Weed control in puddled seeded rice (Oryza sativa) with herbicides

A field experiment was conducted during 1993 and 1994 to study weed control in puddled seeded rice (Oryza sativa L.). Post-emergence application of 2, 4-0 EE @ 0.4 kg/ha was found promising in reducing the weed dry weight/unit area and in enhancing the yield-attributing characters, viz. number of pan icles m(2), length of panicle, filled grains/panicle, grain weight/panicle, grain weight/panicle and grain yield of puddled broadcast 'Saket 4' rice a nd was found most economical too. Unchecked weed growth reduced the crop yi eld by 39% when compared with 2,4-0 EE.
