Research ArticleOpen accessIn the abstractMorphological Variability and Races of Fusarium oxysporum f.sp. ciceris Associated with Chickpea (Cicer arietinum) CropsRosa Marina Arvayo-Ortiz, Martin Esqueda, Evelia Acedo-Felix et al.Abstract: Problem statement: Mexico is the third largest producer and exporter of chickpea (Cicer arietinum), with the states of Sinaloa and Sonora accounting for 70 and 20% of Mexico’s production, respectively. The most damaging disease affecting this species is caused by Fusarium oxysporum f.sp. Ciceris (FOC), which causes losses of up to 60% in Sonora. The objective of this study … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 1 · 31 Jan 2011 · 8,853 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEvolution of Spatial Correlation of Mean Diameter: A Case Study of Trees in Natural Dipterocarp ForestRafida M. Elobaid, Mahendran Shitan, Noor Akma Ibrahim et al.Problem statement: Spatial modeling has many applications in various fields like agriculture, meteorology, forestry and it takes into consideration the spatial correlation structures. In the field of forestry the growth rate, in particular, the diameter of trees is usually an important parameter. The growth rate of trees in a forest is likely to be influenced by various factors like nutrients, … …Journal of Mathematics and Statistics, Vol. 5, Issue 4 · 31 Dec 2009 · 7,536 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEvaluation of Some Organic Pollutants Transport into the Shallow Groundwater and Surface Water of Jiaxing Landfill AreaSouleymane Keita, Zhonghua Tang, Shaogang Dong, Yuehua JiangProblem statement: Hangjiahu regions belong to the Yangtze River Delta region in Zhejiang Province in China. The vast majority of this region is flat, so surface and groundwater both have a low flow rate. With the rapid economic development of the area, a large number of industrial and domestic garbage are generated. These landfill or garbage are exposed and stacked. … …American Journal of Applied Sciences, Vol. 6, Issue 12 · 31 Dec 2009 · 8,283 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAlnus subcordata C.A.M. Cambium Cells Dynamics Along Transport Corridors in Hyrcanian ForestsAidin Parsakhoo, Hamid Jalilvand, Mehdi SheikhiProblem statement: In this study, we considered transport corridors and sampling aspects to be the major indicators of ecological effects on Alder (Alnus subcordata) cambium cells dynamics. Approach: Thus, 240 cores were taken from forest-facing and road-facing trunk of Alder trees along Amre, Neka and Darab Kola transport corridors in hyrcanian Forests of Iran. Results showed that the roads corridor … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 6,950 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAssessment of Pulverised Fly Ash (PFA) as an Ameliorant of Lead Contaminated SoilsEdmond Gatima, Mwinyikione Mwinyihija, Ken KillhamFly Ash (FA) is obtained by electrostatic or mechanical precipitation of dust-like particles from the flue gases of furnace fired with coal or lignite at 1100 to 1400°C. About 95-99% of Fly Ash consists of oxides of Si, Al, Fe and Ca, about 0.5 to 3.5% consists of Na, P, K and S and the remainder is composed of trace … …American Journal of Environmental Sciences, Vol. 1, Issue 3 · 30 Sep 2005 · 7,014 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSimulation Model for Feasibility Studies on Bioremediation of Uranium Mill Tailings using Hyper Accumulator Chrysopogon zizanioidesH. Shanmugasundaram, Sathesh Kumar Annamalai, Kantha Deivi Arunachalam et al.Contamination of environment by uranium is expected in places where mining of uranium ore and processing, nuclear testing and reactor operations when the control measures are not effective. The daughter radionuclides of the ores, chemical additives and residual uranium are the maincomponents of processed waste from uranium industries. The bioremediation of contaminated areas using plant species or group of the … …American Journal of Environmental Sciences, Vol. 12, Issue 6 · 11 Dec 2016 · 8,872 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordRestoration of Biodiversity and EcosystemIgnacio Santa-Regina, M. C. Santa-ReginaSuccession is one of the most studied processes in ecology and succession theory provides strong predictability. However, few attempts have been made to influence the course of succession thereby testing the hypothesis that the passage of one stage is essential to enter a next one. At each stage of succession ecosystem processes may be affected by the diversity of species … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 1 · 10 Mar 2013 · 6,984 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordEvaluation of Leaf Total Nitrogen Content for Nitrogen Management in a Malaysian Paddy Field by Using Soil Plant Analysis Development Chlorophyll MeterA. Gholizadeh, M. S. M. Amin, A. R. Anuar, W. AimrunProblem statement: Laboratory plant testing is usually time-consuming and high-costing. Hence, plant nutrient variability must be measured rapidly and the information made known to the farmers before the new season starts. Site-specific crop management, well-established in some developed countries, is now being considered in other places such as Malaysia. Approach: The application of site-specific management principles and techniques to diverse … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 4 · 31 Dec 2009 · 9,238 accessesView PDF Cite
