Research ArticleOpen accessIn the abstractConsistent and Proficient Algorithm for Data Gathering in Wireless Sensor NetworksP. Balamurugan, K. DuraiswamyProblem statement: A wireless sensor network is usually deployed in a harsh geographical area to gather data that can be delivered to the remotely located base station. Sensor nodes have irreplaceable energy source, limited computational capability and limited memory. It is a challenge to maximize the use of energy of these sensor nodes to extend the network lifetime. Approach: This … …Journal of Computer Science, Vol. 7, Issue 9 · 25 Jul 2011 · 6,732 accessesView PDF Cite

Research ArticleOpen accessIn the abstractBiocontrol of Soil Fungi in Tomato with Microencapsulates Containing Bacillus subtilisMarcela Hernàndez-Suàrez, Francisco Daniel Hernàndez-Castillo, Gabriel Gallegos-Morales et al.Problem Statement: An option to reduce pollution by synthetic agro-chemical in root plant disease management is the use of antagonist rhizobacteria belonging to Bacillus genus, because their inhibitory properties, stimulation of plant growth and crop yield increase. Approach: This study was carried out in order to evaluate if Bacillus subtilis strains could play an antagonists role of plant pathogens and … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 2 · 6 Jun 2011 · 8,925 accessesView PDF Cite

This study was conducted to investigate the risk factors for oral cancer among the subjects from the studied area. Approach: A case-control study of 350 … …American Journal of Pharmacology and Toxicology, Vol. 5, Issue 1 · 31 Mar 2010 · 10,080 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Study on Potentiality of Carbon Storage and CO2 Uptake in the Biomass and Soil of Coppice StandA. Khademi, S. Babaei, A. MatajiProblem statement: Enhancing carbon storage in terrestrial ecosystems, especially in the forests, is a key factor in maintaining the atmosphere's carbon balance. With regard to the importance of forest in carbon sequestration, this study attempted to investigate the carbon storage potential and CO2 uptake in oak coppice stand. Approach: After combining slope, aspect and hypsometric maps, the number of land … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 6,921 accessesView PDF Cite

Research ArticleOpen accessIn the abstractResidual Influence of Early Season Crop Fertilization and Cropping System on Growth and Yield of CassavaE. A. Makinde, O. T. AyoolaProblem Statement: In assessing fertilizer effects to sustain an intensive cropping system, the residual effects of fertilizer applied to preceding maize on the growth and yield of cassava and the effects of intercropping with soybean were studied in field experiments at Ibadan, Nigeria. Approach: Maize, established in April was fertilized using either organic manure or inorganic fertilizer or a mixture … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 4 · 31 Dec 2008 · 7,967 accessesView PDF Cite

Research ArticleOpen accessIn the abstractFoliar and Soil Application of Potassium Nitrate Affects the Tolerance of Salinity and Canopy Growth of Perennial Ryegrass (Lolium perenne var Boulevard)S.J. Tabatabaei, F. FakhrzadTwo experiments were conducted to determine the effect of KNO3 application on perennial ryegrass salinity tolerance. Two NaCl levels (0 and 60 mM) factorially combined with four KNO3 (KN) levels (0, 5, 10 and 15 mM) as the treatments. The KN was applied either to the soil or foliarly sprayed. The results showed that in both experiments the increased salinity … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 3 · 30 Sep 2008 · 8,052 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Effect of Adding Zeolite to Soils in Order to Improve the N-K Nutrition of Olive Trees. Preliminary ResultsR. Perez-Caballero, J. Gil, C. Benitez, J. L. GonzalezThis paper describes an experiment performed in order to study the possibility of using zeolite in organic olive groves. Soil and leaf analysis was performed and an increase in soil N levels was observed. Furthermore, higher levels of K in the soil and the trees point to the improved nutritional potential of these soils in terms of K, as a … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 1 · 31 Mar 2008 · 8,392 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEFFECT OF UREA WITH NUTRISPHERE-N POLYMER IN FALL AND SPRING NITROGEN APPLICATIONS FOR CORNPawel Wiatrak, Walter B. GordonPolymer coated urea may be a viable option to improve Nitrogen (N) uptake and corn (Zea mays L.) grain yields, especially in areas with relatively high soil N loss. The objective of this study was to evaluate the effect of two urea application timings (fall and spring) and three N rates (90, 180 and 270 kg N ha-1) with and … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 1 · 27 Dec 2013 · 8,150 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordTRANSPIRATION INFLUENCES CADMIUM UPTAKE BY BABY LEAF SPINACH (SPINACIA OLERACEA L.)Carlo Chehine, Paul Holford, Oula Ghannoum et al.Cadmium (Cd) is a toxic heavy metal whose concentration in soils is rising. This study investigated the effect of transpiration on Cd uptake by plants using soil conditions akin to those experienced by field crops. Two experiments were performed using baby leaf spinach (Spinacia oleracea L.) grown in soil containing Chloride (Cl) at a typical concentration of 70 mg kg-1. … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 4 · 23 Dec 2014 · 8,065 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordUsing Soil Plant Analysis Development Chlorophyll Meter for Two Growth Stages to Assess Grain Yield of Malaysian Rice (Oryza sativa)Asa Gholizadeh, Mohd Amin Mohd Soom, Anuar Abd. Rahim, Aimrun WayayokProblem Statement: Proper yield management in rice influences grain quality and quantity. Nitrogen site-specific management is also effective on final product of crops because excessive nitrogen application at any growth stage can reduce yield and increase disease incidence. In contrast, suboptimal nitrogen levels at discrete growth stages may substantially reduce plant productivity. The nitrogen status at specific growth stages may … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 2 · 6 Jun 2011 · 11,820 accessesView PDF Cite
