Table 3 in Influence of Mycorrhizae and Irrigation on Growth and Mineral Uptake by Corn (Zea mays L.) Seedlings in a Calcareous Soil

Table 3. Analysis of variance for macronutrient (N, P, K, Mg and Ca) uptake by shoots of corn seedlings. Numbers are P values with F statistics in parentheses. Plants were grown in Guam cobbly clay soil, inoculated or not inoculated with Glomus aggregatum, and provided one of four levels of water.
