A study was carried out on development of bullock drawn dry paddy seed cum fertilizer drill for upland cultivation. Based on the physical characteristics of seed, development of dry paddy seed cum fertilizer drill was done. The seed and fertilizer box was made trapezoidal for free flow of seeds and fertilizer without bridging. The cup feed mechanism was selected for metering paddy seeds as there is no seed damage and hence does not affect germination. For fertilizer metering, an adjustable orifice type mechanism was provided. A clutch is provided for disengaging power to the metering mechanism during turning. For seed and fertilizer placement, shoe and shovel type of furrow openers were used. A provision was made to adjust the row to row spacing as per requirement. The average theoretical field capacity, effective field capacity and field efficiency was 0.151 ha·h-1, 0.11 ha·h-1 and 75.96% respectively.
