Research ArticleOpen accessPhrase in the titleEvaluation 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 PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Nitrogen on Growth and Lipid Content of Chlorella pyrenoidosaSubhasha Nigam, Monika Prakash Rai, Rupali SharmaProblem Statement: In today’s scenario, microalgae are widely recognized as a promising source for biofuel production as a renewable source of energy. They are exceedingly rich in oil, which can be converted to biofuel. This paper deals with one of the method to enhance the lipid content in microalgae. Approach: Microalga, Chlorella pyrenoidosa, was grown autotrophically in batch culture and … …American Journal of Biochemistry and Biotechnology, Vol. 7, Issue 3 · 22 Sep 2011 · 12,285 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDetection of Soil Total Nitrogen, Phosphorus and Potassium Content Based on the Spectral Information of Citrus CanopyLin Yunshuo, Li Zhen, Lv Shilei et al.The content of total nitrogen, phosphorus and potassium in the soil is an important basis for calculating the best fertilization amount and realizing the reasonable fertilization of the orange planting soil in time and accurately. In this research, hyper-spectral technology is applied to detect the three soil nutrient elements in the cultivated soil of citrus trees. Four spectral bands with … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 2 · 17 Apr 2020 · 7,805 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffects of Nitrogen Fertilizer on Grain Yield and Fragrant Contents in two Thai Rice VarietiesAyut Kongpun, Chanakan Thebault Prom-u-ThaiNitrogen (N) is commonly applied in rice crop production for improving grain quality and productivity. This experiment aimed to evaluate how applying N fertilizer affects the concentration of 2-Acetyl-1-Pyrroline (2AP), the major fragrant compound in rice grains, between two selected rice varieties with high yield potential and fragrant scent, Pathum Thani 1 (PTT1) and RD22. Rice plants were grown in … …OnLine Journal of Biological Sciences, Vol. 21, Issue 3 · 18 Jul 2021 · 7,458 accessesView PDFCite
Research ArticleOpen accessIn the keywordsBiodegradation of Phenolic Compounds in Creosote Treated Wood Waste by a Composting Microbial Culture Augmented with the Fungus Thermoascus aurantiacusAbdel E. Ghaly, Bopeng Zhang, Deepika DaveProblem statement: Creosote is used as a wood preservative and water proof agent in railway sleepers, utility poles, buildings foundations and fences and garden furniture. It is a mixture of over 300 hydrocarbons which include 75% polycyclic aromatic hydrocarbons, 2-17% phenolic compounds and 10-18% heterocyclic organic compounds. Exposure to creosote may result in several health problems including damage to kidney, … …American Journal of Biochemistry and Biotechnology, Vol. 7, Issue 2 · 26 Aug 2011 · 9,446 accessesView PDFCite
Research ArticleOpen accessIn the abstractEfficiency of Nitrogen Fixation by Rhizobium Strains Associated With White Clover in the Ecuadorian Highlands Biological Nitrogen Fixation by White Clover in EcuadorDaniela Michell Chuquimarca Mamarandi, Venancio Saúl Arahana Bonilla, Paulina Andrea Cevallos Hidalgo et al.The objective of this research was to evaluate the nitrogen-fixing capacity of 30 strains of Rhizobium isolated from white clover nodules, collected in the provinces of Pichincha and Cotopaxi under greenhouse conditions. After isolation of the bacteria and authentication of the isolates, a greenhouse experiment was conducted, in a Completely Randomized Design (CRD), with three replications and two controls: with … …OnLine Journal of Biological Sciences, Vol. 26, Issue 4 · 4 Oct 2026 · 835 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Wheat Bran, EM Bacteria, Ammonium Nitrate and Fungal Additives on Fermentation and Forage Quality of Rice Straw SilageBin Yang, Jiahuan Liu, Dongmei Ma et al.The global ruminant industry is constrained by a persistent shortage of high-quality roughage, thus rendering the bioconversion of agricultural residues, such as rice straw, a critical priority. Nevertheless, the high lignification, silicification, and nitrogen deficiency of rice straw pose significant biological barriers to traditional ensiling. This study investigated the impact of various additives on rice straw silage quality. Six treatments … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 3 · 30 Sep 2026 · 642 accessesView PDFCite
Technical ReportOpen accessIn the abstractFish Pond Storage Preserves Chili Puree, but Nitrogen Flow-Through Fails: Unravelling the MechanismDaimon Syukri, Rina Yenrina, Rini et al.Perishable food preservation in rural and resource-limited settings remains a significant challenge, as conventional techniques frequently depend on synthetic additives or energy-intensive processes incompatible with green chemistry principles. This study evaluated fish pond immersion as a novel, low-cost preservation method for freshly ground chili purée, investigating its efficacy with and without continuous nitrogen gas flow. Chili purée samples were packaged … …OnLine Journal of Biological Sciences, Vol. 26, Issue 1 · 30 Mar 2026 · 1,344 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects Of Ultra-High Pressure and Thermal Treatment on Quality Characteristics of Prepared Mackerel Fish BallsBiaoshi Wang, Xiaojun Hu, Jingqiu Ma, Ying XuSafe and high-quality prepared foods are increasingly preferred by consumers.
