Among the 3 agrochemicals gypsum showed better phosphorous reduction at the dose of 40 mg/L followed by dolomite had comparatively high phosphorous reduction than lime application. The water quality parameters indicates that application of these chemicals at the rate of 20 and 40 mg/L dose level did not produce any adverse condition on the pH, alkalinity and hardness values. Hence, application of gypsum at the rate of 40 mg/L is recommended for use in aquaculture ponds to reduce the phosphorous load in the waterNot Availabl
