Study of Oxalate Content in Green Amaranth (Amaranthus tricolor L.) Cultivated under Hydroponic and Non-Hydroponic Systems

Abstrak

Green amaranth (Amaranthus tricolor L.) is commonly cultivated by the community using both hydroponic and non-hydroponic systems. This plant contains antinutritional compounds, notably oxalates. The present study aimed to determine the oxalate content in green amaranth cultivated under hydroponic and non-hydroponic conditions. This study was using a single-factor experimental design with two treatment levels: P1 = hydroponic cultivation and P2 = non-hydroponic cultivation of green amaranth. Parameters observed included light intensity, temperature, air humidity, pH, leaf thickness, nitrogen uptake, phosphorus uptake, and oxalate concentration. The results indicated that light intensity, temperature, and air humidity did not differ significantly between the two cultivation systems. However, pH values showed notable differences, while leaf thickness and phosphorus uptake remained consistent across treatments. Nitrogen uptake varied between systems. Furthermore, leaf thickness, nitrogen uptake, and phosphorus uptake exhibited no significant correlation with oxalate levels. Overall, oxalate content in green amaranth was statistically similar between hydroponic and non-hydroponic cultivation methods.
