Growth and N and P Absorption Capability of Pistia Stratiotes Cultured in the Inorganic Fertilizer Enriched Media

Abstract

Pistia stratiotes are able to grow rapidly in culture medium given inorganic compounds. P. stratiotes cultured in a culture medium that has been given nitrates, phosphates and potassium (NPK) fertilizer. P. stratiotes cultured in a culture medium that has been given NPK fertilizer. A CRD with 5 concentrations of inorganic fertilizers tested, i.e. 0 (Co); 15 (T1); 20 (T2); 35 (T3); and 50 g / 10 L (T4). Observation of growth and decrease of the inorganic compound in culture medium was done 5 times, every 3 days. The results show that the best growth was identified in plants grown in T4. At the end of the experiment, 18.8 g BW with a daily growth rate was 17.9% of the baseline value of BW. On the 7th day of the experiment, the decrease was 0.187 mg / L (N) and 0.237 mg / L (P). So P. stratiotes were able to absorb relatively high N and P from water and use it for its growth.
