Sowing is prime operation in cultivation practice of any crop which directly affects production. Therefore, timely sowing is necessary with available sources of power. Intercropping being one of the traditional practices of crop production and there are no seed drills to both main crop and inter-crop in a single pass. To overcome this problem, the present seed cum fertilizer has to be modified to suit the requirement of the intercropping practice. The seed drill was modified by partitioning into 3 compartments in the seed hopper to suit the 2:1 and 8:1 intercropping ratio using two MS plates which are movable within the hopper for a predetermined distance with the help of a screw a handle mechanism. The modified seed drill was calibrated in the laboratory to check the seed rate of Redgram and soyabean. The seed rate of the both type of seed were within the recommended rates. The variation of seed flow in different furrow openers were less than 10 % as recommended by the BIS. The modified seed drill was evaluated in the field condition to check its performance. The average field capacity was found to be 0.25 ha/h at a forward speed of 2.8 kmph. The average field efficiency was found to be 70 %.
