The effects of fallow and herbicide on wheat production at Canterbury


, : The effects of fallow and herbicide on wheat production at Canterbury. Proceedings of the forty second New Zealand weed and pest control conference: 213-216

Six experiments in 2 seasons at Ashburton (Winchmore), Templeton and Irwell/Lincoln investigated the effect of fallowing in combination with paraquat/diquat (at 0.6/0.1 kg/ha) applications, on the growth of spring wheat Oroua and Otane. A 6 week fallow increased leaf DW, LAI, total wt of straw and grain, spikelets/head and increased the yield of wheat by 20%. Herbicide, used instead of pre-plough cultivation, increased LAI, but this increase did not contribute to final wheat yield.
