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 · 9,521 accessesView PDFCite
Case ReportOpen accessIn the abstractImpacts of Biogas Digestate on Crop Production and the Environment: A Bulgarian Case StudyNicholas Kathijotes, Vera Petrova, Elena Zlatareva et al.The water-energy nexus reveals that large amounts of energy is stored in used water and can be used as an energy source. Anaerobic fermentation is an excellent ecological waste treatment and a way of producing low cost electrical and thermal energy. By using digestate resulting from biogas production instead of synthetic fertilizers derived from natural gas, we can save energy, … …American Journal of Environmental Sciences, Vol. 11, Issue 2 · 29 May 2015 · 7,553 accessesView PDFCite
Research ArticleOpen accessIn the abstractPREPARATION OF ACTIVATED CARBON FROM PALM OIL SHELL BY CHEMICAL ACTIVATION WITH Na2CO3 AND ZnCl2 AS IMPRENATED AGENTS FOR H2S ADSORPTIONKanokorn HussaroHydrogen Sulfide (H2S, rotten-egg) is one of the major environmental pollutants having its sources in natural and anthropogenic activities. It’s had smell gas produced by anaerobic digestion in acid condition from organic and inorganic compounds containing sulphur, presents dual problems of its toxicity and foul ordour. One of methods of its removal is adsorption. Activated carbon is a widely used … …American Journal of Environmental Sciences, Vol. 10, Issue 4 · 17 Jun 2014 · 8,480 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 · 7,110 accessesView PDFCite
Research ArticleOpen accessIn the abstractWheat Production and EconomicsElgilany Ahmed, Jamalludin Sulaiman, Saidatulakmal MohdProblem statement: The crop in the irrigated scheme has faced by manifold problems contributed to low level of productivity and high cost of production of wheat. The crop is commonly produced under pump irrigation from the River Nile. In River Nile State (RNS), wheat is grown under the irrigated sector, the State is considered as a suitable environment for producing … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 3 · 4 Aug 2011 · 10,569 accessesView PDFCite
Research ArticleOpen accessIn the abstractCorn (Zea Mays L.) Plant Characteristics and Grain Yield Response to N Fertilization Programs in No-Tillage SystemKesi Liu, Pawel WiatrakProblem statement: Nitrogen application timing and Nitrogen (N) rate are two important factors to influence corn production in No-Tillage (NT) system, but N recommendations may need to be revised due to insufficient rainfall in dryland rain-fed environment. Approach: This study was to determine the effects of two N application timing (planting and split application at planting and V6 corn growth … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 1 · 25 Mar 2011 · 8,340 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Cooling and Supplemental Bovine Somatotropin on Milk Production relating to Body Glucose Metabolism and Utilization of Glucose by the Mammary Gland in Crossbred Holstein CattleSiravit Sitprija, Somchai Chanpongsang, Narongsak ChaiyabutrProblem statement: The low milk yield and shorter persistency of lactation of dairy cattle is the major problem for the dairy practices in the tropics. High environmental temperatures and rapid decline of plasma growth hormone level can influence milk production. Regulation of the milk yield of animals is mainly based on the mechanisms governing the quantity of glucose extracted by … …American Journal of Biochemistry and Biotechnology, Vol. 6, Issue 3 · 30 Sep 2010 · 7,341 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Municipal Solid Waste Compost on the Growth and Production of Vegetable CropsA.E. Ghaly, F.N. AlkoaikProblem statement: MSW has traditionally been dealt with thorough the practice of land filling and incineration. However, deleterious environmental impacts have promoted municipalities in Canada to recycle non-putrescible wastes and compost the putrescible ones. This study aimed at evaluating the effect of MSW compost on the growth and production of three vegetable crops (potatoes, corn and squash). Approach: Each crop … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 3 · 30 Sep 2010 · 8,798 accessesView PDFCite
Research ArticleOpen accessIn the abstractSupercritical Ethanol Liquefaction of Swine Manure for Bio-Oils ProductionShuangning Xiu, Abolghasem Shahbazi, Lijun Wang, Carlington W. WallaceProblem statement: Environmental problems associated with animal waste are the most critical challenges faced by the US intensive confinement livestock industries. There is an import and urgent need to develop an efficient way to reduce the pollution of animal waste while extracting valuable energy. Supercritical liquefaction processing of swine manure into a liquid fuel was considered as a cost-effective approach … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 8,245 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Dietary Protein and Lysine on Performance and Carcass Yield of TurkeysF. Peñaranda-Ali, R. Santos-Ricalde, L. Sarmiento-Franco et al.Problem statement: There is a concern related to loss of nitrogen to the environment from animal manure and the high cost of the protein supplement. Thus, the current study was undertaken to determine the effect of reduction of CP and increased of lysine on growth and carcass yield in turkeys. Approach: A factorial experiment was carried out with commercial turkeys … …American Journal of Animal and Veterinary Sciences, Vol. 5, Issue 1 · 31 Mar 2010 · 7,637 accessesView PDFCite
