EFFECT OF SHRIMP POND SLUDGE ON SEEDLING GROWTH OF MAHOGANY (Swietenia macrophylla)

Shrimp farming is economically admired and environmentally accused in Bangladesh. Environmental impacts of shrimp farm are related among others to management waste water pond sludge. Pond sludge has the potential be recycled also can used as organic manure considering presence high level nutrients matter. The performance was studied on Mahogany seedlings, which grown incremental (10%, 20%, 30% --------- 90%) mixture with soil compared other mixtures (soil chemical fertilizer; cow dung both fertilizer mixture) nursery. height, diameter, biomass (leaf, root shoot) nutrient concentrations (N, P K) leaf seedlings were measured after 4 month germination. It observed that height diameter growth, nitrogen phosphorus similar 90% mixture. production higher than
