Approach: After combining slope, aspect and hypsometric maps, the number of land … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 6,925 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Quick Method for Metarhizium anisopliae Isolation from Cultural SoilsM. A. Tajick Ghanbary, A. Asgharzadeh, A. R. Hadizadeh, M. Mohammadi SharifProblem statement: Fungi are one of the most active members in biological community of cultural soils. Many saprophyte and facultative parasitic fungi live in soil. Metarhizium anisopliae, one of the most famous soil inhabitant entomopathogens has a virulence potential on plant and animal pests. Approach: Introducing a new method for its isolation from soil was an applied method to find … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 2 · 30 Jun 2009 · 9,326 accessesView PDF Cite

Research ArticleOpen accessIn the abstractChemical and Physical Characteristics of Cocopeat-Based Media Mixtures and Their Effects on the Growth and Development of Celosia cristataYahya Awang, Anieza Shazmi Shaharom, Rosli B. Mohamad, Ahmad SelamatProblem statement: Cocopeat is considered as a good growing media component with acceptable pH, electrical conductivity and other chemical attributes but it has been recognized to have high water holding capacity which causes poor air-water relationship, leading to low aeration within the medium, thus affecting the oxygen diffusion to the roots. Incorporation of coarser materials into cocopeat could improve the … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 1 · 31 Mar 2009 · 19,015 accessesView PDF Cite

Research ArticleOpen accessIn the abstractHigh Quality Komatsuna (Brassica rapa L. nothovar) Production by Using Silicate Minerals Treated Nutrient SolutionSheheli Islam, Kumagai Kazunori, Noriko Takeda, Katsumi IshikawaProblem statement: Good water quality not only produces good crop yield, but also maintains environmental quality and so with plant, animal and human health. Therefore, protecting the quality of water by using non chemical materials is an emerging issue to be solved. Bakuhan seki having additional negative charge were found to have the capacity of improving condition of water while … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 1 · 31 Mar 2009 · 8,640 accessesView PDF Cite

Research ArticleOpen accessIn the abstractBiological Control of Rice Blast (Magnaporthe oryzae) by use of Streptomyces sindeneusis isolate 263 in GreenhouseM. Ebrahimi Zarandi, G.H. Shahidi Bonjar, F. Padasht Dehkaei et al.Soil Actinomycetes particularly Streptomyces spp. have antagonistic activity against wide range of plant pathogens. In the recent decades they have attracted high interests as biocontrol agents. In search for finding such principles, in vitro suppression of Magnaporthe oryzae the causal agent of rice blast disease was studied by use of Streptomyces sindeneusis isolate 263 in greenhouse.

Research ArticleOpen accessIn the abstractBioconversion of Carotenoids in Five Fruits and Vegetables to Vitamin A Measured by Retinol Accumulation in Rat LiversArmando Carrillo-Lopez, Elhadi M. Yahia, Gabriela K. Ramirez-PadillaProblem statement: Vitamin A deficiency is one of the most prevalent and major nutritional problems in developing countries, especially in young children. In many countries, a substantial proportion of dietary vitamin A is commonly derived from pro-vitamin A carotenoids obtained from colored fruits and orange or green vegetables. However, the bioavailability of retinol derived from carotenoids from these plant sources … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 2 · 30 Jun 2010 · 8,928 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordAn Edge Efficient and Lightweight Hybrid CNN Vision Transformer Network With CBAM for IoT Based Plant Disease DetectionNyabeye Pangop Doris-Khöler, Kengni Ngangmo OlgaDetecting crop disease early enough to act on it remains a bottleneck for smallholder and precision farming alike, particularly when diagnosis depends on manual inspection or lab analysis that cannot keep pace with an outbreak. We present AgriViTNet, a compact CNN-Vision Transformer hybrid built for exactly this constraint: It extracts local texture cues through convolution, relates them across the whole … …Journal of Computer Science, Vol. 22, Issue 9 · 20 Sep 2026 · 586 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordLarvicidal Activity of Spondias purpurea (Sineguelas) Leaf and Hylocereus costaricensis (Dragon Fruit) Stem Extracts Against Aedes aegyptiAlfredo V. Corpuz, Nigell Mikhail A. Gallardo, Ace Danielle C. AveroThe study determined the larvicidal activity of the different concentrations of Spondias purpurea and Hylocereus costaricensis extracts by measuring percent mortality in Aedes aegypti larvae, a primary vector of dengue and other arboviral diseases. The hypothesis proposed that combining both extracts would yield greater larvicidal activity due to potential synergistic interactions. Ethanolic extraction was used to isolate a wide array … …OnLine Journal of Biological Sciences, Vol. 25, Issue 3 · 20 Nov 2025 · 2,427 accessesView PDF Cite
