MARIUM TARIQ AND SHAHNAZ DAWAR
Abstract
After slight modification, pellets of Avicennia marina (Forsk.) Vierh plant parts viz., leaves, stem and pneumatophore were prepared from pyrophyllite at two different ratios 50:50 and 25:75 and incorporated in soil @ 3, 5, 7 and 10 pellets/pot. A pot experiment was designed to assess its effectiveness in promoting plant growth and suppression of root rot diseases. Observation showed that 5 leaves and stem powder pellets with 50:50 ratio gave significant results in increasing plant weight, height and controlling root rot diseases caused by pathogenic fungi viz., Rhizoctonia solani Kühn, Macrophomina phaseolina (Tassi) Goid and Fusarium oxysporum Schlecht on cowpea (Vigna unguiculata [L.] Walp) and brinjal (Solanum melongena L.) plants. Of the different dosages used, 5 pellets/pot were found to be best followed by 3 and 7 in controlling root rot diseases and promotion of growth parameters.
