PENGARUH APLIKASI HERBISIDA TUNGGAL DAN CAMPURAN TERHADAP PERTUMBUHAN DAN HASIL TANAMAN JAGUNG (Zea mays L.) DI LAHAN KERING

Abstract

This research aims to find out which herbicide application has the best effect on the growth and production of corn plants (Zea mays L.). This research used a non-factorial Randomized Block Design (RAK) consisting of one treatment factor with 8 treatment combinations and 3 replications, so there were 24 treatment combinations. Single and mixed herbicide treatments consisted of P₀ (no weed control), P₁ (mechanical control), P₂ (atrazine herbicide), P₃ (saflufenacil herbicide), P₄ (nicosulfuron herbicide), P₅ (atrazine + saflufenacil herbicide), P₆ (atrazine herbicide + nicosulfuron) and P₇ (herbicide atrazine + saflufenaci + nicosulfuron). The parameters observed in this study included the level of plant poisoning, flowering age (DAP), harvest age (DAT), cob weight per plot (kg), seed dry weight per plant (g). The research results showed that P5 treatment (herbicide atrazine + saflufenacil) could accelerate flowering time, harvest time, increase ear weight per plot and seed dry weight per plant, and the herbicide treatment did not result in poisoning of corn plants.
