Aplikasi Gulma Siam pada Tanaman Jagung (Zea Mays L.) terhadap Pertumbuhan dan Serangan Hama Spodoptera frugiperda
Abstract
Maize (Zea mays L.) is a plant that is in great demand by Indonesian people, so farmers in indonesia plant many maize plants. This study aimed to determine the effect of the application of siam weed on the growth of maize and the attack intensity of Spodoptera frugiperda pest. This research was conducted in huluduwotamo village, Suwawa subdistrict, Bone Bolango Regency, from February to june 2021. This study employed a rendomized block design (RBD) consisting of four treatments : control (without siam weed), 10 tons/ha siam weed, 15 tons/ha siam weed, and 20 tons/ha siam weed. Furthermore, each treatment was replicated three times to obtain 12 experimental units. The data analysis method used analysis of variance with a least significant difference (LSD) test of 5%. The finding proved that the best siam weed treatment was at a dose of 20 tons/ha, which affected the growth of plant height, the number of leaves, and the number of fruits, but it was not optimal in suppressing the attack intensity of Spodoptera frugiperda pest.
