Abstract

Aim: To ameliorate the inland saline water through biochar for enhancing the pond water productivity and utilize the vast resources of salt affteced land and ground saline water efficiently for aquaculture.

Methodology: A 50 days incubation study was conducted to understand the ameliorating effects of sugarcane bagasse biochar on the inland saline sediment and water. Biochar was applied at the rate of 100 g and 200 g in both sediment and water, respectively.

Results: Significant (P≤ 0.05) increase in pH, available-N, potassium, available-Pand decrease in total alkalinity was observed in all the treatments. The primary productivity significantly increased (P≤ 0.05) in all the treatments, and the maximum was observed in T4 treatment (0.173 mg m^-3).      

Interpretation: The sediment mixing and water application differ in their effect on the primary productivity and physico-chemical properties of inland saline pond water. The study will help in developing protocol for the application of agro-waste-derived biochar in the inland saline pond aquaculture system.
