Comparative study of herbicides on yield and economics of wheat

A field experiment was conducted during the winter seasons of 2012–2013 in Chandra Sekhar Azad University of Agriculture and Technology, Kanpur (U.P.). Grain and straw yield varied significantly due to different herbicide and herbicidal combination. Twice hand weeding plot recorded significantlyhigher grain as well as straw yield. However, the sole application of herbicides, sulfosulfuron and carfentrazon-ethyl did not differed significantly from each other in respect of grain and straw yields but these obtained significantly higher grain and straw yield in sole application of metsulfuron-methyl and Clodinafop. The higher net income (Rs 57061/ha) and B: C ratio (2.25) were found with the application of sulfosulfuron (25g a.i./ha) + Carfentrazon (10g a.i./ha) followed by application of sulfosulfuron (25g a.i./ha) and carfentrazon-ethyl (15g ai/ha) net income (Rs 56519/ha) and B: C ratio (2.24).
