Aquaculture Effluent: Effect on Yield, Nutrient Content and Uptake in Salicornia bachiata Roxb

Abstract

The feasibility of aquaculture effluent as irrigation water for Salicornia brachiata Roxb. was determined to access the effect of effluent on fresh biomass, dry biomass, nutrient content and uptake. A field experiment was conducted using split plot design (SPD) with three factors (S- Sources of irrigation, M-Methods of sowing, F-Levels of fertilizer) at Central Soil Salinity Research Station, Dhanti-Umbharat, Navsari, India. The fresh and dry biomass yield of Salicornia was higher with the application of aquaculture effluent water to sea water irrigation. An application of 125:75:50 RDF of NPK conspicuously increased the fresh and dry biomass yield. The interaction study between the aquaculture effluent irrigation and 125:75:50 RDF of NPK on the fresh and dry biomass yield was significant. The individual effect of aquaculture effluent and 125:75:50 RDF of NPK were significant in the plant primary and secondary nutrient content and uptake. Concomitantly, the interaction of aquaculture effluent irrigation and 125:75:50 RDF of NPK was significant in plant primary and secondary nutrient uptake. In completion of the analysis, there was 40-50% nutrient saving with using aquaculture effluent.
