Abstract:

A field experiment was conducted at Punjab Agricultural University, Krishi Vigyan Kendra, Pathankot, Punjab, India during Kharif 2016 and 2017 to identify the best herbicides-based weed management practices in maize (Zea mays L.). The treatments consisted of pre-emergence (PE) application of atrazine 1000 g/ha, pendimethalin 750 g/ha, pendimethalin 750 g/ha + atrazine 750 g/ha and post-emergence (PoE) application of tembotrione 110.2 g/ha, tembotrione 110.2 g/ha + atrazine 625 g/ha and 2,4-D amine salt 580 g/ha, hand weeding twice at 15 and 30 days after sowing (DAS) and weedy check. A randomized complete block design with three replications was used. The tembotrione 110.2 g/ha + atrazine 625 g/ha (tank mix) PoE at 25 DAS recorded the highest weed control efficiency (94.2%), maize grain yield (4.43 t/ha), net monetary returns ( 28047.3) and B:C (1.77).
