Manual weeding or herbicide application using manual operated tools/equipment are commonly used by farmers to manage weeds in Kharif season and they are laborious and time-consuming. During the rainy season, mechanical weed management is difficult in the early stages of crop growth due to prevailing environment. To address this issue, the ICAR-CIAE, Bhopal, conceived and developed a tractor-operated 6-row pre-emergence herbicide strip-application system used in conjunction with an inclined-plate planter to manage weeds in widely spaced crops. The developed pre-emergence herbicide applicator-cum-planter (PREHAP) was evaluated, during the Kharif  season, to compare its efficacy using different pre-emergence herbicides with hand weeding and inter cultivation between crop rows for weed management in soybean. The lowest weed density and weed infestation were observed with the broadcast application of pre-emergence herbicide with PREHAP followed by one hand weeding and resulted in highest soybean plant height, number of pods, seed yield, net economic return and B:C. The PREHAP that could spray herbicide in both band and wide area was found to be a good way to apply herbicide while sowing the crop .
