EXPERIMENTAL EVALUATION OF TWO CHEMICAL FERTILIZERS IN RELATION TO WATER QUALITY AND PLANKTON PRODUCTIONV.P. Saini and M.L. Ojha*
Water quality and plankton production was studied in cement cisterns, treated with SSP (Single Super Phosphate) and urea. Two doses of each fertilizers, i.e. 12 and 25 mg/L SSP and 4 and 8 mg/L Urea were used. Weekly estimation of phyto and zooplankton population indicated highly significant effects of both the fertilizers as compared to control. The average population of zooplankton in low doses of SSP and urea were 1076 and 1089 Nos/L respectively. While in higher doses the respective population was 1198 and 1158 Nos./L in SSP and Urea. Whereas in control zooplankton population was only 679 Nos./L. Further, the higher average population of phytoplankton from SSP and Urea was 590 cell/mL (25 mg/L SSP) and 580 cell/mL (8 mg/L Urea) respectively. However, water quality parameters were not significantly affected by fertilization. Statistically analysis of phyto and zooplankton production showed the result as highly significant at 1% level of probability. Moreover, Duncans new multiple range test showed that all the treatments are significantly different from each other (P<0.05).
