Management of weeds in direct-seeded rice

A field experiment was conducted during the Kharif season of 2012 to 2014 for three years at Agricultural Research Station, Vadgaon Maval, Pune, Maharashtra to find out the efficacy of different chemical and mechanical weed control methods and its economics in direct-seeded rice. From the pooled data it was observed that the pre-emergence application of oxyfluorfen 0.150 kg/ha and post-emergence application metsulfuron-methyl + chlorimuron-ethyl 0.004 kg/ha as weed control measure in direct-seeded rice gave the highest net returns ( 57,063/ha) with higher B:C ratio (2.3) having lower weed index (2.96) and higher weed control efficiency (91.08%).
