Yield and protein content of wheat varieties (Kalyansona and Ni-5642) as influenced by sublethal doses of herbicides

A field experiment on two wheat varieties namely NI-5642 and Kalyansona with foliar spray of three herbicides viz 2,4-D, atrataf and taphazine at three concentrations i.e. 250, 500 and 1000 ppm was conducted inrabi season of 1971. From the studies it was observed that all three herbicides at all the concentrations increased the protein content and the maximum increase was to the extent of 56.8 as percentage of control. Of the chemicals used 2,4-D at 500 ppm concentrations was effective in respect of protein content, yield and 1000 grain weight.
