Economic Threshold For Wild Radish (Raphanus Raphanistrum L.) Control In Wheat Fields, Özhan Boz
Economic Threshold For Wild Radish (Raphanus Raphanistrum L.) Control In Wheat Fields, Özhan Boz
Turkish Journal of Agriculture and Forestry
Field experiments were conducted in Aydın province in 1998 and 1999 to determine the economic threshold (ET) using florasulam + flumetsulam, 2,4-D amine, thifensulfuron methyl + tribenuron-methyl, and tribenuron-methyl for wild radish (Raphanus raphanistrum L.) in wheat. The effect of wild radish density (1, 2, 4, 8 and 16 plants m^{-2}) on wheat yield was investigated using an adjacent plot design with 4 fields. For each weed density, yield was compared with that in the adjacent weed-free control plot. The grain yield in wild radish-free wheat was 4079 kg ha^{-1} in 1998, 4369 kg ha^{-1} in 1999 and 4224 kg …
