crop productivity, water use efficiency (wue), and microbial biomass c and n in rainfed dry area are influenced by tillage, rotation, and crop residue management. field experiments were conducted during 2005-08 to study the effect of tillage, crop rotation, and crop residue retention on oat fodder yield, water use efficiency, and microbial biomass c (mbc) and n (mbn) under semi-arid conditions ...

Mediterranean viticulture is highly dependent on soil water availability. Moreover, global warming likely to increase average temperatures and the frequency of heat waves, thus leading greater scarcity. To cope with this situation, much research focused selection genotypes higher use efficiency (WUE). Several previous studies indicated that WUE varies between Tempranillo cultivar some showing i...

Water use efficiency (WUE) is an important variable to explore coupled relationships in carbon and water cycles. In this study, we first compared the spatial variations of annual gross primary productivity (GPP) evapotranspiration (ET) using four GPP ET products. Second, selected products closest flux towers data estimate WUE. Finally, quantitatively analyzed impact climate change soil content ...

Water-use efficiency (WUE) is a crucial physiological index in carbon–water interactions and defined as the ratio of vegetation productivity to water loss. The variation climatic variables drought have most significant effects on WUE evapotranspiration (ET). Nevertheless, how varies with climate factors processes Tianshan Mountains (TMS) still poorly understood. In present work, we analyzed spa...

limited information is available on water and nitrogen (n) management of sugarcane (saccharum officinarum l.) in khuzestan, southwestern iran, where this crop is currently and extensively grown under heavy irrigation and n fertilization. therefore, a field experiment was conducted from september 2000 to march 2002 at the research department of karoon agro-industry in khuzestan to determine the ...

This study aimed to evaluate the interaction of environmental variables and Water Use Efficiency (WUE) via multivariate analysis understand importance each variable in carbon–water balance MATOPIBA. Principal Component Analysis (PCA) was applied reduce spatial dimensionality identify patterns by using following data: (i) LST (MOD11A2) WUE (ratio between GPP-MOD17A2 ET-MOD16A2), based on MODIS o...

Plants control water-use efficiency (WUE) by regulating water loss and CO2 diffusion through stomata. Variation in stomatal has been reported among lineages of vascular plants, thus giving rise to the possibility that different may show distinct WUE dynamics response stress. Here, we compared gas exchange decreasing leaf potential four ferns nine seed plant species exposed a gradually intensify...

The socio-economic development of a country is highly dependent on water availability. Nowadays, increasing scarcity major global challenge. Continuing improvements in water-use efficiency are essential for cotton production sustainability. Reduced irrigation could be solution to shortage the arid climate without compromising yield. Therefore, two-year field study was conducted assess effect tw...

Abstract Photosynthetic rate and water use efficiency (WUE) are crucial for the sustainable of in agriculture. Our objective was to analyze variability photosynthetic related traits maize ( Zea mays L.) other summer crops a temperate humid area. We evaluated parameters three years compared them pigeonpea chickpea, adapted arid environments, pepper, tomato common bean, as irrigated crops. Variab...
