Determination of the Best Integrated Weed Management System in Maize (Zea mays)

In order to determine the best integrated management system in maize field experiments were conducted at Tehran in Iran which revealed that maize grain yield in Double Row (DR) planting pattern was higher than in Single Row (SR) planting pattern in all plots (up to 1.0 t ha-1). Tank mixing atrazine with other preemergence herbicides significantly increased weed control at both planting patterns and the best was atrazine at dose of 1.0 kg ha-1 plus alachlor. Among Sulfonylurea herbicide, nicosulfuron gave the highest grain yield. The most efficient Foramsulfuron dosage was 37 g a.i. ha-1 which had highest grain yield. It was concluded that the best integrated management system in maize is integrating crop competitiveness with reduced herbicidal mixture and appropriate dosage.
