Research ArticleOpen accessIn the abstractSustainability of Rainwater Harvesting Systems in Multistorey Residential BuildingsA. Rahman, J. Dbais, M. ImteazProblem statement: The urban water supply systems in Australian large cities, which generally depend on large surface water reservoirs, are highly stressed due to rapid urban growth and severe drought conditions during the current decade. To ensure the long term sustainability of urban water supply, various alternative water sources including rainwater tanks, grey water, wastewater and desalination plants are being … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 14,898 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Potassium Levels on Antioxidant Enzymes and Malondialdehyde Content under Drought Stress in Sunflower (Helianthus annuus L.)H. Soleimanzadeh, D. Habibi, M.R. Ardakani et al.Problem Statement: Drought stress as a major adverse factor can lower leaf water potential, leading to reduced turgor and some other responses and ultimately lower crop productivity in arid and semi arid zones. Sunflower is one of the main oil seed crops in Iran, where drought stress is the most limiting factor. Drought stress tolerance requires the activation of complex … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 1 · 31 Mar 2010 · 10,779 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhysiological Response of Soybean (Glycine max) to Foliar Application of Methanol Under Different Soil MoisturesFarzad Paknejad, Mojtaba Mirakhori, Majid Jami Al-Ahmadi et al.Problem statement: Many cultivated area are situated in arid zone, where crop photosynthesis and productivity has limited by drought. Thus any treatment, such as methanol, that improve plant water relation and reduce stress impacts, could be benefit. Approach: In order to investigate effects of methanol application on some physiological properties of soybean under low water stress, a factorial experiment was … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 4 · 31 Dec 2009 · 8,150 accessesView PDFCite
Research ArticleOpen accessIn the abstractResponse of Root Properties to Tripartite Symbiosis between Lucerne (Medicago sativa L.), Rhizobia and Mycorrhiza Under Dry Organic Farming ConditionsM. R. Ardakani, G. Pietsch, A. Moghaddam et al.Problem statement: It is generally considered that root turnover is a major contributor to organic matter and mineral nutrient cycles in organic managed agroecosystems. Approach: This study designed to investigate whether microbial activity could affect on root properties of Lucerne in an organically managed field under dry weather conditions. The trial was laid out as a factorial experiment in the … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 4 · 31 Dec 2009 · 8,504 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Super Absorbent Application on Antioxidant Enzyme Activities in Canola (Brassica napus L.) Cultivars under Water Stress ConditionsH. R. Tohidi-Moghadam, A. H. Shirani-Rad, G. Nour-Mohammadi et al.Problem statement: Drought stress significantly limits Canola (Brassica napus L.) growth and crop productivity. Hence, efficient management of soil moisture and study metabolic changes which occur in response to drought is important for agricultural production of this Crop. Approach: For a better understanding of drought tolerance mechanisms and improving soil water content management strategies, an experiment was laid out in … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 3 · 30 Sep 2009 · 8,603 accessesView PDFCite
Research ArticleOpen accessIn the abstractRainfall Depth-Duration-Frequency Relationships for South Carolina, North Carolina, and GeorgiaJ. P. Raiford, N.M. Aziz, A.A. Khan, D.N. PowellThe depth-duration-frequency curves and isopluvial maps for the region encompassing South Carolina, North Carolina, and Georgia were developed using the available rainfall data. The aim was to update the existing intensity-duration-frequency curves in the region and obtain these curves at ungauged sites throughout the region using the newly developed rainfall frequency analysis techniques. A total of 17 durations ranging from … …American Journal of Environmental Sciences, Vol. 3, Issue 2 · 30 Jun 2007 · 7,323 accessesView PDFCite
Research ArticleOpen accessIn the abstractMapping QTLs Linked to Physio-Morphological and Plant Production Traits under Drought Stress in Rice (Oryza sativa L.) in the Target EnvironmentS. Michael Gomez, S. Satheesh Kumar, P. Jeyaprakash et al.Drought stress is a major constraint for rice (Oryza sativa L.) production and yield stability in rainfed ecosystems. Identifying genomic regions (QTLs) contributing in drought resistance will help to develop rice cultivars suitable for water-limiting environments through marker-assisted breeding. QTLs linked to physio-morphological and plant production traits under drought stress in the field were mapped by evaluating 177 F6 recombinant … …American Journal of Biochemistry and Biotechnology, Vol. 2, Issue 4 · 31 Dec 2006 · 14,471 accessesView PDFCite

The researcher used … …Journal of Social Sciences, Vol. 1, Issue 3 · 30 Sep 2005 · 6,953 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordIntroduction of the Pasture Plant Fescue (Festuca valesiaca) for the Improvement of Degraded Pastures in the Steppe Zone of KazakhstanMeldebekova Nurgul Alikhanovna, Seitbattalova Ainur Islamovna, Ainebekova Bakyt Alpysbaevna et al.This study presents the results of a comprehensive evaluation of Festuca valesiaca, a dominant perennial grass species widely used in steppe ecosystems for pasture improvement. Previous research has demonstrated the importance of native fescue species in enhancing productivity and resilience of degraded rangelands under arid conditions. However, breeding efforts for this species in Kazakhstan remain insufficiently developed. The research was … …OnLine Journal of Biological Sciences, Vol. 26, Issue 3 · 14 Sep 2026 · 662 accessesView PDFCite
