INDIGENOUS VESICULAR MYCORRHIZAL FUNGI EFFECT ON MAIZE UNDER DIFFERENT TEXTURES
Journal Title: Earth Sciences Pakistan - Year 2018, Vol 2, Issue 2
Abstract
Plant health and biomass relies on nutrient availability and the efficiency with which nutrients are taking in by plants. Vesicular Arbuscular Mycorrhiza (VAM) is a symbiotic association between plant roots and fungus. VAM improve plant growth by modifying its rhizosphere soil and helps in nutrient uptake by plants. Our aim was to evaluate the growth of maize (Zea mays) and quantify mycorrhizae under different textures and in phosphorous deficient soils. Treatments include different types of soil texture (pure soil, pure sand and 1:1 soil+sand) along with recommended rate of nitrogen and potassium fertilizer while no phosphorous fertilizer was used. Root colonization, growth rate of plant, biomass of plant root and shoot and effect of VAM and roots on rhizosphere soil pH were observed. Results showed that shoot biomass was significantly improved in plain soil treatment as compared to sandy texture soils. Root:shoot ratio was significantly decreased in plain soil as compared to plants in sand. pH was reduced in all treatments significantly. Root colonization ranges from 40-49% and colonization rates higher in sandy soils than others. Results suggested that VAM infection show well growth in its natural environment and improve plant growth and yield.
