Papers published in Hydrology and Earth System Sciences Discussions are under open-access review for the journal Hydrology and Earth System Sciences Abstract Stand transpiration was measured during the 2003 and 2004 growing seasons using heat dissipation sap flow sensors in a Scots pine (Pinus sylvestris L.) and a pubescent oak (Quercus pubescens Willd.) forest located in a montane area of the ...

Abstract Identification of suitable habitat for invasive weeds and their projected infestation extent across different land use cover types under a changing climate is crucial the broad management goals prevention, detection, rapid response. In this study, we adopted an ensemble approach species distribution models to project potential annual grass, Ventenata dubia , within Gallatin County alon...

High-latitude lakes are sensitive to climate change and store information about large-scale circulation changes catchment-integrated processes. Lakes mainly recharged by meteoric water, meaning that some lake sediment proxies may indirectly archive the stable isotopic composition of hydrogen (?2H) oxygen (?18O) past precipitation. Yet, despite similar precipitation input, within a region exhibi...

Cotton is a precious commodity that offers raw material to the textile industry. This crop grown in tropical and sub-tropical regions of world. Abiotic stresses exerts negative impact on cotton production, but water scarcity has worst impact. It rising due current situation, which global warming producing decrease precipitation while an increase evapo-transpiration causing agricultural drought....

Abstract Plant growth regulators are chemical substances which govern all the factors of development and within plants. The application plant to crops modifies hormonal balance leading increased yield, enhanced crop tolerance against abiotic stress improved physiological trait crops. Paclobutrazol (PBZ) [(2RS, 3RS)-1-(4-chlorophenyl)- 4, 4-dimethyl-2-(1H-1, 2, 4-trizol-1-yl)-pentan-3-ol], is on...

Crop coefficient values are used to estimate crop evapotranspiration (ETc) for determining irrigation scheduling. Many important crop biophysical properties such as Percentage Vegetation Cover and Leaf Area Index can be estimated from remotely sensed Vegetation Index, in order to quantify real time vegetation growth dynamics. The objective of this study was to understand the effectiveness of ba...

We determine the vegetation type for the CART from a database generated by the U. S. Geological Survey (USGS 1990). Soil types were provided by the Atmospheric Radiation Measurement (ARM) Program from the State Soil Geographic (STATSGO) database and mapped into the USDA classifications described by Clapp and Hornberger (1978). To provide the input parameters of temperature, pressure, humidity, ...

Stomatal guard cells are functionally specialized epidermal cells usually arranged in pairs surrounding a pore. Changes in ion fluxes, and more specifically osmolytes, within the guard cells drive opening/closing of the pore, allowing gas exchange while limiting water loss through evapo-transpiration. Adjustments of the pore aperture to optimize these conflicting needs are thus centrally import...

Maize and Indian mustard are significant crops in semi-arid climate zones of India. Improved water management requires precise scheduling of irrigation, which in turn requires an accurate computation of daily crop evapotranspiration (ETc). Daily crop evapotranspiration comes as a product of reference evapotranspiration (ET0) and the growth stage specific crop coefficients modified for daily var...

Understanding the fates of soil hydrological processes and nitrogen (N) is essential for optimizing the water and N in a dryland crop system with the goal of obtaining a maximum yield. Few investigations have addressed the dynamics of dryland N and its association with the soil hydrological process in a freeze-thawing agricultural area. With the daily monitoring of soil water content and acquis...
