024 · With increasing water resources stress under climate change, it is of great importance to deeply understand the spatio-temporal variation of crop water requirements and their response to climate change for achieving better water resources management and grain production. However, the quantitative ev …
WebMar 31, 2024 · The crop water stress index (CWSI), based on canopy temperature (T c), has been widely used in evaluating plant water status and planning irrigation scheduling, but whether CWSI can diagnose the stress status of crops and predict the physiological traits and growth under combined water and salt stress remains to be further studied.
WebOnly a portion of the available water holding capacity is easily used by the crop before crop water stress develops. As illustrated in Figure 1, soil’s MAD is less than its total AWC. Historically, irrigations have been planned to prevent the soil water deficit from exceeding 50 percent of the total available water capacity in the rooting zone. parking tower hill londonWebHowever, reducing crop consumptive water use or evapotranspiration through water stress can have a negative impact on production economics if not precisely managed. Remote sensing of crop canopy temperature is a scientifically-based and easy-to-apply method that can be used at field scales to evaluate crop water status at or near real-time. tim hortons 2 for 4 breakfast sandwich 2019WebThe crop water stress index (CWSI) combines these factors and yields a measure of plant water stress. Two forms of the index have been proposed, an empirical approach as reported by Idso et al. (1981), and a theoretical approach reported by Jackson et al. (1981).
