Author(s): Narendar Jannu, M Srinivasa Raju, KB Sunitha Devi, G Jaya Sree and A Srinivas
Abstract: A field experiment entitled “studies on economical weed control in direct seeded rice under rainfed condition” was conducted at agricultural college farm, Rajendranagar, Hyderabad, during kharif, 2010. The higher grain yield was obtained with T5– [Cyhalofop-butyl+ (Chlorimuron-ethyl+ Mestulfuron-methyl) @ 90+20 g ha-1] and it was found at par with T8–(Fenoxaprop-p-ethyl + Ethoxysulfuron @ 60+15 g ha-1), and also with farmers practice i.e. T10–(Two Hand weedings at 20 and 40 DAS). N, P and K uptake by grain at harvest was significantly more in T10–(Two Hand weedings at 20 and 40 DAS) followed by T5–[Cyhalofop-butyl+ (Chlorimuron-ethyl+ Metsulfuron-methyl) @ 90+20 g ha-1]. Both T10 and T5 were significantly superior to other weed control treatments. The highest gross (Rs.41256), net returns (Rs.24369) and BCR (2.44) were recorded by T5–[Cyhalofop-butyl+ (Chlorimuron-ethyl+Metsulfuron-methyl) @ 90+20 g ha-1].
