ABSTRACT: This study was conducted in a greenhouse to evaluate the influence of Phosphorus homeopathy dinamizations and levels of mound nets of termites material on components of growth and absorption of P in sorghum plants. The experimental design was completely randomized in a factorial 4 x 5, with four replications, whose factors were four levels of mound nets of termites material (0, 25, 50 and 75 g dm-3) and five levels of dynamizations of homeopathy Phosphorus (0, 6, 12, 18 and 30CH). The doses of nets material were homogenized with subsamples of 3.5 dm-3 of soil, put in plastic pots, which were grown, after thinning, nine plants of sorghum (Sorghum bicolor (L.) Moench) during 60 days after the sowing. Volumes of 1 mL of each homeopathy Phosphorus were solubilized in 1000 mL of water and this solution were applied weekly 250 mL per pot until the next harvest. After harvest, it was evaluated the shoots and roots dried materials. The homeopathy Phosphorus influenced significantly (p <0.01) shoots and roots, whereas the nets material only influenced (p <0.05) the production of shoot dry matter. From the regression equations adjusted were estimated increases in the traits of values studied in relation to the control, with emphasis on the shoot dry matter production (76.2%) with the Phosphorus 30CH and (7.9%) with the nets material, applied at a dose of 75 g dm-3. The homeopathy Phosphorus in view of the results presented, stimulates further studies to better evaluate its performance under different conditions of crop production.
