      abstract = {The effects of two fertilizer combinations containing a  similar amount of nitrogen (N) and phosphorus (P) viz, cow  manure, urea and TSP @ 5000, 125 and 100 kg/ha,  respectively, (Treatment-1) and poultry-manure, urea and  TSP @ of 2000, 125 and 100 kg/ha, respectively,  (Treatment-2) on water and sediment quality parameters, and  biological production in six earthen ponds of 100 m2 each  for a period of eight weeks use studied. The values of N  nutrients (NH3-N, NO3-N, NO2-N) in water were significantly  lower but that of PO4-P were significantly higher in T-2.  Though not significant, total N and available P in the pond  sediment were lower in T-2. Four groups of phytoplankton  such as Bacillariophyceae, Chlorophycae, Cyanophyceae and  Euglenophyceae and two groups of zooplankton namely,  Crustacean and Rotifer were recorded from the experimental  ponds. The mean abundance of both phytoplankton (78.25 ±  6.33 x 104 cells/I) and zooplankton (57.63 ± 4.59 x104  cells/LI), were significantly higher (p<0.05) in ponds  treated with poultry manure (Treatment-2). The result of  the present study showed that despite iso-nutrients  content, poultry manure with urea and TSP is significantly  superior to cow manure with urea and TSP for maintaining  hydrological conditions and plankton production in earthen  ponds.},
