Abstract

Sweet corn is a high-value cereal crop whose productivity is often limited by weed infestation, especially under no-tillage (NT) systems. This study aimed to evaluate the effectiveness of Nicosulfuron as a follow-up herbicide after Paraquat application for weed control in sweet corn cultivation. The experiment was conducted at SPLPP Ciparay, Universitas Padjadjaran, from September to December 2021 using a factorial randomized block design with two factors and two replications. Paraquat was applied at doses of 0; 0.297; 0.594; and 0.891 kg ha⁻¹, followed by Nicosulfuron at 0; 0.080; 0.160; and 0.320 kg ha⁻¹. Observations included phytotoxicity, weed dry weight, crop growth, and yield. The results showed that Paraquat at 0.891 kg ha⁻¹ effectively suppressed total weed biomass, while Nicosulfuron at 0.160–0.320 kg ha⁻¹ controlled dominant weeds, particularly Paspalum conjugatum and Ageratum conyzoides. The combination of Paraquat 0.891 kg ha⁻¹ and Nicosulfuron 0.320 kg ha⁻¹ produced the lowest weed dry weight and highest sweet corn yield, indicating that sequential herbicide application is effective under NT systems.
