Research ArticleOpen accessIn the keywordsRole of Evaporation in Degrading the "Oil Lakes"Al Rashed Ahamad, Colin BarkerProblem statement: Oil Spills are degraded by aerobic bacteria, water washing, evaporation and oxidation. In the absence of water the first two of these processes cannot operate. This is the situation in the low rainfall environment of the Kuwaiti desert where oil lakes still persist 20 years after the initial spills. The oils contain longer chain n-alkanes but have lost … …American Journal of Environmental Sciences, Vol. 7, Issue 3 · 11 Jul 2011 · 6,747 accessesView PDFCite
Research ArticleOpen accessIn the abstractSuppression of Bipolaris Leaf Blotch and Improvement of Wheat Growth by Plant Growth Promoting Rhizobacteria BacilliFarzana Zerin Eivy, Md. Tanbir Rubayet, Umakanta Sarkar, Md. Motaher HossainBipolaris leaf blotch, induced by Bipolaris sorokiniana, poses a notable risk to wheat cultivation, resulting in considerable annual declines in yield. Plant Growth-Promoting Rhizobacteria (PGPR) are acknowledged for their colonization of the wheat rhizosphere and provision of various advantages to plants, including disease control and improved growth. This investigation seeks to explore the feasibility of utilizing PGPR strains as a … …OnLine Journal of Biological Sciences, Vol. 24, Issue 3 · 12 Mar 2024 · 6,637 accessesView PDFCite
Research ArticleOpen accessIn the abstractInfluence of Sowing Dates, Soil Fertility and Crop Rotation System on Increasing the Yield Level of Various Varieties of Spring Wheat (Triticum Aestivum L.)K. Kunanbayev, V. Scoblikov, O. Solovyov et al.One of the most important branches of agriculture is crop production, from which people receive most of their basic foodstuffs, animal feed, and raw materials for the main industries. The most important goal of crop production is to increase yields in every possible way and, as a result, increase the production of grain, feed, and other products. The study aimed … …OnLine Journal of Biological Sciences, Vol. 24, Issue 1 · 20 Oct 2023 · 5,221 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhysico-Сhemical Parameters of Humic Substances of Brown Coal and their Effect on the Growth of Phoenix dactyliferaDamilya Konysbaeva, Bolat Yermagambet, Zhanar Kassenova et al.The motivation for the study was the need to obtain data on the effect of humic acids isolated from brown coal on soil fertility and plant development. In our study, we conducted experiments with plants to isolate humic substances from brown coal and study its physicochemical properties and the effect of the resulting fraction on the growth of Phoenix dactylifera … …OnLine Journal of Biological Sciences, Vol. 23, Issue 4 · 21 Sep 2023 · 4,936 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffectiveness of the Use of Ash and Slag Fertilizer on Ordinary Chernozem for Linum usitatissimum CropsGulmira Kyzdarbekova, Abilzhan Khussainov, Baurzhan Yessenzholov et al.Degradation, reduction of soil fertility, and accumulation of industrial waste is both global and national environmental problem. The purpose of the study is to evaluate the effectiveness and environmental safety of the use of fertilizers made from ash and slag on ordinary chernozem for common flax (Linum usitatissimum) crops. The laboratory experiments were conducted in the environmental protection laboratory. The … …OnLine Journal of Biological Sciences, Vol. 23, Issue 3 · 11 May 2023 · 5,161 accessesView PDFCite
Research ArticleOpen accessIn the abstractParticipation of Dermacentor Reticulatus Imago in the Reservation of Bovine Leukemia VirusY. Glazunov, Ya. Kabitskaya, L. Glazunova et al.Strict implementation of measures for the prevention and elimination of bovine leukemia does not allow completely getting rid of this disease. In all likelihood, the leukemia virus has additional transmission routes that have not been taken into account until today. In the Tyumen region, blood-sucking insects and ticks are widespread and take part in the transmission of some infectious and … …OnLine Journal of Biological Sciences, Vol. 22, Issue 4 · 2 Nov 2022 · 5,074 accessesView PDFCite
