YIELD OF FLUE-CURED TOBACCO AFFECTED BY MYCORRHIZAL AND SOIL pH
Abstract
The inoculation with vesicular mycorrhizal fungi (VMF) increase of the quality seedling and yield crops. The objective this study were to evaluate the influence of VMF and soil pH in the seedling formation and leaf yield production of flue-cured tobacco. The seedling formation in soil with three levels of pH (4.7, 5.0, and 5.4) and with and without VMF. Eight seedling was conducted by treatment. In four seedling, root morphology, mycorrhizal infection and dry matter was evaluated. The other four was transplanted to pot contend 7 kg of soil with three levels of pH (4.7, 5.0, and 5.4). The planta was cultivated until leaf maturation. In the nursery, the raise of soil pH improved quality of tobacco seedling production. The inoculation of mycorrhizal increase the root length, root surface area, and dry matter of the seedling in lower soil pH, and leaf dry matter when transplanted by lower soil pH. Seedling growing in sói' without exchangeable Al produced highest leaf dry matter, independent of mycorrhizal or field soil pH. Seeding inoculated with VMF in high soil pH, decreasing leaf dry matter when transplant to lower field soil pH.
