Abstract


Sodium has the potential to replace the function of potassium in plant metabolic processes. Several studies have shown a role for sodium in stimulating plant growth. The purpose of this study was to obtain the proportion of sodium in replacing potassium in the growth of corn plants. This research was conducted in April - July 2019 at the Greenhouse and Plant Laboratory of the Politeknik Lamandau. This research was arranged using a completely randomized design with a fertilization treatment consisting of 100 kg. ha-1 KCl (K100), 75 kg. ha-1 KCl + 25 kg. ha-1 NaCl (K75 + Na25), and 50 kg. ha-1 KCl + 50 kg. ha-1 NaCl (K50 + Na50) with six replications. The results showed that sodium was able to partially replace the role of potassium in the growth of maize plants. Fertilization of Potassium 50% + 50% sodium was able to show the same growth with K100% fertilizer in forming canopy and root dry weight in the vegetative period of maize.
