EditorialOpen accessIn the abstractThe Timeless Contribution of Rootstocks towards Successful Horticultural Farming: From Ancient Times to the Climate Change EraIoannis E. PapadakisGrafting is a horticultural practice by which living vegetative plant organs (root, stem and/or buds) of either the same genotype or, usually, different genotypes belonging to the same species, genus, subfamily and/or family, are tightly connected to each other to form a double-compound plant. In fact, it is a method of asexual (clonal-vegetative) propagation of plants. The basal part of … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 4 · 16 Dec 2016 · 9,527 accessesView PDFCite
EditorialOpen accessIn the abstractProtecting crop species from biotic and abiotic constraints in the era of Global Change: are we ready for this challenge?Marco Landi, Giovanni BenelliReliable and affordable supply of food is of crucial importance to the progress and stability of human societies. During the last century, we have assisted to an extraordinary increase of crop yields, especially for the most widespread and consumed crop species, such as rice, wheat, corn and soybean. The Broadbalk experiment, one of the oldest continuous agronomic experiments in the … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 2 · 4 Jun 2016 · 8,402 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpatial Analysis and Modeling the Nitrogen Flush after Rainfall Events at the Field Scale in SWATElizabeth Brooke Haney, Richard Lee Haney, Jeffrey George Arnold et al.Current nitrogen (N) models tend to neglect the contribution of the microbial population to the plant available N pool, resulting in an underestimation of yield and possible over or underestimation of N runoff from natural and agricultural landscapes. We used the measurement of microbial activity coupled with the measurement of their food source, water extractable nitrogen (N) and carbon (C), … …American Journal of Environmental Sciences, Vol. 12, Issue 2 · 11 Apr 2016 · 7,232 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Nano Silica on the Compressive Strength of Harden Cement Paste at Different Stages of HydrationJustin Montgomery, Taher M. Abu-Lebdeh, Sameer A. Hamoush, Miguel PicornellThis study investigated the compressive strength of hardened cement paste and the formation of Calcium Silicate Hydrate (C-S-H) with the addition of nano silica (SiO2). Compressive strength testing was performed using MTS and Forney testing machines to determine stress-strain curves and compressive strength of the materials. The hydration process and formation of C-S-H and Calcium Hydroxide (CH) was examined using … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 1 · 13 Mar 2016 · 8,340 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Use of Nano Silica for Improving Mechanical Properties of Hardened Cement PasteIntisar Kuli, Taher M. Abu-Lebdeh, Elham H. Fini, Sameer A. HamoushThe influence of adding Nano particles of silicon dioxide (SiO2) on cement pastes was studied for both water and vacuum curing methods. Specimens made up of different percentage of Nano Silica were tested at different ages ranging from 3-56 days. The effect of (5-20 nm) Nano-Silica on the strength development of Nano-cement was determined using Material Tests System (MTS). The … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 1 · 13 Mar 2016 · 9,087 accessesView PDFCite
Research ArticleOpen accessIn the abstractStudy of Supercritical Coal Extraction in Toluene Containing FluidsPeter Nikolayevich Kuznetsov, Svetlana Mikhaylovna Kolesnikova, Ludmila Ivanovna Kuznetsova, Anastasia Valerievna KazbanovaThe conversion of brown coals and sapropelic coal in toluene containing mixtures with co-solvents (water, ethanol and tetralin) was studied under sub- and supercritical conditions within the temperature range of 375-550°C and at pressures from 7 to 40 MPa. It was found that the extent of coal extraction in the toluene solvent medium, at 400°C, was significantly increased by the … …American Journal of Applied Sciences, Vol. 13, Issue 3 · 1 Mar 2016 · 7,615 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of In Vitro Nitrogen Nutrition to Phalaenopsis deliciosa Seedling GrowthChieh Wean Choong, Chin Hao Lim, Zherui Xiong, Siew Mee ChoongIn a continuous effort to conserve Phalaenopsis species, the optimization of a previously designed defined medium was carried out to understand the effect of in vitro nitrogen nutrition on Phalaenopsis deliciosa Rchb.f. In order not to alter the nutrient balance, macronutrient level instead of solely Nitrogen (N) was adjusted. Seedlings were obtained from in vitro germination and randomly inoculated on … …OnLine Journal of Biological Sciences, Vol. 16, Issue 1 · 16 Dec 2015 · 7,829 accessesView PDFCite
Research ArticleOpen accessIn the abstractIMPROVING PHOSPHORUS NUTRITION OF COTTONWalter B. Gordon, Larry Murphy, Pawel WiatrakCrop recovery of applied Phosphorus (P) fertilizer can be low, especially during season of low soil temperature, which decreases plant root growth and nutrient uptake. The H2PO4- or HPO4-2 anions readily react with soil cations such as Calcium (Ca), Magnesium (Mg), iron (Fe) and Aluminum (Al) to produce various phosphate compounds of very limited water solubility. Specialty Fertilizer Products (SFP), … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 3 · 10 May 2014 · 7,112 accessesView PDFCite
Research ArticleOpen accessIn the abstractCLIMATE CHANGE IMPACT ASSESSMENT ON WATERSHED HYDROLOGY: A COMPARISON OF THREE APPROACHESSomsubhra Chattopadhyay, Manoj K. JhaSeveral methods of impact assessment have been developed over the years which basically incorporate future climate projections of atmospheric-ocean circulation based climate models into the simulation of land surface hydrological processes. This study attempted to evaluate three methods of climate change impact assessment: (a) Frequency perturbation method, (b) direct method and (c) delta change method. A well-calibrated hydrologic model, Soil … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 1 · 27 Mar 2014 · 8,604 accessesView PDFCite
Research ArticleOpen accessIn the abstractIMPROVING PHOSPHORUS NUTRITION OF CORNWalter B. Gordon, Larry Murphy, Pawel WiatrakPhosphorus (P) generally occurs in soils as the anions H2PO4- or HPO4-2 depending on soil pH. These anions readily react with soil cations such as calcium, magnesium, iron and aluminum to produce various phosphate compounds of very limited water solubility. Crop recovery of applied phosphate fertilizer can be quite low during the season of application. In addition, the large amounts … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 3 · 18 Mar 2014 · 7,447 accessesView PDFCite
