In coastal area interactions among air, water and soil take place. The nature of water and amplitude of the tidal regimes resulted in the poor understanding.The present study focused on a segment of the coastal zone of Bangladesh. Soils collected from the three islands were found to be rather similar as regard to chemical properties, although some variables differed significantly among the islands. No general pattern of significant variation was found location wise. Element concentrations of leaves of Sonneratia apetala showed significant variations among the islands. In most cases, location...

A field experiment was done at SAU Farm, in winter(10 Nov. 2004-07 Mar.2005)to investigate the effect of vermicompost and NPK (Nitorgen+Phosphorous+Potassium) on the growth, chemical composition and yield of wheat. The experimental soil was silty clay, pH 6.0. The treatments were 4 levels of vermicomposts viz. V0 (0 t ha-1), V1 (1 t ha-1), V2 (2 t ha-1), V3 (3 t ha-1), and 4 levels of fertilizers viz. F0 = (0-0-0 kg ha-1), F1 = low (40-30-20 kg ha-1), F2 = medium (80-60-40 kg ha-1), F3 = high (120-80-60 kg ha-1) of N-P2O5-K2O with 16 treatments combinations and 3 replications. The results...
