Komponen Keragaman Berbagai Karakter Populasi Tanaman Kacang Tanah (Arachis Hypogaea L.) Pada Berbagai Dosis Pupuk Fosfor

ABSTRACT
Peanut (Arachis hypogaea L.) is an essential commodity as a source of protein and vegetable oil; however, its productivity remains low. This study aimed to evaluate the phenotypic variation, heritability, and inter-character relationships of peanut genotypes under different phosphorus fertilizer doses. The research was conducted using a randomized block design with two factors. The first factor was six peanut varieties: Kancil, Katana 2, Garuda, Gajah, Tala 1, and Zebra. The second factor was three phosphorus fertilizer doses: 0 kg.ha-1, 45 kg.ha-1, and 63 kg.ha-1, with three replications. Data were analyzed using analysis of variance to calculate heritability and character correlations. The results showed significant genetic variation in flowering time, maturity time, plant height, pod weight, and seed weight. Phosphorus fertilizer doses influenced the number of pods, seed weight per plant, and seed weight per square meter. High heritability was observed in flowering time and seed weight per square meter. Phenotypic correlations revealed strong relationships between the number of pods and seed weight. Flowering time, plant height, number of pods, and seed weight were identified as effective selection criteria for yield improvement. The findings suggest that phosphorus fertilization and character selection can significantly enhance peanut productivity.
