| Popis: | This study examines the influence of different amounts of potassium chloride (KCl) fertilization on plant growth, nutrient accumulation and content, nutrient ratios, and root colonization by indigenous arbuscular mycorrhizal (AM) fungi in maize (Zea mays L.). KCl was applied at the rate of 0, 0.25, 0.50, 1.00, 1.50, and 1.75 mg/kg of soil. Effect of KCl on indigenous AM formation and function was evaluated in terms of the extent of root length colonization, plant growth, and nutrient uptake. Increasing concentration of KCl fertilization proportionately limited the total root length colonized by AM fungi as well as the root length with different AM fungal structures. Maize plants raised on soils amended with different concentrations of KCl were significantly taller than those raised on unamended soils. KCl application also significantly increased the total root length and root dry weight. Nevertheless, KCl fertilization did not significantly alter the root/shoot ratios. Higher concentrations of nit... |
