Research ArticleOpen accessIn the keywordsPhysics Models of Pronuclear Movements in EggsKang Cheng, Changhua ZouBased on published experimental data, Newton's laws, and Coulomb's law, we investigate natural and normal pronuclear movements in wild types of eggs and develop physics models to fit the experimental data quantitatively. The difference between our modeling calculated results and the experimental data is less than 20%. Our models explain why and how pronuclei move in even or in variant … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 1 · 31 Mar 2005 · 6,743 accessesView PDFCite

The proven complex of technologies for embryo transplantation on an industrial scale will provide a 3-5-fold acceleration of reproduction of highly productive cows. As a result of scientific research, biotechnological methods of accelerated reproduction of dairy cattle have been substantiated and introduced … …OnLine Journal of Biological Sciences, Vol. 24, Issue 4 · 14 Oct 2024 · 4,298 accessesView PDFCite
Case ReportOpen accessIn the keywordsEffects of Foliar Applications Mulberry Leaf Enzyme Solution Fertilizer on Growth and Quality of Hydroponic Chinese CabbageLi Yang, Fan Yuting, Du Qingjie et al.To investigate the effects of foliar applications mulberry leaf enzyme solution fertilizer on growth, nutritional quality, photosynthetic characteristics, mineral elements, and antioxidant enzyme system of hydroponic Chinese cabbage, Chinese cabbage Zheng bai'886'was used as experimental material. In this study, we mainly selected seven different fermentation periods (CK: Distilled water, T1-T6, the fermentation days were 20, 35, 50, 65, 80, and … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 4 · 7 Jan 2023 · 5,347 accessesView PDFCite
Research ArticleOpen accessIn the keywordsApplication and Prospect of CO2 Enrichment Technology in AgricultureBingbing Wang, Xiangjie Lu, Wanlin Gao et al.With the increasing consumption of fossil fuels for human activities, the emissions of greenhouse gases, such as CO2, have significantly increased, resulting in an intensified greenhouse effect. As an important element for plant photosynthesis, CO2 enrichment in an appropriate environment can promote photosynthetic rate, organic matter accumulation and the growth rate of plants. The CO2 enrichment technology should be widely … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 1 · 10 Feb 2022 · 6,454 accessesView PDFCite
Review ArticleOpen accessIn the keywordsExploring the Potential for Concentration of Nutrients from Urine Using Solar Evaporation and Carbon Dioxide Trapping of AmmoniaTesfamariam Y. Debessai, Ababu T. Tiruneh, Gabriel C. BwembyaNutrients derived from urine such as nitrogen, phosphorous and potassium constitute valuable sources of fertilizers needed for growing plants and as alternatives to commercial fertilizers. Concentration of nutrients available from urine provides advantages of reducing the volume of transportation, the health risk and making nutrient application to soil stable and suitable. An exploratory review of a possible technology for concentration … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 4 · 28 Oct 2019 · 7,167 accessesView PDFCite
Research ArticleOpen accessIn the keywordsResponses of Grain Yield and Nutrient Accumulation to Water and Foliar Fertilizer Management in Upland and Wetland Rice VarietiesNatdanai Juntakad, Sittichai Lordkaew, Sansanee Jamjod, Chanakan Prom-u-thaiThis study evaluated the effects of water and fertilizer managements on grain yield and nutrient accumulation in upland and wetland rice varieties. The two rice varieties representing upland (KH CMU) and wetland (CNT1) ecotypes were grown in different water conditions and fertilizer managements. The interaction between variety and water condition had significantly affected on grain yield and straw dry weight. … …OnLine Journal of Biological Sciences, Vol. 18, Issue 3 · 28 May 2018 · 8,356 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDisposal of Agro-Industrials Wastes as Soil AmendmentsAli Mekki, Fatma Arous, Fathi Aloui, Sami SayadiWe investigated the fertilizing potential of three agro-industrial wastes (Compost (C), Dehydrated Manures (DM) and Digestate (D)) on soil properties, on seeds germination and the plants growth. Results showed that the addition of wastes modified several soil properties as pH, Electrical Conductivity (EC), Water Retention Capacity (WRC) and Soil Organic Matter (SOM). Hence, SOM increase from 1.5% in unamended soil … …American Journal of Environmental Sciences, Vol. 9, Issue 6 · 11 Jan 2014 · 7,014 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 abstractCombination of Organic, Chemical and Biological Fertilizers to Accelerate Mangrove Growth on the East Coast of Sumatra, IndonesiaBudi Utomo, Yuda Ilham Ramadhan, Yunasfi et al.Efforts to rehabilitate mangroves often do not yield satisfactory planting results. Low maintenance measures due to the tidal situation of the area make it difficult for rehabilitation actors to carry out fertilization and insertion. This study aims to increase the growth of Rhizophora mucronata with fertilization treatment during planting with various biological fertilizers. The study was designed using a completely … …OnLine Journal of Biological Sciences, Vol. 25, Issue 3 · 24 Oct 2025 · 2,498 accessesView PDFCite
Research ArticleOpen accessIn the abstractDynamics of Mobile Phosphorus and Potassium in the Soils of Agricultural Lands of Kostanay RegionAlmabek Nugmanov, Aliya Yskak, Tatiana Paramonova et al.Soil phosphorus deficiency is a growing constraint on crop productivity in the agricultural lands of the Kostanay Region, Republic of Kazakhstan, yet systematic data on the spatial dynamics of mobile phosphorus and potassium across soil types remain limited.
