Abstract

WULAN F. A. DAMANIK. The Effect of Liquid Organic Fertilizer from Eggshells and Polyhalite Fertilizer on the Growth and Production of Sweet Corn (Zea mays saccharata Sturt) (Under the supervision of LISA MAWARNI as the Supervisory Committee). This study aims to evaluate the effect of liquid organic fertilizer (LOF) from eggshells and polyhalite fertilizer on the growth and production of sweet corn (Zea mays saccharata Sturt) of the Panglima variety. The study was conducted on Jl. Mahoni Perumnas Bagelen, Padang Hilir District, Tebing Tinggi City from March to August 2025. The study used a Factorial Randomized Block Design (RBD) with two factors: LOF dosage (0 and 180 ml/L) and polyhalite dosage (0; 86,07; 172,14; 258,14 kg/ha). The results showed that there was no significant effect of LOF, polyhalite, or their interaction on the parameters of plant height, stem diameter, leaf area, fresh root weight, fresh canopy weight, cob length, cob diameter, number of rows of kernels per cob, cob weight per plant, and cob weight per plot.
