Research ArticleOpen accessEvery word in the titleDynamics 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. This study assessed the availability of mobile forms of phosphorus and potassium, alongside key physicochemical properties, including soil pH and cation exchange … …OnLine Journal of Biological Sciences, Vol. 26, Issue 1 · 14 Apr 2026 · 1,594 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffects of Crassocephalum bauchiense Ethanolic Extract on Reproductive Parameters in Rabbit Does Exposed to Potassium DichromateChongsi Margaret Mary Momo, Manfo Tsague Faustin Pascal, Nyambi Pasima et al.The present study was undertaken to evaluate the effects of Hutch leaves Ethanolic Extract (EE) on reproductive parameters, toxicity biochemical markers and oxidative stress indicators in does exposed to Potassium Dichromate (PD). Thirty-six nulliparous sexually mature does of eight months; weighing 2.80-3.00 kg were divided into six groups of six animals, comparable in terms of Body Weight (BW). After mating, … …American Journal of Animal and Veterinary Sciences, Vol. 16, Issue 2 · 19 May 2021 · 6,819 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffects of Potassium Fulvic Acid and DA-6 on the Growth and Yield of Tomato Cultivated with Rock WoolXiao Huaijuan, Zhou Yan, Mao Ke et al.Potassium fulvic acid and diethyl aminoethyl hexanoate (DA-6) are two kinds of growth regulators with yield increasing and quality improving. There are few reports on the effects of adding potassium fulvic acid and DA-6 in nutrient solution on the growth of soilless culture of vegetables. In this study, tomato was used as the test material to add different concentrations of … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 2 · 7 Apr 2020 · 8,285 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleRemoval of Coliform Content in Sewage Treatment Plant Using a Sand Filtration System with Potassium Permanganate PowderSona Pazdar, Saeid Eslamian, Seyedeh Zahra Hosseini-Teshnizi et al.Reuse of refined sewage with two goals of providing more water and protecting the environment from pollution is one of the solutions to water supply problems and one of the potential sources for irrigation in agriculture. The aim of this study is to evaluate the possibility of effluent disinfection using a sand filtration system to reduce microbial contamination with potassium … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 2 · 27 Jun 2019 · 7,583 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleHigh Level of Nicotianamine Synthase (NAS3) and Natural Resistance Associated Macrophage Protein (NRAMP4) Gene Transcription Induced by Potassium Nitrate in Trembling Aspen (Populus tremuloides)Karolina M. Czajka, Kabwe NkongoloChanges in gene transcription in response to excess metal concentrations have been reported in many organisms, including yeast, microorganisms and plants. Most investigations on the effects of nickel toxicity in plants use commercial salts whose effects have not been analyzed in detail. The main objective of the present study was to determine the effects of different doses of nickel nitrate … …American Journal of Biochemistry and Biotechnology, Vol. 14, Issue 3 · 15 Jul 2018 · 10,884 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Influence of Partial Substitution of Potassium by Sodium on the Growth Effect of SugarcaneChao Zheng, Yong-Xiang Huang, Jin Li et al.The effects of different potassium and sodium levels on the growth of Taisugar No. 22 (ROC22) were studied by potted nutrient solution-sand culture experiment in this paper. The results showed that under low potassium stress (0 mmol/L) supply, the proper application of sodium could significantly promote photosynthesis of sugarcane and dry matter accumulation, reduce root shoot ratio and promote shoot … …American Journal of Biochemistry and Biotechnology, Vol. 14, Issue 2 · 12 Jun 2018 · 11,314 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffects of Enriching Nitrogen and Phosphorus on the Growth of Sargassum Podacanthum Cultured in Potassium-Fortified Inland Saline WaterHa Thi Thu Bui, Trong Quoc Luu, Ravi FotedarPotassium-fortified inland saline water (K+ISW) has shown potential for growing marine species, including seaweed species. The response of a brown seaweed species, Sargassum podacanthum, to nitrogen and phosphorus enrichments were evaluated by culturing the species for 84 days in K+ISW and comparing it with Ocean Water (OW). The culture media were enriched weekly with ammonium chloride and sodium dihydrogen phosphate, … …American Journal of Applied Sciences, Vol. 15, Issue 3 · 6 Apr 2018 · 7,747 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Potassium Levels on Antioxidant Enzymes and Malondialdehyde Content under Drought Stress in Sunflower (Helianthus annuus L.)H. Soleimanzadeh, D. Habibi, M.R. Ardakani et al.Problem Statement: Drought stress as a major adverse factor can lower leaf water potential, leading to reduced turgor and some other responses and ultimately lower crop productivity in arid and semi arid zones. Sunflower is one of the main oil seed crops in Iran, where drought stress is the most limiting factor. Drought stress tolerance requires the activation of complex … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 1 · 31 Mar 2010 · 10,779 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFoliar and Soil Application of Potassium Nitrate Affects the Tolerance of Salinity and Canopy Growth of Perennial Ryegrass (Lolium perenne var Boulevard)S.J. Tabatabaei, F. FakhrzadTwo experiments were conducted to determine the effect of KNO3 application on perennial ryegrass salinity tolerance. Two NaCl levels (0 and 60 mM) factorially combined with four KNO3 (KN) levels (0, 5, 10 and 15 mM) as the treatments. The KN was applied either to the soil or foliarly sprayed. The results showed that in both experiments the increased salinity … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 3 · 30 Sep 2008 · 8,052 accessesView PDFCite
