The distilled water productivity of the single basin solar still is very limited. In this context, the design modification of a single basin solar still has been investigated to improve the solar still performance through increasing the productivity of distilled water. The experimental attempts are made to enhance the solar still productivity by using nanofluids and also by integrating the stil...

in order to investigation of irrigation management and plant density effects on water productivity of rice, a field experiment was conducted in the rice research institute of iran (rasht) during 2001 and 2002. the study was carried out in a split plot design with four different irrigation regimes as main plots and three plant densities as subplots. in this experiment, oryza2000 model was used t...

Abstract Negative pressure irrigation (NPI), which is a new subsurface technique, promotes vegetable yield, water productivity (WP), and nitrogen use efficiency (NUE). However, it not clear how NPI improves growth, especially in terms of supply characteristics uniformities soil nitrogen. In this study, cucumber pot experiment that had 0 kPa (PW1), –5 (PW2), –10 (PW3), –15kPa (PW4), traditional ...

The eastern Mediterranean faces a severe water crisis: water supply decreases due to climate change, while demand increases due to rapid population growth. The GLOWA Jordan River project generates science-based management strategies for maximizing water productivity under global climate change. We use a novel definition of water productivity as the full range of services provided by landscapes ...

India is the largest producer of rice (Oryza sativa L.) next to China in the world. Rice cultivation is a huge water demanding enterprise. In recent years, water table has depleted at a very rapid rate throughout the globe, thus, posing alarming threats and limiting the scope for cultivation of high water consuming crops especially rice. Challenges in maintaining the sustainability of rice farm...

Water Productivity (WP) of a crop defines the relationship between the economic or physical yield of the crop and its water use. With this concept it is possible to identify disproportionate water use or water-limited yield gaps and thereby support improvements in agricultural water management. However, too often important qualitative and quantitative environmental factors are not part of a WP ...

Heat-stressed crops suffer dehydration, depressed growth, and a consequent decline in water productivity, which is the yield of harvestable product as a function of lifetime water consumption and is a trait associated with plant growth and development. Heat shock transcription factor (HSF) genes have been implicated not only in thermotolerance but also in plant growth and development, and there...

The within-day, between-day and month-to-month variability of light attenuation and microalgal chlorophyll a (chl a ) and photosynthetic response was measured in San Antonio Bay, Texas, USA. Waters were shallow (<2 m) and turbid (attenuation coefficients of 0.7 to 15.3 m"), yet daily rates of primary production (0.1 to 2.5 g C d-') were comparable to those in much deeper and clearer estuaries. ...

Increasing water use and droughts, along with climate variability and land use change, have seriously altered vegetation growth patterns and ecosystem response in several regions alongside the Andes Mountains. Thirty years of the new generation biweekly normalized difference vegetation index (NDVI3g) time series data show significant land cover specific trends and variability in annual producti...
