Abstract

The local variety of corn in North Sumatra (Zea mays L.) exhibits production weaknesses, particularly in the Labuhanbatu area, where yields remain low. This study aims to evaluate the growth of local corn plants in North Sumatra after applying various doses of potassium chloride (KCl) fertilizer. The research was conducted in an experimental field located in Perbaungan Village, Bilah Hulu District, Labuhanbatu Regency, North Sumatra, from December 2024 to February 2025. The study employed a Non-Factorial Complete Random Design (RAL) consisting of five treatment levels, each replicated four times: Control, 2 grams of KCl per polybag, 4 grams of KCl per polybag, 6 grams of KCl per polybag, and 8 grams of KCl per polybag. The results indicated that the most effective treatment was the P4 treatment (8 grams per polybag). Corn plants that received KCl fertilizer demonstrated superior growth to those that did not or were in the control group.
