摘要：
An experiment was conducted during the winter of 1994-95 and 1995-96 at Banswara, to find out effective and economical weed-control measure under various N application conditions in winter maize (Zea mays L.). Maximum weed-control efficiency (69.5%) was achieved with atrazine 1.0 kg/ha 30-35 days after sowing, being on a par with its pre-emergence application (60.4%). Benefit:cost ratio also followed similar trend.
