Non-control of weeds will reduce wheat grain yield significantly (Sing et al., 2015). In Bangladesh, farmers use 2-6 tillage passes by 2-wheel tractor (2WT) to control pre-plant weeds and prepare the land to sow the seeds. Minimum soil disturbance is one of the key principles of conservation agriculture (CA). However, minimum soil disturbance planting systems could enhance weed infestation (Sing et al., 2015) if pre-plant weeds are not controlled properly. Although the use of herbicide is increasing quite rapidly in Bangladesh (Hossain, 2015), the use of non-selective herbicide (e.g., glyphosate) to control pre-plant weeds is limited due to higher price of glyphosate and non-availability at farmers' level. The Versatile Multi-crop Planter (VMP) (Haque et al., 2011) performs strip planting of various crop seeds and application of fertilizer in lines, and covering seeds simultaneously in a single pass operation. To manage pre-plant weeds in the field, the rotary shaft of VMP was redesigned with small blades attached between strips to cut the existing weeds while sowing seeds in the field. To evaluate the performance of the VMP for controlling pre-plant weeds in wheat crops, experiments were conducted at Rajbari, Rajshahi, and Thakurgaon districts of Bangladesh during 2015-16.
