Research ArticleOpen accessPhrase in the titleTHE IMPACT OF THE POLYMER COATING NUTRISPHERE™ IN INCREASING NITROGEN USE EFFICIENCY AND CORN YIELDTimothy A. Smith, Ronnie W. Heiniger, Pawel WiatrakCurrently, it is estimated that 50 to 60% of the N applied fertilizer is actually utilized by the crop with the remaining N lost through leaching or denitrification. A three year study was conducted at eight locations in North Carolina to examine the impact of Nutrisphere™ on corn yield, optimum N rate, maximum yield, tissue N concentration, plant biomass and … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 1 · 21 Dec 2013 · 8,037 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Maize Potato Intercropping and Different Fertilization Methods on Rhizosphere Soil Microorganisms and Yield of PotatoHuanjin Ma, Shengguang Xu et al.A field experiment with three replicates was conducted to explore the effects of maize-potato intercropping and different nitrogen application strategies on rhizosphere soil microorganisms and potato yield. Microbial community analysis was based on relative abundance. Maize-potato intercropping improves land use efficiency, yet how differentiated nitrogen management regulates rhizosphere microecology and potato productivity in this system remains unclear. Clarifying nitrogen-mediated shifts … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 3 · 14 Sep 2026 · 790 accessesView PDFCite
Research ArticleOpen accessIn the abstractGrowth Performance Serum Biochemical and Hematological Parameters of Lambs Fed with Ration Containing Nigella Sativa Meal in Different Feed FormsNisa Nurmilati Barkah, Yuli Retnani, Komang Gede Wiryawan, Annisa RosmaliaNigella Sativa Meal (NSM) as a byproduct from Nigella sativa oil production contains high crude protein, but it is easily converts into ammonia (NH3-N) in the rumen. The processing of feed containing NSM into mash, pellet and wafer forms is expected to optimize the use of NSM as a protein source in feed. The objective of this study was to … …American Journal of Animal and Veterinary Sciences, Vol. 16, Issue 4 · 25 Nov 2021 · 6,451 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigation of the Photoheterotrophic Hydrogen Production of Rhodobacter sphaeroides KCTC 1434 using Volatile Fatty Acids under Argon and Nitrogen HeadspaceRuby Lynn G. Ventura, Jey-R S. Ventura, Young-Sook OhIn this study, the photo fermentative H2 production of Rhodobacter sphaeroides KCTC 1434 was investigated using acetate, propionate and butyrate under argon and nitrogen headspace gases. The highest H2 yield and Substrate Conversion Efficiency (SCE) were observed from butyrate (8.84 mol H2/mol butyrate consumed, 88.42% SCE) and propionate (6.10 mol H2/mol propionate consumed, 87.16% SCE) under Ar headspace. Utilization of … …American Journal of Environmental Sciences, Vol. 12, Issue 6 · 30 Nov 2016 · 9,058 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of Wheat-Chickpea Intercrops as Influenced by Nitrogen and Weed ManagementA. Abdulahi, A. Dabbagh Mohammadi Nassab, S. Nasrolahzadeh et al.Wheat and chickpea are most important crops in dryland farming areas of Iran. Weeds have major impact on chickpea grain yield. This experiment was carried out to increase land use efficiency and weed suppression through intercropping in dryland agricultural research station-Sararood, Kermanshah, Iran during 2008-10. The experimental design layout was factorial split plot based on randomized complete block design with … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 4 · 4 Dec 2012 · 8,681 accessesView PDFCite
Research ArticleOpen accessIn the abstractCorn Response to Nitrogen Timing and Rate under Strip Tillage and Low-Yield Environment in Southeastern Coastal PlainsPawel Wiatrak, Ahmad Khalilian, Guihua ChenProblem statement: Insufficient rainfall under low yield environment may affect nitrogen management, plant growth indices and grain yields of corn (Zea mays L.). Approach: The objective of this study was to determine the effects of two N application timings (all at planting and as split application with N applied at planting and V6 stage) and five N fertilizer rates (0, … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 1 · 10 Mar 2011 · 7,992 accessesView PDFCite
Research ArticleOpen accessIn the abstractPlants Responses to Nutrients Follow the Saturation Kinetic Typical of Enzyme Systems: Biological, Economical and Environmental ImplicationsR.P. LanaAgricultural efficiency has been associated with high plant productivity. However, it is dependent on fertilizers, which are nonrenewable resources. Crop production response to fertilizers is hyperbolic, following the Michaelis-Menten model and the law of diminishing return. Data of crop production (barley, bean, corn, cotton, soybean and wheat) as a function of nitrogen, phosphorus, and potassium fertilization were analyzed by Lineweaver-Burk … …OnLine Journal of Biological Sciences, Vol. 8, Issue 1 · 31 Mar 2008 · 6,895 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of Nitrogen and Potassium Uptake and Efficiency of Two Rice Varieties Cultivated on an Acid SoilShajarutulwardah Mohd Yusob, Osumanu Haruna Ahmed, Wan Asrina Wan Yahaya, Nik Muhamad Ab. MajidA pot study was carried with the following objectives: (i) To investigate N and K uptake of MR 220 and ARC 2 rice varieties grown on Bekenu series (Tipik Tualemkuts), and (ii) To investigate N and K use efficiency of MR 220 and ARC 2 grown on Bekenu series. Treatments evaluated were: (i) MR 220 and ARC 2 under fertilized … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 3 · 30 Sep 2007 · 7,846 accessesView PDFCite

Research ArticleOpen accessIn the abstractSugar Beet Performance Affected by Uniformity of N FertigationH. Nouri, M. S.M. Amin, S. J. Razavi et al.In common with the majority of crop species, in sugar beet nutrition nitrogen is an important element due to its role in sucrose utilization and plant growth. Application of precision agriculture, in order to apply the right amount of input at the right time in the right area, is appropriate to decrease chemical use and increase plant growth.
